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

An image processing system comprising an image processing apparatus configured to extract an object region from an image, the image processing apparatus comprising:

• a setting unit configured to set a plurality of reference points in the image;
• an obtaining unit configured to obtain a contour of the object region corresponding to each of the plurality of reference points as an initial extraction result based on a characteristic of the object region;
• and
• an extraction unit configured to extract the object region from the image based on an integration result obtained by integrating values of pixels in a plurality of initial extraction results.

An image processing method of an image processing apparatus configured to extract an object region from an image, comprising:

• setting a plurality of reference points in the image;
• obtaining a contour of the object region corresponding to each of the plurality of reference points as an initial extraction result based on a characteristic of the object region;
• and
• extracting the object region from the image based on an integration result obtained by integrating values of pixels in a plurality of initial extraction results.

A storage medium storing a program configured to cause a computer to execute each step of an image processing method of an image processing apparatus configured to extract an object region from an image, the image processing method comprising:

• setting a plurality of reference points in the image;
• obtaining a contour of the object region corresponding to each of the plurality of reference points as an initial extraction result based on a characteristic of the object region;
• and
• extracting the object region from the image based on an integration result obtained by integrating values of pixels in a plurality of initial extraction results.
