本书首次出版于1959年，其前身是诺贝尔奖得主马科斯?玻恩（Max Born）的Optik一书，目前的最新版本是1999年第七版。《光学原理》一书在国外被广泛称为“Born & Wolf”已经销售超过30万册。事实上，每一个科班出身学习光学的人都研读过这本书并深受其影响。近半个世纪以来，“Born & Wolf”一直是物理书架上必不可少的作品，并成为光学领域的奠基性教科书。
This book was first published in 1959, its predecessor is a Nobel Prize winner Marcos? Born (Max Born)' s Optik a book, the latest version of the current seventh edition in 1999. " Optics," a book in foreign countries is widely known as the " Born & Wolf" has sold more than 300,000. In fact, every curriculum, studying optical everyone had this book and studied deeply their impact. Nearly half a century, " Born & Wolf" has always been essential to the physical works on the shelves and become the cornerstone of the field of optics textbook. (2009-11-10, Others, 30698KB, 下载19次)
一种基于贝叶斯理论的目标验证方法。
提出了一种验证图像中候选目标的新方案. 综合目标的先验知识,将目标验证转化为给定候选目标的条
件下,图像特征观察集合的条件概率问题. 同时,提取图像的短线段特征,利用短线段特征的观察,给出了一种目标
验证方法排除复杂场景图像中虚假建筑物目标. 在自然图像集上进行的实验表明,所提出的方法能有效排除虚假
目标,满足处理自然图像的要求.
Based on Bayesian theory the goal of authentication methods. A candidate for the target image to verify the new program. Comprehensive prior knowledge of the target, the target to verify the candidate into a given target under the conditions of image feature observe the collection of conditional probability problems. At the same time, extract the image characteristics of short-paragraph the use of short-term observation of the characteristics above, given a goal of authentication method to exclude false images of complex scenes building goals. Set in the natural image experiments show that the proposed method can effectively rule out the possibility of false targets, to meet the deal with natural images requirements.
