MATLAB: Can we find the original code for MATLAB’s inbuild apps

appsImage Processing ToolboxMATLABregistrationestimator

Hi all, I wish to see the code that has been written for the in-build app: Registration Estimator.

Can anybody help me with this? Thank you!

Look in

fullfile(matlabroot, 'toolbox', 'vision', 'vision')
fullfile(matlabroot, 'toolbox', 'vision', 'vision', '+vision', '+internal', '+detector')

Start from here: https://www.mathworks.com/help/matlab/app-designer.html. Topics are organized from simpler to more complex. The page also has featured examples. For more examples, click the "Examples" tab at the top.

It has been in

fullfile(matlabroot, 'toolbox', 'vision', 'visiondata', 'fasterRCNNVehicleTrainingData.mat')

since R2017a, which was the release that added RCNN. You need the Computer Vision Toolbox for it.
