I trained a faster rcnn object detector using the example code. the training process sucessfully finished but i came up with this error.when this code runs,
___________________________________
I = imread('image1.png');
% Run the detector.
[bboxes, scores] = detect(detector, I);
% Annotate detections in the image.
I = insertObjectAnnotation(I, 'rectangle', bboxes, scores);
figure
imshow(I)
....
then this error came
Error using insertObjectAnnotation
Expected LABEL to be nonempty.
Error in insertObjectAnnotation
Error in insertObjectAnnotation
Error in insertObjectAnnotation
Error in t27_trainFasterrcnn (line 139)
I = insertObjectAnnotation(I, 'rectangle', bboxes, scores);
please help me.

Same issue - was this resolved? Can this be solved by increasing the number of epochs used in the model?

The insertAnnotation function excepts labels to be passed as na arguments.
Try cloading labels using
[bboxes,scores,labels] = detect(detector,I)
Then call insertAnnotation function using
detectedI = insertObjectAnnotation(I,'Rectangle',bboxes,cellstr(labels));
Refer to this link for an example: Object detection using faster R CNN
