skimage2.exposure.adjust_log#

skimage2.exposure.adjust_log(image, gain=1, inv=False)[source]#

Performs Logarithmic correction on the input image.

This function transforms the input image pixelwise according to the equation O = gain*log(1 + I) after scaling each pixel to the range 0 to 1. For inverse logarithmic correction, the equation is O = gain*(2**I - 1).

Parameters:
imagendarray

Input image.

gainfloat, optional

The constant multiplier. Default value is 1.

invfloat, optional

If True, it performs inverse logarithmic correction, else correction will be logarithmic. Defaults to False.

Returns:
outndarray

Logarithm corrected output image.
