In this paper, we explore the fractal video sequences coding in the context of region-based functionality. Since the main drawback of fractal coding is the high computational complexity, some schemes are proposed to speed up the encoding process. 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 conventional...
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...
This paper presents an improved fast fractional pel motion estimation algorithm for H.264. First, to skip inefficient fractional pel search, smooth macro-block prediction algorithm is proposed. Then, to further reduce the computation load of H.264 fractional pel motion estimation, an extended diamond pattern search algorithm based on predicted motion vector is proposed. The simulation result shows...
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...
