基于扩频技术的数字水印matlab源代码。大家共享之(Spread-spectrum technology based on digital watermarking matlab source code. U.S. share of)

removal of both powerline interference and base line wander

使用中科院虹膜数据库，实现了虹膜内外边界定位(Iris database using the Chinese Academy of Sciences, to achieve both inside and outside the iris boundary localization)

说明：  k均值算法，社区划分算法中经典算法，WSN中分簇也可使用该算法。(K-means algorithm, classic algorithms in community partition algorithm, clustering can also use this algorithm in the WSN.)

Assume that a direct sequence spread spectrum system uses the Barker code of length 7 (N=7) as its spreading sequence. a. Randomly generate 8 symbols (d0~d7) from the set {+1,-1}. b. If each chip of the Barker code is denoted as cj, j=0~6, spread each symbol di by the Barker code. (Please refer to p. 17 of the slides.) Use “stem” to plot the signals before spreading and after spreading
