Abstract:
1. An object recognizing apparatus comprising: an area acquiring unit configured to detect object area images of an object to be recognized from a degraded image which is degraded by blur; a feature vector generating unit configured to generate a feature vector by converting the object area images respectively to frequency areas and extracting a feature vector indicating the amount of blur; a storage unit configured to generate a plurality of blurred images by applying a plurality of point spread functions stored in advance individually to a plurality of training images without blur stored in advance, group the plurality of blurred images generated by the plurality of point spread functions into clusters, and store the respective clusters therein in one-to-one correspondence with the respective point spread functions; an estimating unit configured to compare the feature vector and the plurality of burred images belonging to the respective clusters by a pattern recognition, obtain a cluster which is most similar to the feature vector, and select one of the point spread functions which corresponds to the most similar cluster; a restoring unit configured to restore the object area image into the image before blurred using the selected point spread function; and an identifying unit configured to compare the restored image and the target image to identify the object.
