It has been deduced that the search direction remains the same but that the step length decreases in optimizing the improved cost function with the conjugate gradient algorithm from the gradient of the cost function that the FIR filter apporaches the contrary point spread function more, and that the estimated image is closer to the original one.

从代价函数的梯度入手推导出共轭梯度算法，其搜索方向保持不变而搜索步长变小，使滤波系数更加逼近于点扩展函数逆算子，从而使估计图像与原始图像更加接近。

It modified some terms of the initial formula, which made the snake model not only precisely extract the edge of the protruding object in images but also approach to the concave part of the edge. It introduced exterior sanction energy, which could adaptively change its value to enlarge suction, so that control points could quickly constringe to the real contour without relying on the initial contour. Combined with pattern matching, this new method could increase the precision of transferring the result of edge extraction from one slice to another.

通过调整原始公式的一些参数使得该模型不但能精确地提取图像中的凸形物体的边缘，而且能够接近边缘的凹陷处；引入自适应改变大小的外部约束能量来增大外能的吸引范围，使控制点能够不依赖于初始轮廓而快速地收敛到目标的真实轮廓；结合匹配技术，提高边缘提取结果层间传递的精度。

The test results indicate that Lambert cosine radiation characteristic of the new method has a distinct improvement, and the incidence normalized curve approaches to the standard cosine curve in the 0° and 45°.

测试结果表明，新工艺的朗伯余弦辐射特性得到明显改善，在0°与45°入射时，归一化曲线接近标准余弦曲线；300 nm处半球反射率均匀度从0.77提高到0.98；200~400 nm处半球反射率平均提高33%；将其应用于紫外－真空紫外遥感仪器上进行了角度响应测试，漫反射特性明显优于美国2002年发射的同类仪器SBUV/2。
