Contrasting loss
WebContrast is defined as the difference in light intensity between the image and the adjacent background relative to the overall background intensity. In general, a minimum contrast value of 0.02 (2 percent) is needed by the human eye to distinguish differences between the image and its background. WebJul 4, 2024 · # calculate result: loss of global contrast: loss_global_contrast = C_global_T-C_global_L: return loss_global_contrast ## Calculate the local loss of contrast measure for one given pair of frames (tone mapped image together with corresponding HDR image). # @param image_hdr High Definition Range image (original image before tone mapping).
