Log Transformation

Log transformation is usually applied on Fourier transformed images. I have used the same green bee-eater image and tried multiple constants.

Command Line

Original image:

Constant = 900:

$loomis -command log_transformation -levels 900 testdata/green-bee-eater-grayscale.jpg

Constant = 100:

$loomis -command log_transformation -levels 100 testdata/green-bee-eater-grayscale.jpg

Constant = 50:

$loomis -command log_transformation -levels 50 testdata/green-bee-eater-grayscale.jpg

Library Usage

newImage := pkg.LogTransformation(image, constant)

image is of type image.Image
constant is an integer
