Centralized-Sparse-Representation

说明：  算差分盒维数的matlab程序。 让窗口中的每个像素都对分数维作出贡献。首先,计算某一尺度窗口的平均灰度值 ,然后判断每一个像素的灰度 ,若大于灰度平均值 ,则累加其灰度值为 max ,若小于灰度平均值 ,则累加其灰度值为min ,用max 和min代替 在 Sarkar 和 Chaudhuri 算法中的最大值和最小值 ,再通过拟合求出分数维。 (Differential count box dimension matlab program. Let window on the fractal dimension of each pixel to contribute. First, the calculation of an average gray scale of the window, and then determine the gray scale of each pixel, if the intensity is greater than the average, the cumulative value of its gray max, if less than the average gray level, the accumulation of its gray value of min, max and min to use instead of the algorithm in Sarkar and Chaudhuri maximum and minimum, and then by fitting the calculated fractal dimension.)

适用于simulink初学者，文件格式是PDF的。(Apply to beginners simulink, file format is PDF' s.)

用训练数据优化DPCM方法，对一个余弦信号数据进行标量量化。(we take optimize the training data DPCM method for the cosine signal data scalar quantization to get a wonderfull understanding.)

在盲辨识系统中，非常关键的是如何获得最好的辨识效果，这里采用了多种方法，通过系统建模，并比较方法(In blind identification system is critical to identify how to get the best effect, this uses a variety of ways, through system modeling, and comparison)

MATLAB代码,利用语音信号的短时能量与短时过零率来达到自动检测语音的起止点。效果不错.(MATLAB code, the use of short-time speech signal energy and zero-crossing rate of short-term to achieve automatic detection of the beginning and ending point of speech. Good results.)

对音频信号分帧加窗,对每帧进行三阶小波变换,取其逼近系数平均值(一般为零).在此嵌入二值图像 并有对潜入水印信号进行盲检,恢复其嵌入水印(Sub-frame of the audio signal increases the Hamming window for each frame impletment third-order wavelet transform, whichever is close to the average coefficient (usually zero). according to this embedding binary image and resume its embedded watermark from the watermark signal by the Blind detection)

说明：  数字信号处理的一些MATLAB源程序，均已经通过编译、仿真，请放心下载使用。(digital signal processing some of MATLAB source, we have already passed compiler, simulation, Please be assured download for use.)
