Methods Using broadband convex array probe, to scan suspicious area of the ureter, changes of two-dimensional gray scale, with color and power Doppler.
方法使用宽频凸阵探头、对输尿管可疑部位、变化进行二维灰阶、彩色和能量多普勒扫描。
Based on the characteristic of each part, different gray scale transforms are designed to carry out image linear enhancement to get the best visual effect for the interested area.
按照每一部分的特点，设计不同的灰度变换，对图像进行分段线性增强，得到感兴趣目标区的最佳视觉效果。
Then, vehicle validation process is accomplished by local entropy and local gray scale symmetry estimate. Finally, the validated ROI area is filtered to obtain the ultimate detection results.
最后，通过基于局部信息熵和局部灰度对称性测度的假设验证对ROI区域进行验证并对验证后的车辆区域进行滤波，得到最终检测结果。
