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)

autocov computes the autocovariance between two column vectors X and Y with same length N using the Fast Fourier Transform algorithm from 0 to N-2. The resulting autocovariance column vector acv is given by the formula: acv(p,1) = 1/(N-p) * sum_{i=1}^{N}(X_{i} - X_bar) * (Y_{i+p} - Y_bar) where X_bar and Y_bar are the mean estimates: X_bar = 1/N * sum_{i=1}^{N} X_{i} Y_bar = 1/N * sum_{i=1}^{N} Y_{i} It satisfies the following identities: 1. variance consistency: if acv = autocov(X,X), then acv(1,1) = var(X) 2. covariance consistence: if acv = autocov(X,Y), then acv(1,1) = cov(X,Y)
