图像边缘检测(Canny 算法)的Java实现 Canny边缘检测算法 step1:用高斯滤波器平滑图象； step2:用一阶偏导的有限差分来计算梯度的幅值和方向； step3:对梯度幅值进行非极大值抑制； step4:用双阈值算法检测和连接边缘 -Edge Detection (Canny algorithm) to the Java Canny edge detection algorithm ste p1 : Gaussian smoothing filte

用c code來寫的gaussian filter,C code to write using the gaussian filter

Use to filter image using gaussian filter

对音频进行加噪滤波，然后比较处理性能。加高斯白噪声，不同滤波器进行滤波比较。-Adding noise to the audio filter, and then compare the processing performance. Adding Gaussian white noise, filtering comparison of different filters.
