Extracting edge information for some regions instead of compressing them considerably increases overall image compression. | 2011-10-27 |
20110262050 | Two-Layer Prediction Method for Multiple Predictor-Set Intra Coding - An apparatus comprising a processor configured to receive a current block of an image, determine an optimal prediction mode of a plurality of prediction modes for the current block, wherein the optimal prediction mode corresponds to either a standard predictor set or a non-standard predictor set, predict a predicted predictor set based on a first known predictor set and a second known predictor set, clear a first flag if the predicted predictor set matches the optimal predictor set; and set the first flag if the predicted predictor set does not match the optimal predictor set. | 2011-10-27 |
20110262051 | METHOD FOR THE ENCODING BY SEGMENTATION OF A PICTURE - A method for encoding an image, the encoding being a mixed encoding with the possibility of using a first lossless compression type, and a second lossy compression type, the method including: dividing the image into a plurality of elementary blocks; determining which elementary blocks have a high level of detail; allocating the first type of compression to each elementary block that has a high level of detail; allocating the second compression type to each elementary block that does not have a high level of detail; applying the first type of compression to each elementary block to which the first compression type has been allocated; applying the first compression type to each elementary block directly surrounded by two elementary blocks to which the first compression type has been allocated. | 2011-10-27 |
20110262052 | IMAGE CODING APPARATUS, CONTROL METHOD THEREOF, AND STORAGE MEDIUM - Even in a case where there are a plurality of syntax elements, the invention reduces influence of the number of syntax elements and realizes high-speed encoding. An apparatus comprises N number of codes generation units arranged in parallel, which are configured to generate codes, including one or more codes, based on a transform coefficient; N number of first code concatenation units arranged in parallel, each of which is configured to concatenate the codes, respectively generated by the N number of codes generation units, for generating a code stream; N number of storage units arranged in parallel, each of which is configured to store the N number of code streams inputted from the N number of first code concatenation units; and a second code concatenation unit configured to read each of the code streams, which are stored in the N number of storage units, and concatenate the read code streams. | 2011-10-27 |
20110262053 | INFRARED RESOLUTION AND CONTRAST ENHANCEMENT WITH FUSION - The present disclosure relates to a method of improving an IR image comprising capturing a visual image and an IR image of an object, altering a resolution of at least one of said visual image and IR image, high pass filtering said visual image to generate a processed visual image, low pass filtering said IR image to generate a processed IR image, and combining information from said processed visual image and said processed IR image to generate a combined image. | 2011-10-27 |
