查询词典 knowledge base

A new scheme of target discrimination in SAR images, consisted of frames, models and algorithms, is proposed. Under such a scheme, a global frame, combining orderly the algorithm based on feature extraction and that based on knowledge, is then proposed. Moreover, in the method of target discrimination based on feature extraction, a "loose-coupling" model is given. The existing features are chosen and three new features about the contrast are given under the "loose-coupling". Meanwhile, an algorithm of feature selection based on Genetic Algorithm is also modified to solve the problem that the existing algorithm can not evaluate the goodness-of-features comprehensively. The weighted quadratic distance discriminator is designed to improve the performance of target discrimination. Finally, a method based on the knowledge of target groups to remove clutter false alarms is also given.

Thus to accomplish even the beginning of his task the Theist has to show, against Agnostics, that the knowledge of God attainable by rational inference -- however inadequate and imperfect it may be -- is as true and valid, as far as it goes, as any other piece of knowledge we possess; and against Pantheists that the God of reason is a supra-mundane personal God distinct both from matter and from the finite human mind -- that neither we ourselves nor the earth we tread upon enter into the constitution of His being.

因此，要完成，甚至一开始他的任务者必须证明，对不可知论者，即知识的上帝所达到的，合理的推论-不过不足和不完善的，它可以是-是真实和有效的，因为到目前为止，因为它有云：至於其他任何一块知识，我们拥有；反对pantheists认为上帝的原因，是一种跨柴米油盐个人独特的神都从此事，并从有限的人的头脑-这既不是我们自己，也不是我们地球胎面后，进入宪法他的福祉。
