Abstract
Information indicating the reason for a failure of template matching is provided. Difference information between a first image, which is referred to as a template, and a third image that is selected by the operator from a second image and that is larger than the template is displayed.
Claims17
An image processing device comprising:
- a memory for storing a template for pattern matching and an image of a subject;
- a display unit for displaying the template and the image of the subject;
- a region specifying device for specifying a region which includes a first region detected by the pattern matching and a second region including an actually desired pattern to be detected in the image of the subject;
- and
- an image processing unit for computing first degree of coincidence between the first region and the template and second degree of coincidence between the second region and the template, wherein the display unit displays the first degree of coincidence and second degree of coincidence.

An image processing device comprising:
- a display unit for storing a template image for pattern matching and an image of a subject;
- a region specifying device for specifying an objective area in a searched area of the image which is carried out by the pattern matching;
- and
- an image processing unit for selectively carrying out the pattern matching in the objective area and computing degree of coincidence between the template and a part of the objective area, wherein the display unit displays the degree of coincidence.

An image processing device comprising:
- a memory for storing a template image for pattern matching and an image of a subject;
- a display unit for displaying the template as a semitranslucent image and a searched area of the pattern matching;
- an input unit for moving the template in the searched area;
- and
- an image processing unit for computing degree of coincidence between the template moved by the input device and a part of the searched area superimposing to the template.
