Can we impose geometry constraints on fisheye lens calibration and rectification?
Assuming that the distorted lines generated by fisheye projection should be straight after rectification, can we use deep neural network to impose explicit geometry constraints onto processes of the fisheye lens calibration and the distorted image rectification?Assuming that the distorted lines generated by fisheye projection should be straight after rectification, can we use deep neural network to impose explicit geometry constraints onto processes of the fisheye lens calibration and the distorted image rectification?

Configuring 2×2 Antenna Setup with 2 CSI-RS Ports in MATLAB’s 5G Toolbox for CQI Reporting Test Compliance
I am working on implementing the table from TS138.101 Table 6.2.2.1.1.1-1: CQI reporting definition test using MATLAB’s 5G toolbox example, "NR PDSCH Throughput Using Channel State Information Feedback". The table specifies that the number of CSI-RS ports (X) should be 2, with an antenna configuration of 2×2.
In the MATLAB example, setting the panel dimensions to 2×2 results in NTxAnt becoming 8, which corresponds to the number of CSI-RS ports. However, according to the test table, to set the number of CSI-RS ports (X) to 2, the row number should be set to 3.

I am new with Matlab and I would like to know why I am not reading a cell array as I saved it. i.e. I have a cell of arrays (3834×1) and I saved it as csv file.
writecell(X_train_past, …
strcat(train_data_path, ‘past_features.csv’), …
"Delimiter",";")
However, when reading the cell I got a cell of 926×864, totally different of the saved cell array. Is there any way to get the same shape when reading a cell as it was writen ?
opts = detectImportOptions(test_path);
opts.LineEnding = ‘n’;
C = readcell(test_path,opts);
Thanks a lot in advance,

Do graphs work in Custom Components?
I built a custom component (first time I’ve tried this) containing two Axes objects as well as some text fields. Here’s a picture. I’ve been having some problems.
1. These graphs appear one size in the editor, and larger when an instance of my component is inserted into my app. (Compare the relative size of the graph to the text fields, in the picture above in the picture below.)
2. Some fraction of the time, when I run the app, the Axes objects don’t appear at all, although the other parts of the custom component do.
Is this a known bug? Is this usage of Axes objects a hopeless mess? Or is there some way I can tweak it to get around this problem.
