对含噪声的图像进行识别和估计，通过小波分解，在频域中完成对图像的识别，判断是椒盐噪声还是高斯噪声，并对参数的值进行估计。-Identify and estimate noisy images, through the wavelet decomposition in the frequency domain to complete the image recognition to determine the salt and pepper noise or Gaussian noise, and

摘要文中算法首先在曲线尺度空间中通过高斯平滑以消除噪声；然后再基于自适应弯曲度计算和角点筛选准 则确定角点. 该算法不需要预先输入参数，具有较好的抗干扰性，实现简单有效. 关键词高斯平滑；尺度空间；自适应；角点检测-Abstract In image processing，corner point means the dominant point of maximum curvature aiong the bounding edge of pianar object. A meth

we present an improved fuzzy C-means (FCM) algorithm for image segmentation by introducing a tradeoff weighted fuzzy factor and a kernel metric. The tradeoff weighted fuzzy factor depends on the space distance of all neighboring pixels and th
