随机游走类似布朗运动，就是随机的向各个方向走吧。 虽然代码没什么技术含量，不过产生的图像实在太漂亮了，所以还是贴上来吧。 产生的图像：(Similar to Brownian motion random walk, is random and go in all directions. Although the code is no technical content, but the resulting image is too beautiful, so it is still Tieshanglai it. graphics layer.)

Mammography is one of the available techniques for the early detection of masses or abnormalities which is related to breast cancer. Breast Cancer is the uncontrolled of cells in the breast region, which may affect the other parts of the body. The most common abnormalities that might indicate breast cancer are masses and calcifications. Masses appear in a mammogram as fine, granular clusters and also masses will not have sharp boundaries, so often difficult to identify in a raw mammogram. Digital Mammography is one of the best available technologies currently being used for the early detection of breast cancer. Computer Aided Detection System has to be developed for the detection of masses and calcifications in Digital Mammogram, which acts as a secondary tool for the radiologists for diagnosing the breast cancer. In this paper, we have proposed a secondary tool for the radiologists that help them in the segmentation and feature extraction process.
