基于Hessian矩阵对输入的心血管图像进行增强和分割(The input cardiovascular images are enhanced and segmented based on the Hessian matrix)

说明：  实现 %1、利用RGB模型识别天空区域；2、利用边缘识别检测天空边缘分割线；3、利用预测边缘点和实际边缘点的周围区域的均值滤波与本边缘点下方的像素之间的差异大小来修正天空边缘分割线 %4、将sky_seg+depthmap_v2中多余的带注释的地方删掉了 %！！！记得在295行，一定要改动是用I6还是I7，如果用sky_initia(f = edge(double(BW),'canny',thresh,sigma);)

说明：  基于卡尔曼滤波的camshift算法，实现目标跟踪(CAMSHIFT algorithm based on Kalman filter for target tracking)
