gray_histo(Regions, Image : : : AbsoluteHisto, RelativeHisto) 计算图像Image内区域Regions的绝对相对灰度直方图AbsoluteHisto, RelativeHisto, 这两个直方图都是256个值的元组,从0开始包含图像的各个灰度值的出现频率。 AbsoluteHisto表示整数灰度值的绝对频率, RelativeHisto表示相对频率,如绝对频率除以图像面积作为浮点...
gray_histo (Domain, Image1, AbsoluteHisto, RelativeHisto)*计算直方图:指定区域*为区域内的图像计算灰度值的绝对和相对直方图*参数1:要计算直方图的区域*参数2:要计算其灰度值分布的图像*参数3:是指图像内0-255灰度值出现的次数-->直方图*参数4:将上面的出现次数转化为频率,总合为1 histo_to_thresh (Absolute...

If the Image has discrete gray values the size of a bin is computed with . Since the accuracy of the histogram Histo can be adjusted with NumBins, the calculation of the gray value histogram with gray_histo_range is most useful for images of type 'real' and images of type 'integer', ...
gray_histocan be executed on OpenCL devices for byte, int1, directional and cyclic images if the OpenCL device supports the cl_khr_local_int32_base_atomics and cl_khr_global_int32_base_atomics extensions (which are optional in OpenCL 1.0). Unlike most other HALCON operators,gray_histocan...

in the histogramHisto. IfBinSize<1some classes are not assigned by any gray value, e.g., forBinSize=0.5the first gray value is assigned to the first bin and the second gray value is assigned to the third bin. The histogramHistoshows some gaps, which resembles the structure of a comb....
