Wavelet transforms and edge detectors on digital images

摘要: The paper investigates the problem of locating edges on digital images. process is completed through various mathematical transforms. are found by implementing algorithms for convolutions that adapted to locate and highlights technique using wavelet We especially addressing edge detection, because it has far reaching applications all fields within medicine. A patient can be diagnosed as having an aneurysm studying angiogram. An angiogram visual view blood vessels whereby highlighted implementation detectors. This transforms other convolution techniques.
