At present, a hyperspectral image has a significant advantage in the aspect of application because of its high spectral resolution. However, owing to the limit of communication capacity, a hyperspectral image must be compressed. In this paper, we develop and propose a fractal lossy hyperspectral image compression method based on prediction. First, we exploit spatial correlation by applying predictive...
Video compression has become more and more important nowadays along with the increasing application of video sequences and rapidly growing resolution of them. H.264 is a widely applied video coding standard for academic and commercial purposes. And fractal theory is one of the most active branches in modern mathematics, which has shown a great potential in compression. In this paper, this study proposes...
The original data of one view video is huge and that of multi-view video is much more. So, data compression is important for multi-views, and data compression is a key technology for multi-views. In this paper, we explore an efficient fractal video codec with multi-views. From the experimental results with the proposed method and other state of the art methods, we can conclude that the proposed algorithm...
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...
This paper mainly introduces three typical transform domain methods for image coding. Design programs of image transform domain coding algorithms based on DFT, DCT and WHT. For different input images, the paper compares their performances of compression and decompression through different algorithms. By introducing principles and detailed derivations of different transformations, it shows how to realize...
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...
