imcrop not working for tiff
Hi, i want to crop several .tiff pics so i wrote below code but it dosnt work for .tiff files. it works for .png .jepg . i used imshow it shows nothing for .tiff files.
clc;
clear all;
address=’D:alluni things1-mastermaster project6-Data1-pics1-main2L2-E5′;
filenames=dir(fullfile(address,’*.tiff’));
for n=1:numel(filenames)
fullname=fullfile(address,filenames(n).name);
t1=imread(fullname);
info = imfinfo(fullname);
t2=imcrop(t1,[10, 10, 1000, 950]);
t3=size(t2);
imwrite(t2,fullname);

Keyword search doesnt work for applications in Software Center
MCM (SCCM) 2403
it seems that searching for keywords (set for application in Software Center) seems to be broken in our environment
If i add “abcxyz” to an application as keyword it could not be found via Software Center but if i add it the localized description the application could be found
Any ideas here?

Automatically select drop down list option based on value of other cell
Hi all
I have a column with cells that are populated from a drop down list. I would like one of the list options to be populated auotmatically based on the value of another cell but I am not sure if this is possible.
I would usually use an IF formula for this but can’t with a drop down list as the cells are restricted to the list options so no formla can be added to them. Is there another way to do it?
Thank you

Conditional access issue with app exclusion.
Hi,
We have a conditional access policy (Grant) with some controls and a few apps excluded. The exclusion does not work. The “What if” tool shows everything correctly, but the user is still affected by the policy even when trying to use an excluded app. Sign-in logs show that the policy was triggered as well. Has anyone experienced something like this?

Getting local admins from all PCs
Hello,
I am new to power shell scripting and i got a task where i need to restive all the users that have local admins on their devices.
Any help?
I managed to create a script but i got errors on all users.
This is the script:
#Get Current Computer Name
$computer = $env:computername
#Get Current UserName
$CurrentUser = whoami
#Get User’s Local Group Membership
$CurrentUserGroups = whoami /groups
#Check if current user is a member of the Local Admins group
$CurrentUserAdmin = $CurrentUserGroups -like “*S-1-5-32-544*”
#If user is an admin
if ($CurrentUserAdmin) {
$body = ConvertTo-JSON @{Device = $computer; User = $CurrentUser; IsAdmin = ‘true’}
#Start Flow
Invoke-RestMethod -uri $URI -Method Post -body $body -ContentType ‘application/json’

How to run two simulink models in parallel?
Hello everyone,
I am working with a 3DOF model of a commercial airplane in MatLab/Simulink. This model contains the state propagator and the autopilot. I would like to train an RL agent using the outputs of this model. The problem is that the environment for the RL application contains an exact copy of the state propagator of the 3DOF model. How can I use two of these systems without conflicting with the goto/from blocks and the signal name?

Apps detected as Trojan by Microsoft Defender: Opinion require
Hi,
Last time, my apps was detected as malware by Microsoft Defender (MD). But at that time, we just submit the file for analysis and then MD no longer detect my apps as malware after the ticket close.
However, for my new revamped application from previous version, the analysis failed and tell me that my apps contained malware. It is a VPN application that alter the virtual network for tun interface.
Any thoughts or approach that I can take from here until I MD remove the false detection?

Stream Moves to Intelligent Versioning
In a change designed to reduce the consumption of storage quota, Stream video versions are no longer being generated for non-video updates such as changes to video metadata. Anything that alters the video content, like trimming some seconds from the start or end of a video, will create a new version. It seems like a perfectly reasonable change to make that might help SharePoint storage not be consumed quite so quickly.

How to create view joining two table of similar records without duplicating.
Hi All,
Hope all are doing great. I have a small query regarding the Join function to create view. I have two table in which table 1 is having 40k records and table 2 is having 40k records. But when i am joining the both to create view, it is showing 47k records. Please note that i am combining table using two common column in both, one is “Calendar_Date” and one is “Personal_ID”. In some cases few Personal ID has duplicate records for each month. So while creating the view the, these duplicate records gets multiplied . Hence the total records exceeds 47k. How to make it same 40k records which i am having in each table.
Any help would be highly appreciated.
Regards,
Sagar

