Pattern matching method using a pyramid structure search, image detecting device, and computer-readable medium
First Claim
1. A pattern matching method using a pyramid structure search of searching a predetermined pattern image, which is previously registered, from an input image as a search object by using the pyramid structure search, comprising:
- calculating a plurality of groups of set parameter candidates to execute the pyramid structure search;
calculating indexes indicating features of respective groups of set parameter candidates;
displaying the plurality of groups of set parameter candidates that are calculated, wherein said displaying simultaneously displays the indexes with the respective groups of set parameter candidates, and wherein at least one of the plurality of groups of set parameter candidates comprises a reduction ratio; and
selecting, by a user, one of the plurality of groups of set parameter candidates, to execute the pyramid search.

Abstract
An image detecting device for executing a pattern matching using a pyramid structure search, comprises an input image storing portion for receiving image data from an external device to hold, a pattern image storing portion for storing a pattern image to be searched, an image processing portion connected to the input image storing portion and the pattern image storing portion, for reading respective image data to execute the pattern matching, a control portion for calculating set parameter candidates that are required to execute the pyramid structure search in the image processing portion, a display portion for displaying groups of set parameter candidates that are calculated in the control portion as a table, and an input portion used to change set parameter values based on the groups of set parameter candidates displayed on the display portion.

5. An image detecting device for executing a pattern matching using a pyramid structure search, comprising:
-
an input image storing portion for storing an input image data provided from an external device; a pattern image storing portion for storing a pattern image data to be searched; an image processing portion connected to the input image storing portion and the pattern image storing portion, for reading the input image data and the pattern image data to execute the pattern matching; a control portion for calculating a plurality of groups of set parameter candidates that are required to execute the pyramid structure search by the image processing portion and for calculating indexes indicating features of respective groups of set parameter candidates; a display portion for displaying the plurality of groups of set parameter candidates, which are calculated by the control portion, wherein said displaying simultaneously displays the indexes with the respective groups of set parameter candidates, and wherein at least one of the plurality of groups of set parameter candidates comprises a reduction ratio; and an input portion for receiving a selection, by a user, of one of the plurality of groups of set parameter candidates, to execute the pyramid search. - View Dependent Claims (6, 7, 8, 16)

9. A computer-readable medium including a program executable on a computer for executing a pattern matching using a pyramid structure search, said program comprising instructions having:
-
a first function of storing an input image data; a second function of storing a pattern image data to be searched; a third function of reading the input image data arid the pattern image data to execute the pattern matching; a fourth function of calculating a plurality of groups of set parameter candidates that are required to execute the pyramid structure search, wherein at least one of the plurality of groups of set parameter candidates comprises a reduction ratio; a fifth function of calculating indexes indicating features of respective groups of set parameter candidates; a sixth function of displaying the calculated plurality of the groups of set parameter candidates, wherein said displaying simultaneously displays the indexes with the respective groups of set parameter candidates; and a seventh function of receiving a selection, by a user, of one of the plurality of groups of set parameter candidates, to execute the pyramid search. - View Dependent Claims (10, 17)
