I think that the best way to export your annotated images from Matlab to python is saving as a hdf5 file.

Hi Oscar Julian Perdomo Charry thank you very much, actually my supervisor wrote this code for me to export it outside matlab

imagefiles = dir('.imageLabelingSession_SessionData\*.png');

nfiles = length(imagefiles); % Number of files found

for ii = 1 : nfiles

currentfilename = imagefiles(ii).name;

currentimage = imread(['.imageLabelingSession_SessionData\' currentfilename]);

% images{ii} = currentimage;

% img = double(imread(['Test\' currentfilename]));

im = imread(['.imageLabelingSession_SessionData\' currentfilename]);

v = im; % imagesc handle

map = colormap;

minv = min(v(:));

maxv = max(v(:));

ncol = size(map,1);

s = round(1+(ncol-1)*(v-minv)/(maxv-minv));

rgb_image = ind2rgb(s,map);

imwrite(rgb_image,['labels\' 'rgb' currentfilename]);

% labels a new directory to save your images

end

If you have your ground truth object in .mat format then you use scipy library in python to load the .mat file.
