Using camera metadata to classify images into scene type classes
First Claim
1. An image processing method, comprising:
- obtaining a metadata-based classification result based on metadata associated with an image;
determining a histogram-based classification result based on a histogram of intensity values derived from the image; and
classifying the image into a scene type class based on the metadata-based classification result and the histogram-based classification result.

Abstract
In one aspect, a metadata-based classification result is obtained based on metadata associated with an image. A histogram-based classification result is determined based on a histogram of intensity values derived from the image. The image is classified into a scene type class based on the metadata-based classification result and the histogram-based classification result. In another aspect, a first condition is applied on a first one of metadata associated with an image corresponding to a measure of amount of light received in capturing the image to obtain a first metadata-based classification result. A second condition is applied on a second one of the metadata corresponding to a measure of brightness of the image to obtain a second metadata-based classification result. The image is classified into a scene type class based on the first and second metadata-based classification results.

11. An image processing system, comprising:
-
a metadata-based scene type classifier that performs an initial classification of an image into a scene type class based on metadata associated with the image; and
a verification classifier that verifies the initial classification of the image into the scene type class based on a histogram of intensity values derived from the image. - View Dependent Claims (12, 13, 14, 15, 16, 17)
