Abstract:
1. A region extraction method, by an image processing apparatus, for extracting a specified region in an image, the method including the steps of: (a) displaying the image; (b) selecting a desired region in the image; (c) selecting an element graphic corresponding to at least a partial contour of a partial region in the desired region; (d) approximating at least a rectifiable partial contour of the selected element graphic to at least said partial contour of the partial region; (e) repeating the steps (c) to (d) at least twice, so that at least two selected element graphics overlap with each other; and (f) making a first closed contour by combining at least said rectifiable partial contour of the respective element graphics after the approximation; (j) obtaining, by the image processing apparatus, a second closed contour similar to the first closed contour by enlarging or reducing the first closed contour; and (k) extracting, by the image processing apparatus, a region including a stratified region held between the first closed contour and the second closed contour.
