for object detection there are four text files in the ImageSets/Main folder.
A good ratio of all images seems to be train 80%, val 10% and test 10% . Those files are clear to me, but not the trainval file. Which images should be selected inside this file?
Is it reasonable to select one or more images in several text files not only one? E.g. use the same images for val and test.
Thanks in advance,
