How can I compare two histograms in OpenCV c++?
I am tying to compare two histograms, but it gives error. Here I have given my code, histogram file and error message.
Histogram file 3*5 matrix(output_test.txt):
1 2 3 4 5
5 2 1 4 2
2 1 2 4 2
code:
Code:
int main(..........)
{
................................................
Mat first_histogram(1,feature_vector_size, CV_32F);
Mat second_histogram(1,feature_vector_size, CV_32F);
for(i=0;i<count_row;i++)
{
for(j=0;j<count_row;j++)
{
if(i==j)
{
comparision_feature[i][j]=0.0;
}
else
{
l=0;
for(k=0;k<feature_vector_size;k++)
{
first_histogram.at <float>(l,k)=read_feature[i][k];
second_histogram.at <float>(l,k)=read_feature[j][k];
}
temp_distance=compareHist(first_histogram,second_histogram,CV_COMP_CORREL);//error message
comparision_feature[i][j]=temp_distance;
}
}
}
Error message: error LNK2019: unresolved external symbol "double __cdecl cv::compareHist(class cv::Mat const &,class cv::Mat const &,int)" (?compareHist@cv@@YANABVMat@1@0H@Z) Is there anybody who can help in this regard?

Anyway, I have solved the problem. I include "opencv_imgproc220d.lib" in additional library dependencies in VC++2010.
