Z-Score Method

This chapter introduces an image enhancement approach utilizing the Z-score for images captured under hazy and non-uniform illumination conditions, with a focus on applications in multi-media. The presented approach involves estimating scene transmission through a Z-score based weighting function and utilizing global atmospheric light for image dehazing. In contrast, the method equalizes the illumination channel by employing the Z-score weighting function for non-uniformly illuminated images. The chapter includes a comparative analysis to demonstrate the quantitative and visual effectiveness of the Z-score approach.
