Unable to Extract Numbers Using OCR Despite Performing Image Processing
I have images from a screen recording from which I am trying extract certain text and numbers.
I then crop the regions of interest (ROI) and proceed to resize the image from each ROI. Finally I apply various processing techniques such as filtering, adaptive histogram equalization, masking, binarization and morphological operations as shown below.
My code is shared as under
function [final_frame,point_cloud_block_values] = block_extractor_v10(img)

Facilitator Agent Brings AI-Powered Notetaking to Teams Chat
Facilitator Agent Extracts Value from Teams Chat
In an article last month, I discussed why Microsoft 365 Copilot works better for some people than it does for others. The article is based on a blog by Abram Jackson, a program manager working on Microsoft 365 Copilot, and one of the points he makes is that AI fails when it doesn’t have the right data to process. This is why Copilot is so good at summarizing a bounded set of data such as a Teams meeting transcript or email thread and less good at other tasks.
Which brings me to a new bounded AI use in the Teams Facilitator “collaborative communication” agent (see message center notification MC1017117, last updated 10 March 2025, Microsoft 365 roadmap item 476811). The agent has been available in targeted release and is heading for general availability in April 2025. Facilitator is available for meetings and chats, but here I focus on chats because this is an area where AI hasn’t ventured before. According to Microsoft, “the Facilitator creates and maintains an up-to-date summary of important information as the conversation happens, including key decisions, actions items, and open questions to resolve.”
The administrator documentation and user documentation and doesn’t need to be repeating here. Essentially, you’ll need a Microsoft 365 Copilot license to use Facilitator (otherwise known as AI Notes). Note generation is supported for English now with support for more languages in the pipeline.
Control over who can use Facilitator is exerted by allowing people access to the Facilitator app in the Teams admin center. Microsoft says that after general availability, the app is enabled by default and can be used in chats by enabling the AI Notes option (click the icon to the right of the Copilot icon). Let’s see what happens.
Using AI Notes in a Chat
When a chat starts, it’s an empty thread and there’s nothing for AI to process. In fact, AI cannot process information until it has sufficient data to understand what’s happening. This is what’s happening in Figure 1. Facilitator is enabled for the chat but only three messages are in the thread and that’s not enough.
This isn’t a problem because the intention behind Facilitator is that it will help chat participants understand what’s been discussed in a thread. It’s easy to understand the conversation after three messages. It’s much more difficult to do so after a hundred messages in a fast-moving debate. The same situation occurs for Microsoft 365 Copilot in a Teams meeting where a certain amount of data must accumulate in the meeting transcript before Copilot becomes active.
As the chat develops, Facilitator begins to generate notes (Figure 2) to capture the major points raised in the chat, any decisions made, and any questions that remain unanswered. Facilitator updates the notes displayed in the pane periodically and highlights new information that a chat participant hasn’t seen. Like other Copilot implementations, reference numbers allow users to access the source for a note.
At the end of the chat, any of the chat participants can ask Facilitator a question by using an @Faciliator mention and entering the question (Figure 3).
Alternatively, a participant with access to the AI Notes can copy the notes and paste them into the chat. This is a good way to share AI Notes with chat participants who don’t have a Microsoft 365 Copilot license as those people cannot enable and view AI Notes for the chat.
External Participants Turn Off Facilitator
The Facilitator agent can’t be used in chats that involve external participants (guest users or external federated chats). This is likely because no mechanism is available in a chat to allow people to grant consent for their messages to be processed by an agent. When people join a meeting, they have the chance to grant consent for transcription, and it’s the transcript that’s used by Microsoft 365 Copilot to summarize the meeting or answer questions about the proceedings.
Facilitator is a Nice Tool to Have
I like Facilitator very much. It’s an example of focused application of AI LLMs to reason over a bounded set of data to generate results that works well in practice. Facilitator is not enough to justify the full price of a Microsoft 365 Copilot license, but it is step in the right direction and is a sign that we’re moving away from what some call the “party tricks” of Copilot to the implementation of some really useful tools.
Insight like this doesn’t come easily. You’ve got to know the technology and understand how to look behind the scenes. Benefit from the knowledge and experience of the Office 365 for IT Pros team by subscribing to the best eBook covering Office 365 and the wider Microsoft 365 ecosystem.
Supply Chain Security Risk: GitHub Action tj-actions/changed-files Compromised
On March 14th, 2025, security researchers discovered a critical software supply chain vulnerability in the widely-used GitHub Action tj-actions/changed-files (CVE-2025-30066). This vulnerability allows remote attackers to expose CI/CD secrets via the action’s build logs. The issue affects users who rely on the tj-actions/changed-files action in GitHub workflows to track changed files within a pull request.
Due to the compromised action, sensitive CI/CD secrets are being inadvertently logged in the GitHub Actions build logs. If these logs are publicly accessible, such as in public repositories, unauthorized users could access and retrieve the clear text secrets. However, there is no evidence suggesting that the exposed secrets were transmitted to any external network.

