Claim 13:
14. An operation method of a display device, the method comprising:
performing spatial filtering on an input image signal to output a line image signal corresponding to a single scan line;
classifying a class of the line image signal to output a segmentation signal representing the class, wherein the segmentation signal comprises a single valued function with a one-dimensional domain corresponding to horizontal positions of the line image signal;
detecting a class boundary of the segmentation signal, wherein the class boundary indicates a first point among the horizontal positions of the line image signal;
computing an edge region of the line image signal, wherein the edge region comprises a range of the horizontal positions of the line image signal including the first point;
detecting an edge within the edge region of the line image signal, wherein the edge comprises a second point among the horizontal positions of the line image signal; and
correcting the segmentation signal based on the detected edge.
