Fractal image coding method is a novel compression method, in which the local self-similarity of the image is used to eliminate cross-scale redundancy existing in image data. It receives wide academic attention with its innovative idea, high compression ratio, high decoding speed, independent resolution etc. however, for the encoding time and quality of decoding needs to be improved, there have been...
Fractal coding is a recent and effective compression technique based on self-similarity of images. However, its encoding time is very high. In addition, when 2-D fractal coding is applied directly to field-sequential stereo video sequences, the high vertical-frequencies of stereo image pairs are suppressed. This makes the depth perception defective. In this paper, a survey of fractal coding development,...
Based on the classical fractal video compression method, an improved monocular fractal compression method is proposed which includes using more effective macroblock partition scheme instead of classical quadtree partition scheme; using improved fast motion estimation to increase the calculation speed; using homo-I-frame like in H.264, etc. The monocular codec uses the motion compensated prediction...
We proposed a novel fractal video coding method using fast block-matching motion estimation technology to overcome the drawback of the time-consuming character in the fractal coding. As fractal encoding essentially spends most time on the search for the best-matching block in a large domain pool, this paper firstly ameliorates the traditional CPM/NCIM method and applies a new hexagon block-matching...
Based on the classical fractal video coding scheme, a novel hybrid video coding scheme joint fractal and object-based function is proposed. A new technique of object-based fractal video coding in which each object can be encoded and decoded independently results in increasing compression ratio and speed and reducing bit rate and bandwidth is used. The proposed techniques include: using more effective...
In the paper, a novel fractal monocular video codec is proposed which includes: using new macroblock partition scheme instead of classical quadtree partition scheme; reducing the block searching strategy and range, thus increasing the calculation speed greatly; using homo-I-frame like in H.264; reducing repeating calculation. The fractal monocular video codec uses the MCP structure. And the fractal...
