Abstract: An adaptive de-interlacer can convert an interlaced video signal into a progressive video signal, and comprises a motion detector, an intra-field interpolator, an inter-field interpolator, a motion aliasing artifact detector and a blending unit. The motion detector generates an alpha value for each interpolated pixel in a current field of the interlaced video signal based on successive fields of the interlaced video signal. The intra-field interpolator outputs an intra-field interpolated pixel based on the current field, and the inter-field interpolator also outputs an inter-field interpolated pixel based on the successive fields. Afterward, the motion aliasing artifact detector detects whether the interpolated pixel is located in a motion aliasing area.

Abstract: This invention provides a method and computer-readable medium for detecting flesh-tone regions in pictures, images, and videos. First, a flesh-tone axis is defined in a color space coordinate system, the flesh-tone axis passing through both the center of a flesh-tone region and the origin of the color space coordinate system. A perpendicular point, is then calculated on the flesh-tone axis as being the point having the shortest distance to an input pixel. A first distance and a second distance are then calculated based on the coordinates of the input pixel, the perpendicular point and the center of the flesh-tone region. The determination as to whether the input pixel is in the flesh-tone region can be made based on the first distance and second distance.
