BIOP Lookup Tables

Purpose

Having LUTs to handle display of images with more than 3 channels. Visit Color Image Processing page to know more about LUTs.

Details

Classical color space are RGB and CMY. Expressed as RGB value, CMY are equal combination of 2 components of RGB, ie Cyan is obtained by combining Green and Blue in equal proportion.

RGB colorspace CMY colorspace

Here, we propose to use 6 LUTs, which are obtained by combining Red Green and Blue, by two, in different proportion.

6 LUTs combination

On 3 channels image

3 channels each in Grays levels

RGB

3 channels image, in Red Green Blue and Merge

CMY

3 channels image, in Cyan Magenta and Yellow

On 4 (to 6) channels image

4 channels image, each in Grays levels

Appropriate BIOP-LUTs selection

4 channels image, biop luts good choice

Unappropriate BIOP-LUTs selection

4 channels image, biop luts poor choice

Here, channels 2 and 3 are tubular structure and it’s difficult to distinguish them if both are greenish.

Macro Language
