| dstRoiSize | Destination image ROI size. | |
| dstStep | Destination buffer step size (width of the buffer in bytes). | |
| maskSize | Specifies the size of a mask used in calculations. | |
| pDst | Pointer to a location in a destination buffer. | |
| pSrc | Pointer to a location in a source buffer. | |
| srcStep | Source buffer step size (width of the buffer in bytes). |
These functions step through an ROI in a source buffer, replace each source pixel value with the median value of all pixels in the area defined by the vertical mask, and write the filtered data to a destination buffer.
The functions remove noise without decreasing image brightness, as averaging filters do.
The functions can use arbitrary vertical mask sizes.
