Bounding Box Not Drawn/Some Variables Are Empty
17 views (last 30 days)
Me here again,
I managed based on some advice but the advice only got me thus far as i 've tried google and this community as well but i am grateful!
What I am trying to do is draw the yellow box around the object of interest and it's challenging!
Can someone tell me why these variables are empty when the data is loading and traning without error please?
please point me in the right direction so that i can get this sorted!!
Thank you in adavance for acknowledging me!
I will upload and image of the empty variables and dispense my code!
Please see screen shot for details
%% Training the R-CNN detector. Training can take a few minutes to complete.
% Loading .MAT file, the ground truths and the Network layers
net = alexnet
%load('gimlab.mat', 'gTruth', 'net');
rcnn = trainRCNNObjectDetector(gTruth, netTransfer, opts, 'NegativeOverlapRange', [0 0.3])
%% Testing the R-CNN detector on a test image.
img = imread('Gun00011.jpg');
[bbox, score, label] = detect(rcnn, img, 'MiniBatchSize', 32);
%% Displaying strongest detection result.
[score, idx] = max(score);
bbox = bbox(idx, :);
annotation = sprintf('%s: (Confidence = %f)', label(idx), score);
detectedImg = insertObjectAnnotation(img,'rectangle', bbox, annotation);

Even though you have loaded and trained on the data without error, the reason your bounding box shows empty is because during testing the RCNN detector is unable to find the object (matching class) in the image and hence is does not draw any bounding box(therefore, bbox is empty matrix).

I'm in the same situation. have you understood the problem so far?
