We propose an effective and robust method to enhance the color image under low or non-uniform lighting conditions that models global and local adaptation of the human visual system. The main idea is that we preserve the discontinuities of the local luminance with combined most significant bit and an adaptive smoothing mask. The local contrast enhancement adjusts the intensity of each pixel based on...
As the angle and intensity of light may change in practical cases, it is difficult to measure the illumination of an image. Taking into account the characteristics of the image illumination conditions, we propose a new method based on bilateral-filtering algorithm to enhance the illumination invariant from the face image, then estimate the compensation image by dividing the original image, and finally...
