In this section, image enhancement technique
that is based on logarithm transformation of the
luminance of the pixels in the image. The algorithm
consists of independent steps for luminance
enhancement with dynamic range compression and
contrast enhancement. The luminance enhancement
step considers the maximum color component of the
pixels in the nonlinear transformation with dynamic
range compression based on a logarithmic approach
while the ratios of the original color bands (R, G and
B) are preserved. The proposed steps as follows
