1. An image processor comprising:
a pre-processor configured to perform spatial filtering on an input image signal and output a line image signal corresponding to a single scan line;
a segmentation processor configured to classify a class of the line image signal and 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; and
a correction processor configured to correct the segmentation signal based on the line image signal, wherein the correction processor detects a class boundary of the segmentation signal, wherein the class boundary indicates a first point among the horizontal positions of the line image signal, detects an edge within an edge region of the input image signal, wherein the edge comprises a second point among the horizontal positions of the line image signal, and corrects the segmentation signal based on the detected edge.
