Secondly , texture segmentation based on local binary pattern ( lbp ) texture descriptor is very time consuming . for one thing , we adjust the computing method of lbp , for another , set two merging threshold instead of only one 第二,针对局部二进制模板纹理分割速度较慢的问题,本文一方面调整了模板算子的计算方式,另一方面将单一门限的区域合并改进为双门限合并。
In rsdm , binary patterns are replaced by real - valued patterns , accordingly avoiding the coding process ; the outer learning rule is replaced by regression rule , therefore the model has not only the ability of pattern recognition but the ability of function approximation . the prearrangement of the address array bases on the distribution of patterns . if the distribution of patterns is uniform . then the address array is prearranged randomly , otherwise predisposed with the theory of genetic algorithm and the pruneing measure so as to indicate the distribution of patterns and improve the network performance . non - linear function approximation , time - series prediction and handwritten numeral recognition show that the modified model is effective and feasible 在rsdm中,以实值模式代替二值模式,避免了实值到二值的编码过程:以回归学习规则代替外积法,使该模型在具有识别能力的同时具有了对函数的逼近能力;地址矩阵的预置根据样本的分布采取不同方法,若样本均匀分布,则随机预置,否则利用遗传算法的原理和消减措施来预置地址矩阵,使之反映样本的分布,改善网络的性能。
The watermarking scheme based on wavelet decomposition and discrete cosine transform using a binary pattern or gray - level pattern as the watermark , the scheme initially performs wavelet decomposition of the host image and the watermark with different hierarchy . after the pseudo - random permutation , each decomposed layer of the watermark is embedded into the dct domain of corresponding decomposed layer of the host image 基于小波分解和余弦变换结合的水印方案算法以二值图标或灰度图标作为水印,将原图像和水印信号分别进行不同层次的小波分解,分解后的水印各分量伪随机置乱后分别嵌入到原图像相应分解层各分量的dct域中。
