| 2017-05-31 12:34:59 -0600 | commented question | Error at the begining of Training Stage 1 yeah cause i wanted to try training very fast but i am here to learn my friend ;) have you got advices for me ? like i have to crop every positives images ? is there a minimum number ? just to try the training on my debian serv. |
| 2017-05-29 15:29:01 -0600 | commented question | Error at the begining of Training Stage 1 wow 20x20 or 24x24 its a very small size for an image !!! ;) i used 50x50 on my first fail test ! ahah Do i have to create new samples with small positives images to put on large negatives? or the opencv training need to train neg against only small positives with the objet i want to use as "positive object" in ? Are you an expert of that ? I am going to crop all my images but i need to know if there is clues or advices before starting this looooong process ! |
| 2017-05-28 17:22:49 -0600 | commented question | Error at the begining of Training Stage 1 What is your advice for the multiple positive images ? i have to crop a maximum and keep the square ratio ? the same size ? time is not a problem for me, i can run training for days:) so what is your advice for the size of neg and positive images ? |
| 2017-05-28 08:24:51 -0600 | asked a question | Error at the begining of Training Stage 1 Hi guys, i am totally new in our OpenCv community, i am from France so excuse my english if its start to turn crazy ahaha. I started this week end to build a Haar cascade, i work on a window 10, my serv is a Debian machine (4G Ram, slow machine). i downloaded 1920 images in my neg file, i did the bg.txt (here "bgdef.txt") i created samples with my Pos image (1920 too) (only one pos image that i copied into Neg images with : opencv_createsamples -img voiture5050.jpg -bg bgdef.txt -info info/info.lst -pngoutput info -maxxangle 0.5 -maxyangle -0.5 -maxzangle 0.5 -num 1920 also my positives.vec with : opencv_createsamples -info info/info.lst -num 1920 -w 20 -h 20 -vec positives.vec opencv_traincascade -data data -vec positives.vec -bg bgdef.txt -numPos 1920 -numNeg 1900 -numStages 10 -w 20 -h 20 when i start my training with : opencv_traincascade -data data -vec positives.vec -bg bgdef.txt -numPos 1920 -numNeg 1900 -numStages 10 -w 20 -h 20 then its start training... Stage 0 complete in 37 min... then Bam Stage 1 it's stop with the message : ===== TRAINING 1-stage ===== BEGIN POS current samplOpenCV Error: Bad argument (Can not get new positive sample.
