I am working on a program which detects cans from a picture. I am using a cascade classifier to do that. To improve its quality I need to provide more positive samples. I have made many photos of cans from different angles and in different light settings.
Long story short, I have around 100 photos (around 5 cans in each) and I need to crop all those cans into separate images. Cropping each one and exporting in GIMP is really slow. Is there any tool you could recommend to make this faster?
Thanks a lot in advance and sorry for my English!
