An edge compensated feature detector includes a local difference unit receiving an incoming video signal and calculating a local difference value according to a component difference in a local area of a video frame formed by the incoming video signal; an adjustment unit coupled to the local difference unit for mapping the local difference value onto an edge gain value; a feature extraction unit for extracting a particular feature of the incoming video signal; and a multiplier coupled to the adjustment unit and the feature extraction unit for multiplying feature data corresponding to the output of the feature extraction unit with the edge gain value to thereby generate an edge compensated feature component.
