Object identifier
First Claim
Patent Images
1. An object identifying apparatus comprising:
- an image capturing unit that is mounted on a vehicle for acquiring an original image by capturing the original image while the vehicle is traveling;
a data generator for successively integrating pixel values of integration object images representing feature quantities at respective pixels that make up the original image, from a starting point at either one of angular positions of the integration object images, thereby generating integral images, each including an image area having a size in common with the original image and the integration object images;
a data acquirer for acquiring compressed data by extracting at least every other pixel along at least one direction from a plurality of pixels that make up the integral images generated by the data generator;
an identification object region determiner for determining an identification object region from within an original image area represented by the original image; and
an object identifier for calculating a total of the pixel values of the integration object images within the identification object region that was determined by the identification object region determiner, as an image feature quantity using the compressed data acquired by the data acquirer, and on the basis of the image feature quantity, identifying whether or not an object exists within the identification object region in the original image,wherein the image feature quantity is represented by a histogram.

Abstract
An object identifier is provided with a data-forming unit and a data-retrieving unit. The data-forming unit forms an integral image having an image region of the same size as an original image and an image to be integrated. The data-retrieving unit obtains compressed data derived by extracting, from a plurality of pixels constituting the integral image, at least every other pixel in at least one direction.
