pok
用于扑克的识别
主要原理是
先把左上角的截去一个角(涉及到智能判断切片大小)
之后通过区域查找和HSV模型
辨别出颜色
和找出相应的区域
然后利用编码形式
识别数字和花式(The main principle for the identification of poker is to first truncate the top left corner (relating to intelligence judgments slice size) after the HSV model through regional search and identify colors and find the appropriate form of identification coding region and then use digital and fancy)

Kelly的Solving Nonlinear Equations with Newton’s Method(This small book on Newton’s method is a user-oriented guide to algorithms and implementation.
Its purpose is to show, via algorithms in pseudo-code, in MATLAB, and
with several examples, how one can choose an appropriate Newton-type method for a given
problem and write an ef£ cient solver or apply one written by others.)
