Gamma correction 2.2
WebWhen gamma correction is applied, the pixel values of images with different exposures are corrected to the same range. Consequently, it is easier for the network to determine if two images are structurally different because of over-exposure or under-exposure, allowing the network to retain more details on the fusion images. WebGamma describes the relationship between a color value and its brightness on a particular device. For images described in an RGB color space to appear visually correct, the …
