Loop-Filtering and Post-Filtering for Low Bit-Rates Moving Picture Coding
The decompressed images from highly compressed data have noticeable image degradations such as blocking artifacts, corner outliers, and ringing noise, because most image coding standards quantize the DCT coefficients of 8×8-pixel blocks independently. A loopfiltering algorithm and a post-filtering algorithm, which can reduce the quantization effects, are described, and the performances of both ...
متن کاملLoop "ltering and post-"ltering for low-bit-rates moving picture coding
When an image is highly compressed by using the current coding standards, the decompressed image has noticeable image degradations such as blocking artifacts near the block boundaries, corner outliers at cross points of blocks and ringing noise near image edges. These image degradations are caused by quantization process of the 8 8 DCT coe$cients. In order to restore the decompressed image, a l...
متن کاملPre and Post-Filtering for Low Bit-Rate Video Coding
We propose pre and post-lters for low bit rate video coding. The purpose of the former is to make the video sequence easier to encode, whereas the latter aims to remove coding artifacts. The proposed techniques are computation-ally eecient and lead to scalable architectures which 1) can handle varied types of video content and 2) can be adapted to the available bandwidth and computational resou...
متن کاملAdaptive coding of moving objects for very low bit rates
This paper describes an object-based video coding system with new ideas in both the motion analysis and source encoding procedures. The moving objects in a video are extracted by means of a joint motion estimation and segmentation algorithm based on the Markov random field (MRF) model. The two important features of the presented technique are the temporal linking of the objects, and the guidanc...
متن کاملJoint Kalman-Based Noise Filtering and Motion Compensated Video Coding for low Bit Rate Videoconferencing
The problem of noise ltering for video coding applications is considered in this paper. In 1], an advantageous technique to combine a motion compensated (MC) noise lter with the coding loop of an MC hybrid coding scheme was illustrated, and a rate{distortion (RD) optimization framework was proposed. Here, we describe an alternative structure for denoising image sequences to be coded, which is b...
