Description: A collection of functions is presented which includes 2nd generation wavelet decomposition and reconstruction tools for images as well as functions for the computation of moment invariants. The wavelet schemes rely on the lifting scheme of Sweldens. Rectangular grids are split into quincunx grids, also known as red-black ordering. The prediction filters include Neville filters as well as a few nonlinear ones fairly capable of preserving local maxima or minima. The decomposition and reconstruction functions are called in the style of the Matlab Wavelet Toolbox. Many small and a few elaborate examples have been included, ranging from the
computation of moment invariants to
multiresolution image fusion. Please
see Contents.m for an exhaustive list.

Description: 为了避免常规正交小波变换所引起的图像边缘失真，特别采用了双正交小波变换进行图像
的多分辨率分解。在融合处理时，为了获得更丰富的细节和更好的融合效果，对不同分解层、不
同方向上的高频分量以及同一分解层图像中的不同区域均采用不同的融合算子。实验结果表明，
该融合方法和融合规则是十分有效的，融合后图像的边缘和纹理细节都更加突出-In order to avoid the conventional orthogonal wavelet transform image edge distortion caused by the particular use of the biorthogonal wavelet transform for image multi-resolution decomposition. When the fusion process, in order to obtain richer detail and better integration of results for different decomposition layers, high frequency components in different directions within the same decomposition level of the image are different in different regions of the fusion operator. Experimental results show that the fusion and merging rule is very effective fusion of edge and texture detail can be more prominent Platform: |

Description: main executing reference usage: observeWaveletDecompositionBenchmark_N_levels.m
The objective is to illustrate wavelet decomposition, and to describe how operations may be done in the wavelet domain before the reconstruction. The demo decouples the wavelet operations (transform, operation in wavelet domain, and reconstruction) from the plotting.
A PSNR and MSE describes the possible distortion (however minimal) of the forward and inverse wavelet transform.
* Caveat: The image display may be subjected to the selected target image. The objective is to provide a simple framework for the understanding of working with wavelets. Platform: |

Description: Images require substantial storage and transmission resources, thus image compression is advantageous to reduce these requirements. The report covers some background of wavelet analysis, data compression and how wavelets have been and can be used for image compression. This project aims at implementing wavelet transform for image compression. The wavelet transform is implemented using Matlab.As the wavelets provide a unique relation between time and scale components of the signal, this property makes wavelets suitable for image compression and also the efficient decomposition of signals prior to compression.
