Color Constancy Filter

Description: Color constancy is the ability of the human visual system that ensures the perception of the color of objects to remain relatively constant under varying illumination conditions. A color constancy filter would basically be applied on images with various degrees of damage to restore original colors as close as possible.

Applications:

  • Image restoring filter by photographers.
  • Pre-processing step for computer vision algorithms that utilizes image colors.

Outcome: Low-level image statistics Grey Edge algorithm was implemented alongside with Weighted Grey Edge improvement.
