用cany方法对lenna图像进行边缘检测，进行了具体的编程，没有调用matlab的集成的函数-By cany method lenna image edge detection, carried out specific programming, without calling matlab function integration

hough变换，matlab编程。Hough变换是一种使用表决原理的参数估计技术。其原理是利用图像空间和Hough参数空间的点－线对偶性，把图像空间中的检测问题转换到参数空间。通过在参数空间里进行简单的累加统计，然后在Hough参数空间寻找累加器峰值的方法检测直线。-hough transform, matlab programming. Hough transform is a vote on the principle of using a parameter estimation tech

Medical image processing is the most challenging and emerging field now a days. Processing of MRI images is one of the part of this field. This paper describes the proposed strategy to detect & extraction of brain tumour patient’s MRI scan im
