Texture-based image database browsing and sorting method

Abstract

A texture-based image database browsing and sorting method computes the number of edge pixels of objects in static images, measures textures of the static images by numerating the number of edge pixels thereof and measures a texture of a query image by numerating the number of edge pixels of an object in the query image. Then, the method sorts the measured textures according to a sorting order and searches a texture close to the texture of the query image among the sorted textures.

1 . A method for sorting static images, comprising the steps of: 
 counting a number of edge pixels of objects in each of the static images to measure a texture of each of the static images, the measured texture of each of the static images being defined as the counted number of edge pixels of objects in each of the static images; and    sorting the static images based on the measured textures of each of the static images.    
   
   
       2 . The method of  claim 1 , wherein the step of measuring includes the steps of: 
 performing an n-dimensional Wavelet transform by using a high pass filter so as to obtain transformed static images; and    performing a Soble operator in order to eliminate noises included in the transformed static images and counting the number of edge pixels of the objects in the transformed static images.    
   
   
       3 . The method of  claim 1 , wherein the step of sorting sorts the measured textures such that values thereof are in an order of closeness to a texture value of a newly inputted texture.  
   
   
       4 - 5 . (canceled)  
   
   
       6 . A method for sorting static images, comprising the steps, in the following order, of: 
 a) performing an n-dimensional Wavelet transfor for transforming the static images by using a high pass filter;    b) performing a Sobel operator for eliminating noise included in the transformed static images;    c) counting edge pixels of objects in each of the static images;    d) representing a texture of each of the static images with a numeric value representing the counted number of edge pixels; and    e) sorting the static images according to the numeric values of the static images; respectively.
