NEQR, INEQR, GQIR currently work for grayscale images only.

Image representation methods, NEQR (implemented), INEQR (PR #46 ), and GQIR (to be implemented), currently support q = 8 for a grayscale color range of 2^8 = 256 (i.e., maximum color intensity = 255, range [0, 255]).

To expand implementations for binary and colored images, q value needs to account for variable values for different images.

  1. Binary image, q = 2
  2. Colored image, q = 24 (3 RGB channels of q = 8 each)

Different representations will need to be added to the pipeline for RGB images. The above-mentioned QIR methods inherently support grayscale images only.

Currently, I believe it is better to have different implementations for grayscale and RGB images rather than making changes to the existing ones.
