2016-10-28 12:56:34 -0600 | asked a question | OpenCV traincascade stuck on Stage 4 Hi! I am trying to train a cascade classifier to detect a logo, and I keep getting stuck on stages. I started off with 200 pos and 700 negative samples, and this wouldn't even train past stage 2 (which also stopped on the same POS count line below, but for stage 2). When I found more samples (2600 pos and 5000 neg), I made it to Stage 4 before the infinite loop started again. It is usually stuck on this line: Here is the command I am running: Does it matter that I am using LBP? Should I change the number of positive and negative samples? What is the ideal ratio of pos to neg? I know CPU isn't a concern, as I am running this training on an AMI. Any other tips or fixes? Thanks! |
