LogarithmImage_Deprecated


Computes a natural logarithm of each pixel.

Name Type Range Description
inImage Image Input image
inRoi Region* Region of interest
inScale Real* Scaling factor (default: 255)
inOffset Real 1.0 - Offset factor
inNormalizeZero Bool Specifies whether the output range should be rescaled to start from 0
outImage Image Output image
diagLutProfile Profile Profile depicting the resulting look-up table of the logarithm transform

Only the following inImage pixel formats are supported: int8, uint8, int16, uint16, int32

Applications

Transforms an image in such a way that a quotient on the input image becomes a difference on the output image. This can be useful for dealing with variable illumination.

Hardware Acceleration

This operation supports automatic parallelization for multicore and multiprocessor systems.

Complexity Level

This filter is available on Basic Complexity Level.
