how can i save the image and roi to train classifier

i use this code

    axes(handles.axes1)
h=imrect;
position = round(wait(h));
curImg=1;
I=imread(strcat(pathname, filename{k}));
[rows, columns, numberOfColorBands] = size(I);
% Crop image
I2 = imcrop(I,position);
figure;
imshow(I2);
 data(curImg).imageFilename = I;
 data(curImg).objectBoundingBoxes = position;
 curImg = curImg + 1;

I select roi than i extract the position and i save the pathname and the position of the roi, when i use the struct data to train classifier it dosen't work, here is the code:

    trainCascadeObjectDetector('Detector.xml',data,negativeFolder,'FalseAlarmRate',0.2,'NumCascadeStages',5);

i get struct with 2 field and 1 column rows are:imageFilename and objectBoundingBoxes.

Try using the Training Image Labeler app.
