Hello everyone, I am running object detector in Matlab ... after running detector on test image the result looks like this :
But I want my program to show also names for each class ... for example if there is an airplane i want to see the confidence and name airplane also...
Here is my code which runs detector on one of the images :
I = imread(testDataTbl.imageFilename{94});
I = imresize(I,inputSize(1:2));
[bboxes,scores] = detect(detector,I);
I = insertObjectAnnotation(I,'rectangle',bboxes,scores);
figure
imshow(I)

FIrst (somehow) convert each score into its corresponding class name.
Then when you call insertObjectAnnotation pass the class name as the fourth parameter (where you are passing scores now)

Any object detector that supports detection multple classes will return the labels as a third output argument:
[bboxes,scores,labels] = detect(detector,I);
You can create a string with the label and score:
str = string(labels) + ": " + scores;
I = insertObjectAnnotation(I,'rectangle',bboxes,str);