Time to Remove the Old Report Message Add-Ins
Report Message and Report Phishing Deemed Unsafe by Microsoft
Message center notification MC1030003 (12 March 2025) brings news that the built-in Report button (Figure 1) is available for all Outlook clients (from these versions on). The older Report Message and Report Phishing add-ins are now in maintenance mode. Although they continue to work, Microsoft recommends that the add-ins should be removed before the time comes when Microsoft retires and finally removes the now-obsolete add-ins.
Microsoft cites many benefits for the new Report button, including support for reporting email delivered to shared mailboxes, better localization, and the ability to report messages from different places, like the preview window. My favorite is that users can’t report their own messages as junk because Outlook disables the Report button for messages sent by the mailbox owner. For now, this feature only seems to work in OWA and the new Outlook and sometimes it doesn’t work, but it’s certainly a good thing.
If users don’t see the Report button, it could be that the user reported settings in the Microsoft Defender portal need to be adjusted. These settings control whether users can submit messages suspected to be junk email or phishing attempts to Microsoft for analysis.
Some organizations don’t permit people to report email because they don’t want Microsoft personnel to be able to read the reported messages. That’s certainly a valid perspective, but phishing techniques evolve on an ongoing basis and a reported message could disclose a new technique that allows Exchange Online Protection to detect and block dangerous content. Overall, I think it’s best to allow users to report bad email.
Unsafe Add-ins
Rather alarmingly, the FAQ for the built-in Report button says that “there are security issues with the add-in which makes them unsafe for the organization” without saying or even hinting what those issues might be. The FAQ also says that the add-ins “can’t architecturally support functionality that customers keep asking for.” Again, no further information is given to back up the claim. It’s more likely that the problem is that these add-ins are COM-based. Microsoft is dumping this technology as it moves forward with the new Outlook for Windows.
Checking the Report Add-ins
Unless good reason exists not to use built-in client functionality, it’s best to use it rather than add-ins. Given the profusion of integrated apps that could appear in tenants due to Copilot agents, administrators are likely to be busy managing those apps. Getting rid of a few obsolete add-ins won’t ease the agent burden, but it’s step in the right direction.
Taking my own advice to heart, I checked in the Integrated apps section of the Microsoft 365 admin center to see if the Report Message and Report Phishing add-ins were still in use. As you can see from Figure 2, just one active user was detected.
The download option creates a CSV file that gives some details about the app and when it was used, but it doesn’t point to who is using the app. The app properties might be configured to allow access to the add-in to specific users or groups, and that could give a clue to who might be using it. But you’re out of luck if the app is configured for tenant-wide access.
Removing an Add-in
It’s always best to let users know that a change in coming. Microsoft says that people prefer the single Report button. In any case, changing from the add-in to the built-in report button shouldn’t prove too difficult for anyone, so I went ahead and removed the add-in from the set of Integrated apps (Figure 3).
It takes some time for a change like this to make its way to clients. Microsoft documentation says that it can take up to 24 hours before a newly deployed app appears in a client. The same applies to app deletions. My experience is that it can take longer before all clients receive updates. However, removed add-ins should disappear in a couple of days.
I’m glad to report that the removal of the old Report Phishing add-in from my tenant went according to plan. No squawking from annoyed users has happened so far. Maybe they haven’t noticed the change yet.

To pass a variable outside a parfor loop

How can I control a revolute joint with a stepper motor ?
Hello, I want to control a stage which is actuated by a lead screw and stepper motor. Ideally, I need to specify the velocity of the stage or angular velocity of the rotational joint 1 so that it rotates the screw. I used simscape to generate the block diagram from my CAD model from onshape (link below). Is there any way of doing this ? I have tried using the stepper motor model from the simelectronics library but had trouble connecting it to the joint.

Issue with serial communication blocks from support package for arduino nano(CH340 clone)
I’m using arduino nano(ch340) and implementing serial communication with the Raspberry Pi 4B. I’m using USB cable rather than onboard uart pins. I’ve been trying to send data through serial transmit block (from nano) but no results at all. You cannot use ‘monitor and tune’ so only been reading the data(in both Arduino ide’s serial monitor and rasp pi’s terminal) after uploading the model.
The output in serial monitor is gibberish (boxes) while in terminal(screen) it is not visible at all. I generated a model for rasp pi with serial read block from support package where data is zero and status port indicates ‘data not available’. Tried all three modes for transmit block: write, print, println, but same results. I programmed a test program in arduino ide with serial.println function which was successfully displayed results in both terminal and display from rasp pi simulink model. I’ve successfully implemented basic test models like ‘led blink’ in simulink for arduino so my inference is that the problem is only with serial transmit block and its generated code.
My aim is to establish bidirectional serial communication between Raspberry pi and arduino nano, to exchange multiple values simultaneously(probably having different data types) in an array and separate them for their intended use.I’m using arduino nano(ch340) and implementing serial communication with the Raspberry Pi 4B.
