Hi Guys
i would like to get a help for the following code where i want to have apperance of Bounding boxes in image or video when they are more than only 2 bounding boxes or more in same time for object detection
the code is
% PROCESS
[bboxes, scores, label] = detect(detector,I,'MiniBatchSize', 128);
% Select strongest detection
% New - Find those bounding boxes that surpassed a threshold
T = 0.50; % Define threshold here
idx = scores >= T;
% Retrieve those scores that surpassed the threshold
s = scores(idx);
% Do the same for the labels as well
lbl = label(idx);
bboxes = bboxes(idx, :); % This logic doesn't change
for ii = 1 : size(bboxes, 1)
annotation = sprintf('%s: (Confidence = %f)', lbl(ii), s(ii)); % Change
I = insertObjectAnnotation(I, 'rectangle', bboxes(ii,:), annotation); % New - Choose the right box
end
step(vidPlayer,I);
i = i+1;
end
results = struct2table(results);
release(vidPlayer);

A simple if condition before displaying the annotation will do
if (size(bboxes,1) > 1)
for ii = 1 : size(bboxes, 1)
annotation = sprintf('%s: (Confidence = %f)', lbl(ii), s(ii)); % Change
I = insertObjectAnnotation(I, 'rectangle', bboxes(ii,:), annotation); % New - Choose the right box
end
end

Hi Ajay
this is a really easy solution but could you please tell me that how can I change the Font size of the score value (When an object is detected in the frame than it shows the score value like 97.xx so how can I change the font size of this score value). Currently, it's showing me very small in my detection, Hardly see it.
thanks in advance for answering.
