There is provided a method of processing digital images, comprising: selecting a reference digital image according to a uniform distribution requirement of pixel intensity values, performing for each certain overlapping image that overlaps with at least one other image at a respective overlapping region: computing a value for each respective gamma parameter for each channel of the certain overlapping image to obtain a correlation between pixel intensity values, corrected with the respective gamma parameters, of each channel of each overlapping region of the certain overlapping image, and pixel intensity values, corrected with respective gamma parameters, computed for each of the at least one other image, for each channel of each respective overlapping region, and creating corrected images by applying the computed value of each respective gamma parameter to the overlapping and non-overlapping regions of each certain overlapping image of the plurality of overlapping images.
