public void filter(Mat src,
                   Mat dst,
                   int dDepth)
```
    Produce domain transform filtering operation on source image.
    
    Parameters:
    
    src - filtering image with unsigned 8-bit or floating-point 32-bit depth and up to 4 channels.
    
    dst - destination image.
    
    dDepth - optional depth of the output image. dDepth can be set to -1, which will be equivalent to src.depth().
