Описание:
Fractal image compression is a lossy technique with high compression ratios, good quality, and fast decoding. However, the computational complexity and long coding time makes it unpractical. This book introduces possible solutions for these problems. In the book, A full quadtree and a full binary-tree searchless fractal algorithms introduced in chapter 1 and 2. The full quadtree algorithm introduced in chapter 3 has a simpler data structure allowing a hardware implementation. The two-level quadtree algorithm introduced in chapter 4 is an improved version of chapter 3. Chapter 5 gives a two-level fractal FPGA hardware architecture design corresponding to chapter 3. Chapter 6improves the result of chapter 5 by employing 4 quadtree levels. The most important findings of this book are: 1. The algorithms fix the location of domain block. It reduces the complexity of the fractal encoding. 2. The algorithms can encode smaller range blocks, even single pixels. This is unique among current...Похожие книги
