Fifthly , a texture description and accessing algorithm based on the variogram function is introduced 提出了一個基于variogram函數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 通過應用變差函數來分析圖像上不同區域的性質,作為圖像劃分區域依據。
The rnultiscale edge detection and texture image segmentation are studied based on the variogram function 我們基于變差函數的這種性質對圖像的多尺度邊緣檢測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 變異函數的計算一般要求數據符合正態分布,否則可能會使變異函數產生比例效應。
The variogram function comes from linear geological statistics , which exhibits not only the stochastic but also the structural properties of image data 變差函數是線性地質統計學中的概念,它不僅反映了圖像數據的結構性,而且還反映圖像數據的隨機性。
Spherical models , exponential models , gaussian models can be used to fit the semi - variogram . draft phenomena of available iron showed hole effect model 其變異函數可用球狀模型、指數模型、高斯模型擬合,有效鐵存在漂移現象,可用孔穴效應模型擬合。
In this di ssertation , segmentation , description and recognition of objects are studied systematically by the variogram function and implicit polynomial ( ip ) curve 本文引進變差函數和隱含多項式曲線理論對景物圖像中的物體分割、描述和識別作了較為系統的研究。
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,基于隱含多項式曲線良好的物體描述與識別能力,對物體邊界輪廓的擬合、描述、不變量特征的提取、識別以及物體對稱性檢測作了系統的研究,主要成果及創新之處有: ( 1 )基于變差函數的變程,提出了圖像多尺度邊緣檢測中尺度大小的自動確定方法;將變差函數的變差值作為紋理的統計和結構特征,依據變程確定窗口大小,給出一種新的紋理圖像的分割方法。
