Abstract: A method and apparatus for false contour detection and removal for video coding are disclosed. The method includes performing false contour detection by detecting a map of false contour candidate pixels from input image data through sequential evolution of a step of acquiring false contour candidate pixels based on each of a plurality of features of a human visual system in a manner that decreases the number of pixels to be detected in each sequential step, and performing false contour removal by removing a false contour in the input image data according to the map of false contour candidate pixels.
