The total number of Bounding boxes from (Confusion matrix and saved text files)

[greenyjwk]

Hello @glenn-jocher

I have a quick question regarding saved texts(using --save-txt) and the confusion matrix from YOLO v5. I counted all the rows(bounding boxes) throughout all the text files under /labels. However, the total number of bounding boxes(the total number of rows) is less than the total sum of elements in the confusion matrix(TP + FP + FN).

I checked if the confusion matrix has a more strict NMS, but it doesn't look like it. By any chance, do you know why the total number of predictions (bounding box) from the confusion matrix is less than the total number of bounding boxes from txt files(under labels directory)

Thank you.
