Image processing apparatus, image processing method, and storage medium of image processing method

摘要

An image region extracting unit binarizes image data inputted from an image inputting unit and labels the binarized image data based upon a feature value of a pixel to be segmentized into a plurality of image regions. A contour connection determining unit 104 determines whether or not connection points connecting contour lines of the respective image regions extracted by a contour extracting unit each other exist. A contour modifying unit, when it is determined that the connection points exist by the contour connection determining unit, connects the contour lines each other at the connection points to modify the contour line.

主权项

1. An image processing apparatus comprising:
an extraction unit configured to extract, from a connected component, a first outer contour line, a first inner contour line and a second inner contour line of the connected component; a determination unit configured to determine two points where the extracted first inner contour line and the extracted second inner contour line are connected; a division unit configured to divide the extracted first inner contour line at the determined two points into two contour lines, and divide the extracted second inner contour line at the determined two points into two contour lines; a generation unit configured to generate a third inner contour line by combining one of the two lines obtained by the dividing of the extracted first inner contour line and one of the two lines obtained by the dividing of the extracted second inner contour line, and generate a second outer contour line by combining the other of the two lines obtained by the dividing of the extracted first inner contour line and the other of the two lines obtained by the dividing of the extracted second inner contour line; and a function approximation unit configured to perform a respective function approximation using each of the extracted first outer contour line, the generated third inner contour line, and the generated second outer contour line.
