摘要： A method for frame memory compression divides each of a plurality of image frames in a frame memory into a plurality of blocks and quantizes a plurality of pixel values inside each block according to a predefined parameter, thereby generating a quantized block and a plurality of removed bits from the binary representation of the plurality of pixel values. A predictor is used to produce a residual block for the quantized block. A variable length encoder takes the residual block as an input and produces a coded bitstream. A packing unit is used to take the coded bitstream and the number of removed bits generated by the quantizer as inputs, so as to produce an entire codeword sequence of the block that meets a target bit rate by using a structure called group of blocks (GOB) to flexibly share available spaces of the blocks in the same GOB.

摘要： A system for image processing is provided. The system includes a region of interest (ROI) module receiving video from a camera and detects a ROI(s) in a first image. A lookup table generates a value responsive to block type for a first vanishing point (VP). A labeling module identifies a point “p” most close to the first VP, a point “q” most remote to the first VP and a length “h” between “p” and “q” in each ROI(s), and generates information on p, q and h. Another lookup table generates information on p′, q′ and h′, wherein p′ is a point most close to a second VP, q′ is a point most remote to the second VP and h′ is a length between p′ and q′ in ROI(s) in the second image. A transforming module transforms ROI(s) in the first image into an ROI in the second image.

摘要： Methods for fast mode decision of variable size block coding referring to spatial and temporal correlations between a current encoding motion block and at least one reference motion block to decide a best mode for encoding the current encoding motion block. The at least one reference motion block includes at least one neighboring motion block of the current motion block and/or a previous motion block that is located in a previous image frame at a position corresponding to that of the current encoding motion block in a current image frame. At least one block size mode is obtained from the at least one reference motion block. The methods further check the reliability of the at least one block size mode before using the at least one block size to encode the current motion block.
