I'm want to detect a bed in room. One may be edge detection or may be region area defining. Please, help me to start with this.

Is there any refrence manual for C?

any other parameter which i will check

PLS COMMENT THAT ANY PARAMETER ON WHICH I WILL NOT ABLE TO CONSIDER

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

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.

Thanks Lee & Steven

Thanks Steven.....but can you provided some tutorial with example.This one i studied.

Thanks Lee....is there any properly explained tutorial for train cascade.

same problems any answer plssssssssssssssssssss

tell me some other thing help.....and methods is right or wrong

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}

Tree Classifier Stage +---+---+---+---+---+---+---+---+---+---+---+ | 0| 1| 2| 3| 4| 5| 6| 7| 8| 9| 10| +---+---+---+---+---+---+---+---+---+-- 0---1---2---3---4---5---6---7---8---9--10 Parent node: 10

* 1 cluster * POS: 90 90 1.000000

And other one like this aftr 16th stage

IS IT WORK WITH WITH THIS FEW SAMPLES. JUST FOR PRACTICE HOW TO DO HAAR TRAINING.

Thanks a lot Man.

i need a discussion on haar training,

I AM USING OPEN CV 2.4.3,ECLIPSE C/CPP? MY QUESTION IS- WHERE,HOW,TO CERATE TRAINCASCASDE, (http://note.sonots.com/SciSoftware/haartraining.html) i go thru this links,but doesnot clear.

kindly help to give some links in theses

Thanks & Do you any idea about for other tutorial which is in more descriptive?

MAIN TERMS, STEPS NOTATION USED FOR THIS, WHERE AND HOW APPLY. SOFTWARE, TOOL, ETC.. AM ZERO ABOUT THIS. PLS HELP.

what syntax should i use.for particle filter.

or any other solution... is particle filter have any connection with blob tracking. ...... in opencv 2.1 used particle filter used as Cvcondensation but in 2.4.3 no such function for particle filter.........

dateay raaj ki jai ho

??????????

WELL MY QUESTION IS LIKE THIS I HAVE TO DETECT A BED IN A ROOM,IT MAY BE SQUARE OR RECTANGLE. I WANT TO DETECT WITH VIDEO CAMERA .BUT FIRSTLY I HAVE TO GIVE BASIC BED MODEL AND THIS MODEL MATCH WITH PATTERN RECOGNITION . >>>>BUT HOW CAN I MAKE BASIC MODEL WITH SHAPE AND SIZE?

@Michael Burdinov thanks for atleast replying.........if i go with pattern recognition..how it will help some idea.
