I follow the demo of fast RCNN to study deep learning.
URL : https://www.mathworks.com/help/driving/examples/train-a-deep-learning-vehicle-detector.html
but erros happen.
% Read one of the images.
I = imread(vehicleDataset.imageFilename{10});
% Insert the ROI labels.
I = insertShape(I, 'Rectangle', vehicleDataset.vehicle{10});
errors:
>> insertShape(img1, 'Rectangle', vehicleDataset.vehicle{1})
Error using vision.ShapeInserter
The specified superclass 'matlab.system.SystemAdaptorSFun' contains a parse error, cannot be found on MATLAB's
search path, or is shadowed by another file with the same name.
Error in insertShape>createShapeInserter_sim (line 792)
h_ShapeInserter = vision.ShapeInserter('Shape', 'Rectangles', ...
