Description: 针对TCP (Transmission Control Protocol) 协议在高速卫星因特网中传输吞吐量低的问题, 提出了一种改
进TCP快速恢复的算法。该算法根据卫星信道由传输错误造成的分组丢失概率远大于由拥塞造成的分组丢失
概率的特点, 通过加快窗口的增长速度, 避免过早地进入拥塞避免阶段, 达到了提高TCP吞吐量的目的。通
过NS2软件模拟仿真了高速卫星因特网环境, 并对各个TCP版本和改进算法的仿真结果进行了比较和分析。
仿真结果表明, 改进算法的吞吐量比TCP2SACK提高了约10 , 比TCP2Reno提高了约30 。-A new algorithm is p roposed to imp rove the throughput of high speed satellite&internet network. In
satellite channels, most of lost package is due to transmission error instead of congestion. We can make some im2
p rovement on TCP (Transmission Control Protocol) fast recovery algorithm. Bymaking the window increase fas2
ter and not enter congestion avoidance too early. We imp rove the throughput of TCP. We use NS2 to simulate the
environment of satellite and internet network, and the results are compared. In simulation, about 10 through2
put in our algorithm is imp roved than TCP2SACK, and that is about 30 imp roved than TCP2Reno.
Key words: high speed satellite and internet network satellite channel transmission control p rotocol ( TCP)

Description: 这里使用了双线性插值来处理极坐标转换到直角坐标下时，点不对称的问题，不过最后生成的图有一点问题，本来应该是一圈一圈的圆环，但是转化后的只有部分圆环了
rMin = 0.1 rMax =0.9
im2 = imread( ivus.bmp )
figure(4) imshow(im2)
imR2 = PolarToIm(im2, rMin, rMax, 300, 300)
figure(5) imshow(imR2, [0 255])
然后直接调用附件的function就可以了。
可否请各位大大修正一下这个程序，或者更简便的算法！~ 谢谢了！-There is a reference function code, use bilinear interpolation to convert polar coordinates to Cartesian coordinates, point asymmetric, but the final plans generated it was supposed to be a circle ring, but the conversion is only partially annular RMIN = 0.1 RMAX = 0.9 IM2 = imread (the ivus.bmp ) Figure (4) the imshow (IM2) IMR2 = PolarToIm (IM2, Rmin, RMAX, 300, 300) figure (5) the imshow (imR2 [0 255]) then directly call the annex to function on it. Can I please greatly amend this program, or more simple algorithm! ~ Thank you!

Description: 传统Snake 模型存在的缺点是, 其初始轮廓必须靠近图像中感兴趣目标的真实边缘,否则会得到错误结
果,且由于Snake 模型的非凸性,结果不能进入感兴趣目标的深凹部分,很容易陷入局部极小点. 由此该文提出一
种基于力场分析的主动轮廓模型,详细分析了基于欧氏距离变换的距离势能力场分布,归纳出感兴趣目标上真轮
廓点与假轮廓点的判别标准. 建立了由曲线能量到最终结果的有效方法,避免了Snake 陷入局部极小点. 实验结果
表明,该模型具有较大的捕获区域,能够进入感兴趣目标的深凹部分,准确提取感兴趣目标的轮廓. 与GVFSnake
模型相比, 该模型具有很小的计算量.-The t raditional snake initial contour should be close to the t rue boundary of interested ob2
ject in an image , or else it would converge to the wrong result . Next , active contours have difficulties
progressing into boundary concavities. Moreover , the t raditional snake and it s almost kinds of im2
proved methods are easy to get into local minimum because snake models are non2convex. An active
contour model based on force field analysis , namely FFASnake model , is presented in this paper.
Based on analyzing force dist ribution rules of distance potential force field , a standard is int roduced
here to distinguish the false one f rom contour point s.
