1. An interactive image marking method, comprising the steps of:
displaying a target image and at least one marked region in the target image;
receiving an interactive signal, wherein the interactive signal corresponds to a first pixel of the target image;
calculating a first correlation between the first pixel of the target image and other pixels of the target image;
determining a correlation range in the target image according to the first correlation;
editing the at least one marked region according to the correlation range; and
displaying the at least one marked region edited;
wherein the interactive signal is an expansion signal, and the interactive image marking method further comprises:
calculating a distance relation between the first pixel and the at least one marked region; and
selecting a target region from the at least one marked region according to the distance relation, wherein the step of editing the at least one marked region according to the correlation range comprises marking the correlation range to expand the target region.
