The present disclosure relates to systems and methods for image sharpening. The systems and methods may obtain a target image to be processed, the target image including one or more target pixels to be processed. For each of the one or more target pixels, the systems and methods may select one or more previous pixels and one or more subsequent pixels along a predetermined direction in the target image; determine a first gray value based on the one or more previous pixels and a second gray value based on the one or more subsequent pixels; select a target gray value from the first gray value and the second gray value based on an initial gray value of the target pixel; and determine an adjusted gray value of the target pixel based on the initial gray value and the target gray value.
