I'm collecting a lot of positive images to train the cascade classifier and so I have some doubts:
1 - I'm trying to recognize object that has 2 different formats, so it's better create 2 cascade's xml to each different format or 1 cascade's xml with a lot of 2 images formats ?
2 - The color of positive samples can influence in the object detection ? Is it better that the positive samples are in greyscale ?
Thanks for your help !
