Thanks! I tried this and got it working.
I wanted to test auto cropping images with irfanview. It works great. I ran it on every images in a folder, then passed the array of size and location to irfanview cmd and had thumbs of all the objects generated.
I have a question about the 3 yolo files, weights, cfg, and the classes i believe, the txt file. I went to the yolo website and seen I can get different weights and cfg files. Are these more object sets? Sorry if such a noob question, just exploring my options for existing weight files already made and if different objects can be detected with these weight files than the one you linked to. Looks like the class file here has 80 objects it can detect.
I need to read more, but any direction you can point is helpful, thanks.
