Information processing apparatus and method as well as medium

An image processing method, comprising:

• a first inputting step of inputting an image picked up by a base image pickup apparatus as a base image;
• a second inputting step of inputting at least one image picked up by at least one reference image pickup apparatus disposed at a different visual point from the base image pickup apparatus as a reference image or images;
• a setting step of setting an arbitrary object pixel and peripheral pixels around the object pixel from among pixels of the base image as a template;
• a production step of producing a plurality of deformed templates via linear interpolation based on a shape of the template set by the processing in the setting step;
• and
• a calculation step of determining a corresponding point or points of the reference image or images on an associated epipolar line using the deformed templates to calculate a corresponding relationship of the reference image or images to the base image, wherein the calculation step calculates similarity degrees of the deformed templates at pixels of the reference image or images and extracts and sets a coordinate point which exhibits a highest correlation from among the calculated similarity degrees as a corresponding point.

A medium for causing a computer to execute a program which includes:

• a first inputting step of inputting an image picked up by a base image pickup apparatus as a base image;
• a second inputting step of inputting at least one image picked up by at least one reference image pickup apparatus disposed at a different visual point from the base image pickup apparatus as a reference image or images;
• a setting step of setting an arbitrary object pixel and peripheral pixels around the object pixel from among pixels of the base image as a template;
• a production step of producing a plurality of deformed templates via linear interpolation based on a shape of the template set by the processing in the setting step;
• and
• a calculation step of determining a corresponding point or points of the reference image or images using the deformed templates to calculate a corresponding relationship of the reference image or images to the base image, wherein the calculation step calculates similarity degrees of the deformed templates at pixels of the reference image or images and extracts and sets a coordinate point which exhibits a highest correlation from among the calculated similarity degrees as a corresponding point.
