Patent Images
1. A system for selectively generating training data for a pattern recognition classifier from a plurality of training images representing an output class, said system comprising:
- an image synthesizer that combines the plurality of training images into a class composite image;
a grid generator that generates a grid pattern representing the output class from the class composite image; and
a feature extractor that extracts feature data from the plurality of training images according to the generated grid pattern.

Abstract
A system (600) for selectively generating training data for a pattern recognition classifier includes an image synthesizer (606) that combines a plurality of training images from an output class into a class composite image. A grid generator (608) generates a grid pattern representing the output class from the class composite image. A feature extractor (610) extracts feature data from the plurality of training images according to the generated grid pattern.

19. A method for selectively generating training data for a pattern recognition classifier from a plurality of training images representing a desired output class, said method comprising the steps of:
-
generating a representative image that represents the output class;
dividing the representative image according to an initial grid pattern to form a plurality of sub-images;
identifying at least one sub-image formed by said grid pattern having at least one attribute of interest;
modifying said grid pattern in response to the identified at least one sub-image having said at least one attribute of interest so as to form a modified grid pattern; and
using the modified grid pattern to extract respective feature vectors from the plurality of training images. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28)
