First Claim
Patent Images
1. A method comprising:
- generating first and second pseudorandom numbers;
extracting a first feature of an image based on the first and second pseudorandom numbers, wherein extracting the first feature of the image comprises;
identifying a location of a region of the image based on the first and second pseudorandom numbers; and
computing an average of pixels of the identified region;
determining whether a classification for the image is known; and
in response to a known classification of the image, updating a classification model used to classify a second image.

9. An apparatus comprising:
-
a pseudorandom number generator to generate one or more pseudorandom numbers; a feature extractor to extract a first feature of an image based on the one or more pseudorandom numbers by identifying a region of the image based on the one or more pseudorandom numbers and computing an average of pixels of the identified region; an image classifier to determine whether a classification for the image is known, and in response to a known classification of the image, updating one or more classification parameters, wherein the one or more classification parameters are used to classify a second image. - View Dependent Claims (10, 11, 12, 13, 14)

15. A tangible computer readable storage device or storage disc comprising machine-readable instructions which, when executed, cause a machine to at least:
-
generate one or more pseudorandom numbers; extract a first feature of an image based on the one or more pseudorandom numbers by identifying a region of the image based on the one or more pseudorandom numbers and computing an average of pixels of the identified region; determine whether a classification for the image is known; and in response to a known classification of the image, update one or more classification parameters, wherein the one or more classification parameters are used to classify a second image. - View Dependent Claims (16, 17, 18, 19, 20)
