摘要： A method for block matching includes performing a first search for a matching block in a frame using a search pattern centered at a first center point and determining a best point that produces a close match. If the best point does not produce a match satisfying a criterion, the method further includes storing the first center point in an array, setting the best point as a second center point, and performing a second search using the search pattern centered at the second center point. Performing the second search includes (1) at least approximating distances between (a) points in the search pattern centered at the second center point and (b) center points stored in the array; (2) excluding any point that has at least one distance less than a threshold; and (3) performing the second search for remaining points in the search pattern centered at the second center point.

摘要： Disclosed is a method for preparing L-α-Glycerylphosphorylcholine with high yields and purity. The method uses phospholipase A1-based enzymatic hydrolysis, ion-exchange resin purification and silica gel column chromatography to prepare L-α-glycerylphosphorylcholin with purity up to 99.8% and a final yield up to 78.4%. The method disclosed is simple, cost-effective, environmentally friendly, and adaptable to industrial applications.

摘要： A method for real-time video encoding includes buffering frames in an encoder input buffer, retrieving the frames from the encoder input buffer, encoding the retrieved frames into a bit stream, monitoring the encoder input buffer for buffer overflow, and, if the encoder input buffer is about to overflow, encoding one of the retrieved frames as a pseudo-frame that completely references one reference frame of the one retrieved frame. Encoding one of the retrieved frames as a pseudo-frame bypasses a majority of the encoding procedures to improve the overall encoding speed. The method further includes monitoring a hypothetical decoder input buffer that models an actual decoder input buffer in a video decoder, encoding one of the retrieved frames with a pseudo-frame if the hypothetical decoder input buffer is about to underflow, and adding stuffing bits to the bit stream if the hypothetical decoder input buffer is about to overflow.
