`skimage.exposure.exposure:adjust_log`

source: /dev/scikit-image/src/skimage/exposure/exposure.py :691

Signature

def adjust_log ( image , gain = 1 , inv = False )

Summary

Performs Logarithmic correction on the input image.

Extended Summary

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

image : ndarray: Input image.
gain : float, optional: The constant multiplier. Default value is 1.
inv : float, optional: If True, it performs inverse logarithmic correction, else correction will be logarithmic. Defaults to False.

Returns

out : ndarray: Logarithm corrected output image.
