说明:自己实现的canny边缘检测算子,包括高斯滤波,非极大值抑制,双阈值处理,边缘细化等步骤。-Own implementation of canny edge detection operator, including the Gaussian filtering, non-maxima suppre...
说明:先对已有心电信号进行读取,再人为加入一定的白噪声,然后运用小波阈值去噪法对加有白噪声的心电信号进行去噪,并给出原始,加有白噪声及去噪后的图像,另外还计算出了信噪比及均方根误差。
说明:用matlab实现setar预测模型的关键步骤:确定分段数d,分段区间门限值-the key steps to modeling SETAR prediction models with matlab is to determine the number of sub-paragraph d, su...
说明:该程序实现了基于小波模极大值,阈值去噪算法,并比较了各种方法的去噪效果。-The program achieved a de-noising based on wavelet modulus maxima algorithm, and effectively removes the signal i...
说明:小波去噪算法,改进阈值法去噪 Wavelet denoising algorithm, the improved de-noising threshold method
说明:取一个最优阈值把原图像分为前景色与背景色,两部分的类间方差越大,说明两部分差别越大,便能有效的分割图像。
