该讲义《光学系统的设计与校正》为耶拿大学光学设计大师Herbert Gross编写，对于像差理论及校正方法有详细阐述，光学设计相关人员可参考。

一本很牛的有关纠错码的书，纸质书很贵，电子书下载居然要好多几分，我等穷人很不爽，好不容找了一个，免费提供，坐看那些奸商哭

简介：纠正诸如“ campagn”（活动）之类的拼写错误相对容易。 但是，如果您打算键入“三”，则常见的错误是键入“有”而不是“三”。 “有”和“三个”的拼写正确。 但是，如果我们比较短语“三天”和“有天”，则显然“三天”是正确的短语。 如何使您的拼写校正算法识别上述差异？ 在此程序中，我尝试使用上下文中的信息来解决此问题。 所需的Python软件包：re，collections，nltk，numpy，operator，csv，sys兼容性：该程序经过测试，可以使用Anaconda发行版在Python 3.6.5上运行 该程序需要几分钟才能运行给定的示例。 因此，请耐心等待。 如何运行：python3 main.py inputFileLocation For example, python3 main.py /Users/tg/Desktop/517/assignment2/i

This Application aim to detect the lines using Sobel or my custom Algorithm. In image processing, this app associated with Edge Detection and Fixed pattern Noise.

The first photon bias of photon detection results in distortion of the photon waveform, which seriously affects the accurate acquisition of target information. A rapid universal recursive correction method is proposed, which is suitable for multi-trigger and single-trigger modes of photon detection. The calculation time is 2 to 3 orders of magnitude faster than that of Xu

An infrared image detail enhancement method based on local adaptive gamma correction (LAGC) is proposed. The local adaptive gamma values are designed based on the Weber curve to enhance effectively the image details. Subsequently, the active grayscale range of the image processed by LAGC is further extended by using our proposed histogram statistical stretching. The experimental results show that the proposed algorithm could considerably increase the image details and improve the contrast of the

Space Technology Experiment and Climate Exploration (STECE) is a small satellite mission of China for space technology experiment and climate exploration. A new test star tracker and.one ASTRO 10 star tracker have been loaded on the STECE satellite to test the new star tracker’s.measurement performance. However, there is no autonomous precession–nutation correction function for the test star tracker, which causes an apparent periodic deflection in the inter-boresight.angle between the two star t
