ENVI二次开发示例――波段波谱运算的IDL源代码

Introduction Icasso is based on running FastICA several times (resampling). Icasso pools all the estimates together and forms clusters bottom-up among them. The basic idea is that a tight cluster of estimates is considered to be a candidate for including a "good" estimate. A centroid of such cluster is considered a more reliable estimates than any estimate from an arbitrary run. (Instead of an average as a centroid, Icasso visualizes and returns a centrotype from each cluster. This is the one of the original estimates that is most similar to other estimates in the same cluster. You can compute the average by using Icasso functions.)

目标跟踪，本文围绕人运动的视觉分析中的重要课题――基于模型的行人跟踪――展开研究,它不仅涉及底层视觉的许多问题,还是高层视觉处理的基础。基于模型的跟踪是解决行人跟踪问题的一般性框架。-A Method of Passing People Tracking and Counting Based on Real- Time Image- Sequence

传统的单粒子重建方法使用傅立叶或delta 函数基础来表示粒子密度图。我们提出了一个更灵活的算法，可以根据数据适应性地选择基础。由于基础适合数据，跟使用固定基础重建相比，分辨率和讯噪比(SNR) 都得到提高。而且，该算法自动遮盖粒子，使得粒子从背景中分离出来，无需在精制循环中使用专门滤波器或者蒙层。该算法是基于贝叶斯定理最大后验框架中表示，使用有效优化算法获得最大化。评估使用模拟和实际的低温电子显微镜数据，显示分辨率和 SNR 改进以及从背景中有效遮挡粒子。
