Abstract
A region-extraction method for extracting a contour of a desired region is provided. The method includes: a step (a) for displaying an image; a step (b) for selecting a desired region in the image; a step (c) for selecting an element graphic corresponding at least a partial contour in a partial region in the desired region; a step (d) for approximating the contour of a part of the element image to at least a partial contour in the partial region; a step (e) for repeating the steps (c) to (d) at least twice; and a step (f) for making a first contour by combining at least a part of elements after the approximation.

A region extraction method for extracting a specified region in an image including:
- (a) a step for displaying the image;
- (b) a step for selecting a desired region in the image;
- (c) a step for selecting an element graphic corresponding to at least a partial contour of a partial region in the desired region;
- (d) a step for approximating at least a partial contour of the element graphic to at least a partial contour in the partial region;
- (e) a step for repeating the steps (c) to (d) at least twice;
- and
- (f) a step for making a first contour by combining at least a partial contour of the respective element graphics after the approximation.
The region extraction method for extracting a specified region in an image including:
- (l) a step for displaying the image;
- (m) a step for selecting a desired region in the image;
- (n) a step for extracting one or more partial regions from the desired region;
- (o) a step for combining the one or more partial regions and synthesizing at least parts of the desired region;
- and
- (p) a step for making at least a partial contour of the desired region of at least the partial region being synthesized as a first contour.
A region extraction device comprising:
- a display means for displaying an image;
- an input means for receiving the command relating to the image;
- and
- a calculating means for executing a desired image processing relating to the image, wherein:
- the display means displays a plurality of element graphics along with the image;
- the input means receives the command for approximating at least a partial contour of the respective element graphics to at least a partial contour of the desired region;
- and
- the calculation means makes a contour by which at least a partial contour of the respective element graphics after the approximation is combined as a first contour.
