pattern n. 1.模范,榜樣;典范。 2.型,模型;模式;雛型;【冶金】原型。 3.花樣;式樣;(服裝裁剪的)紙樣;圖案,圖譜,圖表;機構(gòu),結(jié)構(gòu);特性曲線;晶體點陣;(電視的)幀面圖像。 4.方式;形式;格局;格調(diào)。 5.(衣料等的)樣品,樣本,樣板。 6.〔美國〕一件衣料。 7.(炮彈等的)散布面;靶子上的彈痕。 8.(飛機的)著陸航線。 a pattern wife 模范妻子。 a paper pattern for a dress 女服紙樣。 a machine of a new [an old] pattern新[舊]型機器。 a cropping pattern農(nóng)作制。 after the pattern of 仿…。 vt. 1.照圖樣做;仿造,摹制 (after; upon)。 2.給…加花樣,用圖案裝飾。 3.〔英方〕與…相比 (to, with)。 vi. 形成圖案。 pattern oneself after 模仿,學(xué)…的榜樣。 adj. -ed 仿造的;被組成圖案的(patterned forms【語言學(xué)】 仿造詞)。 n. -ing 圖案結(jié)構(gòu),圖形;(行為等的)特有型式。 adj. -less 無圖案的。
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,針對局部二進制模板紋理分割速度較慢的問題,本文一方面調(diào)整了模板算子的計算方式,另一方面將單一門限的區(qū)域合并改進為雙門限合并。
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,以實值模式代替二值模式,避免了實值到二值的編碼過程:以回歸學(xué)習(xí)規(guī)則代替外積法,使該模型在具有識別能力的同時具有了對函數(shù)的逼近能力;地址矩陣的預(yù)置根據(jù)樣本的分布采取不同方法,若樣本均勻分布,則隨機預(yù)置,否則利用遺傳算法的原理和消減措施來預(yù)置地址矩陣,使之反映樣本的分布,改善網(wǎng)絡(luò)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變換結(jié)合的水印方案算法以二值圖標(biāo)或灰度圖標(biāo)作為水印,將原圖像和水印信號分別進行不同層次的小波分解,分解后的水印各分量偽隨機置亂后分別嵌入到原圖像相應(yīng)分解層各分量的dct域中。
