Description: 实现9/7小波正反变换
注1： 采用标准正交方法，对行列采用不同矩阵（和matlab里不同）
注2： 为了保证正交，所有边界处理，全部采用循环处理
注3： 正交性验证，将单位阵带入函数，输出仍是单位阵（matlab不具有此性质）
注4： 此程序是矩阵实现，所以图像水平分量和垂直分量估计被交换位置
注5： 此程序实现的是类小波（wavelet-like）变换，是介于小波包变换与小波变换之间的变换
注6： 此程序每层变换相对原图像矩阵，产生的矩阵都是正交阵，这和小波包一致
注7： 但小波变换每层产生的矩阵，是相对每个待分解子块的正交矩阵，而不是原图像的正交矩阵
注8： 且小波变换产生的正交矩阵维数，随分解层数2分减少
注9: 提升系数可以在MATLAB7.0以上版本，用liftwave( 9.7 )获取，这里直接给出，考虑兼容性
注10：由于MATLAB数组下标从1开始，所以注意奇偶序列的变化
注11：d为对偶上升，即预测；p为原上升，即更新-Note 1: The standard orthogonal method, the ranks of the different matrices (and matlab where different)
Note 2: In order to ensure orthogonality, all boundary treatment, all with recycling
Note 3: Orthogonal validation, the identity matrix into the function, the output is still the unit matrix (matlab does not have this property)
Note 4: This program is a matrix to achieve, so the image horizontal and vertical components is estimated to be swapped
Note 5: This class implements the wavelet (wavelet-like) transformation, is between the wavelet packet transform and wavelet transform between
Note 6: This procedure transforms each image relative to the original matrix, the resulting matrix are orthogonal matrix, consistent with this and wavelet packet
Note 7: But each generation wavelet transform matrix, is to be broken down for each sub-block relative to the orthogonal matrix, rather than the original image of the orthogonal matrix
Note 8: Wavelet transf Platform: |

Starting from a new angle, through freely chosen frequency slice function, the introduction of a new scale parameter, the wavelet transform in the frequency domain, the transformation can portray the relative energy relations between the components of the signal. In addition, the frequency slice wavelet transform frequency is the observation of the time-frequency window center frequency without scale translation. Platform: |

Description: The fusion of images is the process of combining two or more images into a single image retaining important features from each of the images. A scheme for fusion of multi-resolution 2D gray level images based on wavelet transform is presented in this paper. If the images are not already registered, a point-based registration, using affine transformation is performed prior to fusion. The images to be fused are first decomposed into sub images with different frequency and then information fusion is performed using these images under the proposed gradient and relative smoothness criterion. Finally these sub images are reconstructed into the result image with plentiful information. A quantitative measure of the degree of fusion is estimated by cross-correlation coefficient and comparison with some of the existing wavelet transform based image fusion techniques is carried out.
