Need help on trainCascade usage on mine

Hi All, I am trying to detect the banana using traincascade approach. positive sample-40(40*50 using createsample.exe )

+ive desc file looks like:

rawdata/1.bmp 1 180 154 494 161 rawdata/2.bmp 1 247 154 349 175 rawdata/3.bmp 1 133 118 488 141

1.CreateSamples

createsamples -img Positive\rawdata\2.bmp -num 50 -bg bg.txt -vec data\positive2.vec -maxxangle 1.1 -maxyangle 1.1 -maxzangle 0.5 -maxidev 40 -bgcolor 0 -bgthresh 0 -w 24 -h 24

where i am passing 40 diff single +ive sample and creating 50*40 =2000 samples

Negative 600 imags: -ive desc looks like: bg.txt :

Negative/1.bmp Negative/2.bmp Negative/3.bmp

after that using the mergevector.cpp.

using command mergevec pos-neg.txt pos-neg.vec -w 24 -h 24

so my pos-neg.vec is having size of 2.19mb.

2.for Training i am using TrainCascade.exe -data Result -vec pos-neg.vec -bg bg.txt -numPos 1500 -numNeg 600 -w 24 -h 24 -featureType LBP -minHitRate 0.999 -maxFalseAlarmRate 0.5 -mode ALL -precalcValBufSize 1024 -precalcIdxBufSize 1024

My console O/p of training:

Need help on trainCascade usage of mine

Hi All, I am trying to detect the banana using traincascade approach. approach. positive sample-40(40*50 using createsample.exe )

+ive desc file looks like:

rawdata/3.bmp 1 133 118 488 141
 
1.CreateSamples

Used the CreateSamples utility

createsamples -img Positive\rawdata\2.bmp -num 50 -bg bg.txt -vec data\positive2.vec -maxxangle 1.1 -maxyangle 1.1 -maxzangle 0.5 -maxidev 40 -bgcolor 0 -bgthresh 0 -w 24 -h 24

where i am passing 40 diff single +ive sample and creating 50*40 =2000 = 2000 samples

Negative 600 imags: images and -ive desc looks like: like:

bg.txt :

Negative/1.bmp
Negative/2.bmp
Negative/3.bmp
Negative/3.bmp

after that using the mergevector.cpp.

using command 

mergevec pos-neg.txt pos-neg.vec -w 24 -h 24
