Detailed Description
Computes the natural logarithm of each pixel values of a source image and places the results in the destination image; for in-place flavors - in the same image.
This is the QVision processing block for the IPP function ippiLn_32f_C1R. The input and output properties of this block will correspond to the input and output parameters of that function. See Intel's IPP documentation for further info about them.
These are the input and output properties of this block:
- Parameters:
-
| qvimage_pSrc | Image corresponding to the data buffer pointer pSrc and step number srcStep variables in the IPP function |
| qvimage_pDst | Image corresponding to the data buffer pointer pDst and step number dstStep variables in the IPP function |
| destROIOffset | Pointer to destination ROI. See section Destination ROI pointer for more info about this parameter. |
