Refined Measurement of Digital Image Texture Loss

Article: Refined Measurement of Digital Image Texture Loss

Matlab source code to compute the measure of texture loss based on images of dead-leaves type of test targets. The method includes correction for image noise and shading/non-uniformity, as described in,
P. D. Burns, Refined Measurement of Digital Image Texture Loss, Proc. SPIE vol. 8293, Image Quality and System Performance IX, 2013,86530H, 2013

The method was also used in the evaluation of JPEG2000 image  compression in,

Refinements: I am distributing this code primarily for those who are familiar to adapting Matlab for their own applications. Depending on interest expressed, I can include more flexible parameter selection, data checking and other refinements that I would normally include as part of a complete image-based tool. Also, please contact me if you are interested in an executable version of this method as part of a console-type programme. I have fun with this sort of thing too.
