说明：  学习和掌握简单条件下规则形体重力异常的正演计算方法和形态特征，加深对课堂理论内容的理解。 根据指定形状地质体，选择不同产状和密度参数，计算出重力异常及其导数的正确结果。绘制相应的剖面异常图，观察曲线形态。(Learn and master the forward calculation method and morphological characteristics of gravity anomaly of regular body under simple conditions, and deepen the understanding of classroom theoretical content. According to the specified shape geological body, different occurrence and density parameters are selected to calculate the correct results of gravity anomaly and its derivative. Draw the corresponding profile anomaly map and observe the curve shape.)

对两幅图像提取特征点，并计算基本矩阵，对两幅图像进行极线矫正，并画出校正后图像特征点的极线，效果非常好(The two images of the image feature points in the feature points are extracted, and the calculated fundamental matrix, correction of lines of the two images, and after the draw correction lines, very good results)

说明：  基于灰度矩的亚像素边缘检测，零件边缘提取(Subpixel edge contour extraction)

对灰度图像或RGB图像，进行基于边缘检测和区域生长的图像分割技术(On grayscale images or RGB images, for edge detection and region growing-based Segmentation)

将RGB彩色空间转换到HSI彩色空间，HSI彩色空间更接近人眼对彩色的认知。(The RGB color space conversion to the HSI color space, HSI color space is closer to the human eye color perception.)

this code is for the paper of image segmentation based on level set methods. in this paper improves Tony Chan s paper and improves the speed.
