IMAGE RECOGNITION METHOD AND IMAGE RECOGNITION APPARATUS
First Claim
1. An image recognition method comprising:
- a first extracting step of extracting, from every registration image which is previously registered, a set of registration partial images of a predetermined size;
a second extracting step of extracting, from an input new image, a set of new partial images of a predetermined size;
a discriminating step of discriminating an attribute of the new partial image based on a rule which is formed by dividing the set of the registration partial images extracted in the first extracting step; and
a collecting step of deriving a final recognition result of the new image by collecting discrimination results in the discriminating step at the time when the new partial images as elements of the set of the new partial images are input.

Abstract
An image recognition apparatus is provided which comprises a first extracting means for extracting, from every registration image previously registered, a set of registration partial images of a predetermined size, and a second extracting means for extracting, from an input new image, a set of new partial images of a predetermined size. The apparatus further comprises a discriminating means for discriminating an attribute of the new partial image based on a rule formed by dividing the set of the registration partial images extracted by the first extracting means, and a collecting means for deriving a final recognition result of the new image by collecting discrimination results by the discriminating means at the time when the new partial images as elements of the set of the new partial images are input.

9. An image recognition method comprising:
-
an extracting step of extracting a partial image from an input image; a discriminating step of discriminating to which partial image of which category that has previously been learned the partial image belongs; a voting step of voting based on a discrimination result in the discriminating step; a collecting step of collecting voting results obtained by repeating the extracting step, the discriminating step, and the voting step; and an identifying step of identifying a position and a category of an object existing in the input image based on a collection result in the collecting step. - View Dependent Claims (10, 11, 12, 13, 14)

15. An image recognition apparatus comprising:
-
a first extracting unit configured to extract, from every registration image which is previously registered, a set of registration partial images of a predetermined size; a second extracting unit configured to extract, from an input new image, a set of new partial images of a predetermined size; a discriminating unit configured to discriminate an attribute of the new partial image based on a rule which is formed by dividing the set of the registration partial images extracted by the first extracting unit; and a collecting unit configured to derive a final recognition result of the new image by collecting discrimination results by the discriminating unit at the time when the new partial images as elements of the set of the new partial images are input.

16. An image recognition apparatus comprising:
-
an extracting unit configured to extract a partial image from an input image; a discriminating unit configured to discriminate to which partial image of which category that has previously been learned the partial image belongs; a voting unit configured to vote based on a discrimination result by the discriminating unit; a collecting unit configured to collect voting results obtained by repeating processing by the extracting unit, the discriminating unit, and the voting unit; and an identifying unit configured to identify a position and a category of an object existing in the input image based on a collection result by the collecting unit.
