DCFirst Claim
Patent Images
1. A method of classifying regions of image pixels in a digital image or video captured by an image capture device comprising:
- a) providing a geographic location determining device associated with the image capture device that provides an image capture GPS location associated with an image;
b) using the location determining device to provide the image capture GPS location at substantially the time that the digital image or video was captured; and
c) using a data processor for classifying regions of image pixels in the captured digital image or video into one or more material classes based on a spatial context model that indicates the likelihood that specific material classes occur or co-occur in images or videos captured at the particular image capture GPS location.

Abstract
A method of classifying regions in a digital image or video captured by an image capture device includes providing a geographic location determining device associated with the image capture device; using the location determining device to measure the image capture location at substantially the time that the digital image or video was captured; and classifying regions in the captured digital image or video into one or more classes based on the image-capture location.

14. A method of enhancing regions of image pixels in a digital image or a video frame captured by an image capture device comprising:
-
a) providing a geographic location determining device associated with the image capture device that provides an image capture GPS location associated with an image; b) using the geographic location determining device to provide the image capture GPS location at substantially the time that the digital image or video was captured; c) using a data processor for classifying regions of image pixels in the captured digital image or video into one or more classes based on a spatial context model that indicates the likelihood that specific classes occur or co-occur in images or videos captured at the particular image capture GPS location; and d) applying image enhancement to classified regions of image pixels depending on the class of each region.

15. A method of searching in a database a digital image or a video frame captured by an image capture device comprising:
-
a) providing a geographic location determining device associated with the image capture device that provides an image capture GPS location associated with an image; b) using the geographic location determining device to provide the image capture GPS location at substantially the time that the digital image or video was captured; c) using a data processor for classifying regions of image pixels in the captured digital image or video into one or more classes based on a spatial context model that indicates the likelihood that specific classes occur or co-occur in images or videos captured at the particular image capture GPS location, storing the classified regions of image pixels in a database; and d) searching in the database for images containing regions of image pixels of one or more pre-determined classes.
