Parameters
- pSrc
- Pointer to the source image ROI.
- srcStep
- Distance in bytes between starts of consecutive lines in the source image.
- roiSize
- Size of the source ROI in pixels.
- counts
- The computed number of pixels within the given intensity range. An array of 3 values in case of multi-channel data.
- lowerBound
- Lower limit of the intensity range.
- upperBound
- Upper limit of the intensity range.
Description
This function operates with ROI (see Regions of Interest in Intel IPP). This function computes the number of pixels in the image which have intensity values in the range between
lowerBound
and upperBound
(inclusive).In case of a multi-channel image, pixels are counted within intensity range for each color channel separately, and the array
counts
of three resulting values is returned. The alpha channel values, if present, are not processed.Return Values
- ippStsNoErr
- Indicates no error. Any other value indicates an error or a warning.
- ippStsNullPtrErr
- Indicates an error condition ifpSrcpointer isNULL.
- ippStsSizeErr
- Indicates an error condition ifroiSizehas a field with zero or negative value.
- ippStsStepErr
- Indicates an error condition ifsrcStephas a zero or negative value.
- ippStsRangeErr
- Indicates an error condition iflowerBoundexceedsupperBound.
