Claim:
1. A computer-implemented method for adjusting pixel saturation, the method comprising: accessing, by one or more computing devices, a target distribution function associated with at least one target aerial image, the target distribution function defining a target probability for a pixel saturation of each pixel within the at least one target aerial image; accessing, by the one or more computing devices, an input distribution function associated with at least one input aerial image, the input distribution function defining an input probability for an initial saturation value of each pixel within the at least one input aerial image, the at least one input aerial image depicting an aerial view of an entirely different geographic area than the at least one target aerial image such that content contained within the at least one input aerial image differs from content contained within the at least one target aerial image, the input distribution function differing from the target distribution function such that a pixel saturation distribution for the at least one input aerial image differs from a pixel saturation distribution for the at least one target aerial image; determining, by the one or more computing devices, the input probability associated with the initial saturation value of each pixel within the at least one input aerial image based on the input distribution function; determining, by the one or more computing devices, a target saturation value based on the target distribution function at which the target probability is equal to the input probability for the corresponding initial saturation value, the target saturation value differing from the corresponding initial saturation value; and adjusting, by the one or more computing devices, the initial saturation value of each pixel within the at least one input aerial image to the corresponding target saturation value.
