how can I save/load vision.ForegroundDetector object?
显示 更早的评论
This was already asked here http://www.mathworks.com/matlabcentral/answers/158594-foreground-detector-how-do-i-save-load-an-existing-background-model, but the solution doesn't work for me on R2014a or R2014b. Here is what I did:
clear all
% init model
detector = vision.ForegroundDetector();
% train model
image = imread ('frame0.png');
step(detector, image);
image = imread ('frame1.png');
step(detector, image);
% save the trained model
feature('SystemObjectsFullSaveLoad',1);
save('detector.mat', 'detector');
% clear and load the trained model
clear all
load('detector.mat');
% try to use
image = imread ('frame0.png');
mask = step(detector, image); % this crashes matlab
At the last line, Matlab crashes with a segmentation fault. Is it a bug or is there some other function to call prior to saving?

Hi,
I tried on both R2014a and R2014b and I couldn't reproduce the segmentation fault.
Do you have the stack trace from the seg fault? That might help determine where the problem is coming from.

Also, can you post the images you used (frame0,frame1)? They might be required to reproduce the issue.

Any serious problem like a segmentation fault where the entire MATLAB development shuts down unexpectedly should be reported to the Mathworks.
