Computationally Efficient Scene Classification
First Claim
1. A computer-implemented method comprising:
- determining partition regions for an image depicting a scene;
receiving image data including pixels forming the image;
classifying pixels of the image into one or more pixel types based on one or more pixel-level features;
determining, for each partition region, a set of pixel characteristic data describing a portion of the image included in the partition region based on the one or more pixel types of pixels in the partition region; and
classifying the scene of the image based on the set of pixel characteristic data of each of the partition regions.

Abstract
The disclosure describes novel technology for inferring scenes from images. In one example, the technology includes a system that can determine partition regions from one or more factors that are independent of the image data, for an image depicting a scene; receive image data including pixels forming the image; classify pixels of the image into one or more pixel types based on one or more pixel-level features; determine, for each partition region, a set of pixel characteristic data describing a portion of the image included in the partition region based on the one or more pixel types of pixels in the partition region; and classify a scene of the image based on the set of pixel characteristic data of each of the partition regions.
