[0048] Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

[0049] The image processing device according to the first embodiment is a device that, after acquiring an image such as a photograph and acquiring a feature value corresponding to the image, recognizes a target object included in the image. figure 1 It is a system configuration diagram of the image processing device 10 according to this embodiment.

[0050] The image processing device 10 is composed of an image acquisition unit 11 , a feature acquisition unit 12 , a feature correction unit 13 , an image recognition unit 14 , and an input / output unit 15 .

[0051]The image acquisition unit 11 is a means for acquiring an image to be processed, and in this embodiment is a storage device such as a fixed disk drive or a flash memory. In addition, the image acquisition unit 11 may be a component that acquires an image from outside the device (for example...

no. 2 approach

[0090] In the first embodiment, the value calculated based on the luminance value of the pixel is directly used as the feature amount. In contrast, the second embodiment is an embodiment in which a value encoded based on a brightness value of a pixel is used as a feature value. The configuration of the image processing device according to the second embodiment is the same as that of the first embodiment, so detailed description will be omitted, and only differences will be described.

[0091] First, a case where encoded values ​​are used as feature quantities will be described. Here, a method of calculating feature quantities using a method called FAST is exemplified.

[0092] FAST (Features from Accelerated Segment Test) is a method for detecting a corner of a target object. In FAST, it is determined whether the pixels on the circumference surrounding the pixel of interest are brighter or darker than the pixel of interest, and when the same determination continues for a pre...

Abstract

Provided is an image processing apparatus according to which, even when a relationship between the magnitudes of brightness values of objects that belong to the same category is inverted, feature amounts that are similar to the extent that the objects can be recognized as belonging to the same category are acquired. The image processing apparatus includes an image acquiring unit (11) configured to acquire an image, and a feature amount acquiring unit (12, 13) configured to acquire feature amounts that correspond to the acquired image by performing a predetermined arithmetic operation on the image, and to output the acquired feature amount, wherein when the acquired feature amounts include a negative value, the feature amount acquiring unit replaces the negative value with the absolute value of the negative value.

Description

technical field [0001] The invention relates to an image processing device for image recognition. Background technique [0002] Image recognition technology that recognizes an object contained in an image based on inherent information obtained from the image such as color or shape is widely spread. [0003] Often used in image recognition devices is a method of obtaining a feature quantity corresponding to an image by using pixel brightness information, and identifying a target object based on the feature quantity. The feature amount expresses, in numerical value, an inherent feature of an object of identification purpose. [0004] As one of techniques for recognizing a target object using feature quantities, there is an image recognition device described in Patent Document 1, for example. In this image recognition device, a pair of two feature quantities is obtained from an image and encoded, and the results calculated at multiple places are combined to calculate a featur...
