Description

Hi all,

the code is here:

float range[]= { 0, 256} ;
const float*histRange =range;

bool uniform = true; bool accumulate = false;
/// Compute the histograms:
calcHist(&c1,1,0,Mat(),hist,1,&histSize,&histRange,uniform, accumulate);

I try different size gray(8 bit) image to calcuate histogram, but i find some throw expection at big picture.The attachments is picture file and catch error picture.
