SPECTRAL_ANALYSIS M-file for spectral_analysis.fig SPECTRAL_ANALYSIS, by itself, creates a new SPECTRAL_ANALYSIS or raises the existing singleton*. H = SPECTRAL_ANALYSIS returns the handle to a new SPECTRAL_ANALYSIS or the handle to the existing singleton*. SPECTRAL_ANALYSIS( CALLBACK ,hObject,eventData,handles,...) calls the local function named CALLBACK in SPECTRAL_ANALYSIS.M with the given input arguments. SPECTRAL_ANALYSIS( Property , Value ,...) creates a new SPECTRAL_ANALYSIS or raises the existing singleton*. Starting from the left, property value pairs are applied to the GUI before spectral_analysis_OpeningFcn gets called. An unrecognized property name or invalid value makes property application stop. All inputs are passed to spectral_analysis_OpeningFcn via varargin.

Brodatz Album 库中任取10幅图像，每幅图分成四小块，得到40幅小图像，取其中一幅小图像，对大图中其余三幅小图进行检索(image retrieval)

数字水印图像的攻击测试 包括滤波、剪切、添加噪声、jepg压缩攻击等等(Attack test digital watermarking images, including filtering, cropping, adding noise, jepg compression attack, etc.)

This is the thwaites method for boundary layer over flat plate . This is an empirical method based on the observation that most laminar boundary layers obey the following relationship .it will help our calculate coefficient drag , velocity over flat plate.
