摘要: A method and system for improving the quality of a video image (100) segmented into a plurality of blocks (110, 115, 120) of known size is disclosed. The method comprises the steps of associating a value to each of said blocks and altering said associated value corresponding to a selected one of said blocks when each of said associated values of blocks adjacent to said selected block is different than said selected block associated value. The block value is a first value when said block probability function is greater than a threshold value, otherwise it a set as a second value.

摘要: Pixels in a video image may be segmented based upon selected criteria, such as a common color, texture, shape, amplitude range or temporal variation. Color values for these pixels may be used to calculate a color probability function which indicates the probability that the color value of the pixel will lie within a designated range of values. The pixels are also used to calculate a texture probability function that indicates whether the pixel represents a designated texture. Pixels that are assigned to a given segment may then be further processed to improve the quality of an image. In this manner, pixels that identify grass, sky, human skin, etc. may be identified and processed in order to achieve a more pleasing appearance.

摘要: A system and method to render 3D images from a 2D source are described. An embodiment of a method to render 3D images from a 2D source comprises the steps of providing a graphics rendering device to estimate depth of a 2D image; providing video or graphics textures and depth-maps to describe an object in a 3D scene; creating, in one embodiment, a single view angle and in another preferred embodiment at least two view angles of the 3D scene to represent an intraocular distance using the graphics rendering device; and presenting both of the at least two view angles on a display using the graphics rendering device and especially the commonly available 3D imaging technology of the graphics rendering device.

摘要: A de-interlacing device and method are provided that may be used in a memory based video processor. The de-interlacer mixes the output of a temporal de-interlacer and a spatial de-interlacer. Two separate error values are used; one for the temporal de-interlacer and another for the spatial de-interlacer. The de-interlacing device calculates from the two error values, using a non-linear mapping, a mix factor used to mix between the outputs of the spatial and temporal de-interlacers.

摘要: In a video processing system where motion vectors are estimated for a subset of the blocks of data forming a video frame, and motion vectors are interpolated for the remainder of the blocks of the frame, a method includes determining, for at least at least one block of the current frame for which a motion vector is not estimated (204), whether a block to the left or right has an estimated zero motion vector (206), determining whether the at least one block had an estimated zero motion vector in a previous frame (206), and if both determinations are affirmative (208), providing a predetermined motion vector for the at least one block. The predetermined motion vector may be a zero motion vector (208).
