The function cvCopyHist makes a copy of the histogram. If the second histogram pointer dst is null, a new histogram of the same size as src is created. Otherwise, both histograms must have equal types and sizes. Then the function copies the source histogram bins values to destination histogram and sets the same bin values ranges as in src.
