Filed:

Feb 20, 2001

Appl. No.:

09/937058

Inventors:

Chung-Tao Chu - San Jose CA, US
Wei Ding - Fremont CA, US

Assignee:

InterVideo, Inc. - Fremont CA

International Classification:

H04N 712

US Classification:

37524003

Abstract:

A system for improving the speed of the video encoding process by decreasing the number of cycles to perform the quantization. The disclosed system achieves the improvement through use of parallel processor such as one having a Single Instruction, Multiple Data (SIMD) architecture. Concurrent processing during one instruction cycle is accomplished, thereby leading overall to the use of fewer instruction cycles. In the preferred embodiment, an MMX instruction set is used for executing four quantization in parallel. The disclosed system also achieves a higher precision of the quantization during the encoding of video signals with the SIMD architecture by using a larger multiplier and larger shift factor.

International Classification:

G06G 7/58

US Classification:

703 11

Abstract:

The present invention relates to a method for developing algorithms that are capable of discriminating among different genotypes and subtypes of a virus of interest. The method includes aligning a set of viral nucleotide sequences having known genotypes and analyzing the aligned sequences to identify nucleotide positions at which the nucleotide is conserved within genotypes, but diversified across the different known genotypes. These positions, referred to herein as genotyping positions, are employed as predictive variables to compile a variable input table for analysis by a statistical classification algorithm. The variable input table also includes the nucleotide present at each genotyping position as a value and the genotype for each of the aligned sequences as a response variable. The algorithm analyzes the sequences of nucleotides at the genotyping positions across the aligned viral sequences, and uses the results of this analysis to specify parameters for each genotyping position that when combined across the genotyping positions will discriminate among the genotypes represented in the input sequences. The algorithm generated by this method is useful in a method of predicting the genotype of a viral isolate of interest, such as a virus present in a biological sample obtained from an individual.

International Classification:

G06F 1714

US Classification:

36472503

Abstract:

An array of DCT transform coefficients are converted to a two-dimensional array of spatial data in a video compression or decompression system. The array of DCT transform coefficients are divided into two groups. A regional IDCT algorithm is applied to all coefficients, both non-zero and zero, of the first group, while IDCT computation is applied to only non-zero coefficients of the second group. The results of the operations are then combined and/or mapped to form the output array of spatial data. In one specific implementation wherein an 8. times. 8 array of DCT coefficients are to be transformed, the first region is defined by the first quadrant of coefficients in the 8. times. 8 array. A regional IDCT algorithm is applied to both zero and non-zero coefficients in the first quadrant. The non-zero coefficients in the remaining three quadrants are calculated directly, and the results of the direct calculations are combined with the results of the regional IDCT algorithm applied to the first quadrant coefficients.

US Classification:

Abstract:

Motion vectors and associated errors which are determined in the course of encoding a video signal are used to determine whether respective macroblocks of two or more frames represent the same subject matter albeit displaced by motion represented by the frames. The motion vector errors are compared to a predetermined motion threshold. If a particular motion vector error is less than the motion threshold, the macroblocks corresponding to the motion vector error are determined to represent substantially identical subject matter and the corresponding motion vector represents displacement of the subject matter between the frames due to motion of the subject matter. Accordingly, differences between the macroblocks corresponding to the motion vector error are determined to be due primarily to noise and not to differences in the subject. Therefore, a relatively heavy temporal filter is applied between the macroblocks. Conversely, if a particular motion vector error is not less than the motion threshold, the macroblocks corresponding to the motion vector error are determined to represent different subject matter and only a spatial filter is applied to either macroblock.
