20130336388 | MOVING PICTURE CODING METHOD, MOVING PICTURE CODING APPARATUS, MOVING PICTURE DECODING METHOD, MOVING PICTURE DECODING APPARATUS, AND MOVING PICTURE CODING AND DECODING APPARATUS - Provided is a moving picture coding method for performing arithmetic coding on a quantization parameter to be used in quantizing a current block that is to be coded and is included in a current picture to be coded, the quantization parameter including a parameter indicating a sign and a parameter indicating an absolute value, the method including: binarizing the parameter indicating the absolute value without requiring information on a maximum value of the absolute value; binarizing the parameter indicating the sign without requiring information on a maximum value of the sign; and performing bypass arithmetic coding, using a fixed probability, sequentially on (i) a latter half of the binarized parameter indicating the absolute value and (ii) the binarized parameter indicating the sign. | 2013-12-19 |
20130336389 | SIGNAL ADAPTIVE FILTERING METHOD, SIGNAL ADAPTIVE FILTER AND COMPUTER READABLE MEDIUM FOR STORING PROGRAM THEREFOR - A signal adaptive filtering method for reducing blocking effect and ringing noise, a signal adaptive filter, and a computer readable medium. The signal adaptive filtering method capable of reducing blocking effect and ringing noise of image data when a frame is composed of blocks of a predetermined size includes the steps of: (a) generating blocking information for reducing the blocking effect and ringing information for reducing the ringing noise, from coefficients of predetermined pixels of the upper and left boundary regions of the data block when a frame obtained by deconstructing a bitstream image data for inverse quantization is an intraframe; and (b) adaptively filtering the image data passed through inverse quantization and inverse discrete cosine transform according to the generated blocking information and ringing information. Therefore, the blocking effect and ringing noise can be eliminated from the image restored from the block-based image, thereby enhancing the image restored from compression. | 2013-12-19 |
