A Full-Fuzzy Rate Controller for Variable Bit Rate Video
In this paper, we propose a new full-fuzzy video ratecontrol algorithm (RCA) for variable bit rate (VBR) videoapplications. The proposed RCA provides high qualitycompressed video with a low degree computational complexity.By controlling the quantization parameter (QP) on a picturebasis, it produces VBR video bit streams. The proposed RCAhas been implemented on the JM H.264/AVC video codec andth...

متن کاملAn Enhanced Hybrid Content-Based Video Coding Scheme for Low Bit-Rate Applications
This paper presents a hybrid content-based video coding scheme that encodes arbitrary shaped objects instead of blocks of images. The scheme achieves efficient compression for low bit-rate applications by separating moving objects from stationary background and transmitting the shape, motion and residuals for each segmented object. Furthermore, a new content-based object segmentation algorithm ...
متن کاملContent Based Very Low Bit Rate Video Coding Using Wavelet Transform
In this paper we present a new hybrid compression scheme for videoconferencing and videotelephony applications at very low bit rates (i.e., 32 kbits/s). In these applications, human face is the most important region within a frame and should be coded with high fidelity. To preserve perceptually important informat ion at low bit rates, such as face regions, skin-tone is used to detect and adapti...
متن کاملAdaptive motion-compensated video coding scheme towards content-based bit rate allocation
An adaptive motion-compensated video coding scheme, that is based on structural video component segmentation and coding complexity analysis, is proposed in this paper. The bits are allocated more efficiently among different frame types and variant video components. A novel scene cut detection algorithm is proposed for partitioning the input video sequences into a set of shots and each shot may ...
