Title:
IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD, AND PROGRAMME
Document Type and Number:
WIPO Patent Application WO/2011/158536
Kind Code:
A1
Abstract:
Disclosed are a programme, an image processing method and an image processing device capable of quickly extracting characteristic regions. The disclosed image processing device is provided with an initial contour arrangement means, which uses a level-set function to arrange an initial contour on a digital image, and the device extracts characteristic regions from the image by altering the initial contour by means of a level-set method. The initial contour arrangement means forms the initial contour by means of a plurality of contours, arranges so that at least one point in each of the plurality of contours touches another contour, and makes the initial value of the level-set function the unsigned shortest distance from each point on the image to the initial contour.
