说明：  应用music算法和esprit算法在进行谱估计中的matlab源程序 (Music and esprit algorithm application in spectral estimation algorithm in the matlab source code)

This program is for reducing the noise in ultrasonic images by using redundant wavelet transform with bilateral filtration approach.

关于傅里叶变换和小波分析的基础知识内容。并附带基于Matlab案例进行说明。(Basic konwledge for Fourier transform and wavelet analysis with examples written in matlab )

Function reconstructs an estimate of a surface from its surface normals by correlating the surface normals with that those of a bank of shapelet basis functions. The correlation results are summed to produce the reconstruction. The sumation of shapelet basis functions results in an implicit integration of the surface while enforcing surface continuity. Note that the reconstruction is only valid up to a scale factor (which can be corrected for). However the reconstruction process is very robust to noise and to missing data values. Reconstructions (up to positive/negative shape ambiguity) are possible where there is an ambiguity of pi in tilt values. Low quality reconstructions are also possible with just slant, or just tilt data alone. However, if you have full gradient information you are better off with the Frankot Chellappa algorithm below.
