Fifthly , a texture description and accessing algorithm based on the variogram function is introduced 提出了一個(gè)基于variogram函數(shù)的紋理圖象分析和檢索方法。
The image is divided to different parts by result that the image is analyzed by the variogram function 通過(guò)應(yīng)用變差函數(shù)來(lái)分析圖像上不同區(qū)域的性質(zhì),作為圖像劃分區(qū)域依據(jù)。
The rnultiscale edge detection and texture image segmentation are studied based on the variogram function 我們基于變差函數(shù)的這種性質(zhì)對(duì)圖像的多尺度邊緣檢測(cè)和紋理分割作了較為深入的研究。
Generally , the calculation of semi - variogram calls for data to conform to normal distribution , or it will cause proportion effects 變異函數(shù)的計(jì)算一般要求數(shù)據(jù)符合正態(tài)分布,否則可能會(huì)使變異函數(shù)產(chǎn)生比例效應(yīng)。
The variogram function comes from linear geological statistics , which exhibits not only the stochastic but also the structural properties of image data 變差函數(shù)是線性地質(zhì)統(tǒng)計(jì)學(xué)中的概念,它不僅反映了圖像數(shù)據(jù)的結(jié)構(gòu)性,而且還反映圖像數(shù)據(jù)的隨機(jī)性。
Spherical models , exponential models , gaussian models can be used to fit the semi - variogram . draft phenomena of available iron showed hole effect model 其變異函數(shù)可用球狀模型、指數(shù)模型、高斯模型擬合,有效鐵存在漂移現(xiàn)象,可用孔穴效應(yīng)模型擬合。
In this di ssertation , segmentation , description and recognition of objects are studied systematically by the variogram function and implicit polynomial ( ip ) curve 本文引進(jìn)變差函數(shù)和隱含多項(xiàng)式曲線理論對(duì)景物圖像中的物體分割、描述和識(shí)別作了較為系統(tǒng)的研究。
At the same time , according to the excellent capability of ip curves , we study fitting and description of objects , determination of invariants of objects , symmetry detection and recognition of objects based on ip curves . in all , the main contributions in the dissertation are as follows : ( 1 ) a method of determining automatically the scale of the multiscale edge detection is proposed based on the variant distance of the variogram function , and a method of segmenting texture images is also presented . the variograin values are taken as stochastic and structural properties of texture images and variant distance is taken as the size of image window 同時(shí),基于隱含多項(xiàng)式曲線良好的物體描述與識(shí)別能力,對(duì)物體邊界輪廓的擬合、描述、不變量特征的提取、識(shí)別以及物體對(duì)稱性檢測(cè)作了系統(tǒng)的研究,主要成果及創(chuàng)新之處有: ( 1 )基于變差函數(shù)的變程,提出了圖像多尺度邊緣檢測(cè)中尺度大小的自動(dòng)確定方法;將變差函數(shù)的變差值作為紋理的統(tǒng)計(jì)和結(jié)構(gòu)特征,依據(jù)變程確定窗口大小,給出一種新的紋理圖像的分割方法。