Save a stack of 16-bit images to one TIFF file
Hi,
I would like to save a stack (in this case 150) of uint16 grayscale images to a single TIFF-file. First I tried pass over the 3D-array (the third dimension are the individual images) to imwrite, but it complained "Writing TIFFs with 150 components is not supported with IMWRITE. Use Tiff instead. ". I tried this (imgdata is my 3D-array of images):
imgdata = uint16(imgdata);
tagstruct.ImageLength = size(imgdata,1);
tagstruct.ImageWidth = size(imgdata,2);
tagstruct.Photometric = Tiff.Photometric.MinIsBlack;
tagstruct.BitsPerSample = 16;
tagstruct.SamplesPerPixel = 1;
tagstruct.PlanarConfiguration = Tiff.PlanarConfiguration.Chunky;
tagstruct.Software = ‘MATLAB’;
tagstruct.Compression = 1;
t = Tiff(path,’w’);
setTag(t,tagstruct);
write(t,imgdata);
I got the error message "SamplesPerPixel is 1, but the number of image planes provided was 150.", so write() interprets the third dimension as the samples per pixel, which is not what I want. Samples per Pixel needs to be 1, as I have grayscale images.
After that, I also tried it with the "append" option and a loop over the images (with the same tagstruct as above)
t = Tiff(path,’a’);
setTag(t,tagstruct);
numberOfImages = size(imgdata,3);
for n=1:numberOfImages
currentImage = squeeze(imgdata(:,:,n));
write(t,currentImage);
end
close(t);
It runs without errors and the file size of the uncompressed file is exactly what I would expect, so I think the data is in the file. But I can’t open the file in any other software than matlab. Irfanview, imageJ, Windows image viewer all show just the first image of the stack.
Any ideas what’s wrong? Thanks.Hi,

Any ideas what’s wrong? Thanks. Hi,
I would like to save a stack (in this case 150) of uint16 grayscale images to a single TIFF-file. First I tried pass over the 3D-array (the third dimension are the individual images) to imwrite, but it complained "Writing TIFFs with 150 components is not supported with IMWRITE. Use Tiff instead. ". I tried this (imgdata is my 3D-array of images):
imgdata = uint16(imgdata);
tagstruct.ImageLength = size(imgdata,1);
tagstruct.ImageWidth = size(imgdata,2);
tagstruct.Photometric = Tiff.Photometric.MinIsBlack;
tagstruct.BitsPerSample = 16;
tagstruct.SamplesPerPixel = 1;
tagstruct.PlanarConfiguration = Tiff.PlanarConfiguration.Chunky;
tagstruct.Software = ‘MATLAB’;
tagstruct.Compression = 1;
t = Tiff(path,’w’);
setTag(t,tagstruct);
write(t,imgdata);
I got the error message "SamplesPerPixel is 1, but the number of image planes provided was 150.", so write() interprets the third dimension as the samples per pixel, which is not what I want. Samples per Pixel needs to be 1, as I have grayscale images.
After that, I also tried it with the "append" option and a loop over the images (with the same tagstruct as above)
t = Tiff(path,’a’);
setTag(t,tagstruct);
numberOfImages = size(imgdata,3);
for n=1:numberOfImages
currentImage = squeeze(imgdata(:,:,n));
write(t,currentImage);
end
close(t);
It runs without errors and the file size of the uncompressed file is exactly what I would expect, so I think the data is in the file. But I can’t open the file in any other software than matlab. Irfanview, imageJ, Windows image viewer all show just the first image of the stack.
Any ideas what’s wrong? Thanks. tif, tiff, multipage tiff, imwrite MATLAB Answers — New Questions

Remove exponentials with positive argument in symbolic MATLAB
Hello!
I am using symbolic MATLAB to obtain an expression of the form:
Where are some complicated expresions of other variables. To avoid problems with numeric evaluation, I would like to express the expression in the form:
Is there a way to easily implement that on MATLAB?

Security Baselines
Hi, I’m having an issue after enabling the baseline securities. When we connect our laptop to the docking station via the Thunderbolt port, the peripherals (mouse, keyboard, and network connection) get blocked.
We suspected the policy “Disable new DMA devices when this computer is locked,” but disabling it didn’t help.
Does any body have any idea, which policy it might be blocking the peripherals ? this is a headache to find.
