Method of describing pattern repetitiveness of image
First Claim
1. A method of describing pattern repetitiveness of an image comprising the steps of:
- (a) projecting an image on a predetermined axis having a predetermined direction;
(b) decomposing the projected image down one level;
(c) increasing a threshold value until a pattern quantizing value is retained, and denoising the decomposed data; and
(d) describing pattern repetitiveness of the image using the pattern quantizing value of the denoised data and the threshold value used for denoising.

Abstract
A method for describing pattern repetitiveness which may exist within an image, is provided. The method of describing pattern repetitiveness of an image comprises: (a) projecting an image on a predetermined axis having a predetermined direction, (b) decomposing the projected image down one level, (c) increasing a threshold value until a pattern quantizing value is retained, and denoising the decomposed data, and (d) describing pattern repetitiveness of the image using the pattern quantizing value of the denoised data and the threshold value used for denoising. Because the method of describing pattern repetitiveness of an image effectively denoises the original image without damaging the pattern repetitiveness of the original image, and the pattern repetitiveness is described using the denoised data, it is possible to describe more definite pattern repetitiveness.

5. A pattern repetitiveness describing method of an image comprising the steps of:
-
(a) projecting an image on a predetermined axis having a predetermined direction;
(b) decomposing the image until the level at which a previous pattern quantizing value and a pattern quantizing value after the decomposition are retained as they are, and denoising; and
(c) describing the pattern repetitiveness of the image using one of the pattern quantizing value of the data from which at least level number and noise are removed, and the threshold value used for denoising. - View Dependent Claims (6, 7, 8)

9. A method of grouping images having similar texture characteristics within an image database in which a plurality of images are stored, the method comprising the steps of:
-
(a) projecting an image on a predetermined axis having a predetermined direction;
(b) decomposing the projected image down one level;
(c) increasing a threshold value until a pattern quantizing value is retained, and denoising the decomposed data;
(d) determining pattern repetitiveness vectors including the pattern quantizing value of the denoised data and the threshold value used for denoising as pattern repetitiveness descriptors of images; and
(e) grouping images having similar texture characteristics using the pattern repetitiveness descriptors of the images.
