边缘提取技术边缘是图像对视觉的最主要特征，因此在计算机视觉技术中提出了多种检测边缘的算法。由于各种原因，图像常常受到随机噪声的干扰，经典的边缘检测的结果常常是将噪声误检为边缘点，而真正的边缘由于噪声干扰却可能被漏检。因而对于被噪声污染的图像来说，一种好的边缘检测方法应具有良好的噪声抑制能力，同时又有完备的边缘保持特性。(After analysing the soft threshold funetion,the smoothness threshold function is proposed by modifying the soft threshold function.because this function keeps smooth in the entire value range,some important details in the process of image denoising can be held. Firstly we detect the edge of the noising image. )
