i did all but still hangs evrey thing is acc to the tuto. what to dio

2013-05-08 07:05:10 -0500 asked a question Haar Training not going smoothly. Please suggest what to Do?

MY positive samples are 50 with 33X40 i.e face image passport size.All positive image is my ROI. so my Descriptive file looks like {pos\1.png 1 0 0 33 40 } & all 50 are same. Negative samples are 500.

My first step simple i create vec file from positive descriptive file. First command :- { opencv_createsamples.exe -info pos.dat -vec samples.vec -w 33 -h 40 } And my output is Samples.vec is Vector file of positive samples.

Then my Second step to run haartraining is {opencv_haartraining.exe -data haarcascade -vec samples.vec -bg negatives.dat -nstages 20 -nsplits 2 -minhitrate 0.999 -maxfalsealarm 0.5 -npos 5/50 -nneg 50/500 -w 33 -h 40 -nonsym -mem 4000 -mode ALL} --Note -npos i use one time 5 and one time 50 same in case of -nneg 50 and 500 also. for running but with this command it runs upto 3 satges then hang for many days even weeks.

kindly help me where i am wrong?I am working on training from jan but same problems i change machine now using i7,12gb ram, i siwtch on ubantu xp all but same problems kindally tell me where i am wrong. My all work stops only of this? I also go by this tuto :- http://note.sonots.com/SciSoftware/haartraining.html But same problems. i change open cv all types, os nd myy my best done know.

2013-04-01 00:31:02 -0500 asked a question Haar Training hang after few stages.

I am doing haar training for object detection, first 10 stages goes very fast after 10th stages. it will hangs more than 9 days.i am using i7-12gb-ram.still slow. Pos samples 494 and negative samples 2500.

MY steps for haar training :-

1. Create training samples from one { createsamples -img face.png -num 10 -bg negatives.dat -vec samples.vec -maxxangle 0.6 -maxyangle 0 -maxzangle 0.3 -maxidev 100 -bgcolor 0 -bgthresh 0 -w 20 -h 20}

2*Create training samples from some* {opencv_createsamples -info samples.dat -vec samples.vec -w 20 -h 20]

3. Create test samples {opencv_createsamples -img face.png -num 10 -bg negatives.dat -info test.dat -maxxangle 0.6 -maxyangle 0 -maxzangle 0.3 -maxidev 100 -bgcolor 0 -bgthresh 0}

4. Show images {opencv_createsamples -vec samples.vec -w 20 -h 20}

5 haar training {Opencv_haartraining -data haarcascade -vec samples.vec -bg negatives.dat -nstages 20 -nsplits 2 -minhitrate 0.999 -maxfalsealarm 0.5 -npos 7000 -nneg 3019 -w 20 -h 20 -nonsym -mem 512 -mode ALL}
