Abstract
A system and method for detecting objects and background in digital images using range information includes receiving the digital image representing a scene; identifying range information associated with the digital image and including distances of pixels in the scene from a known reference location; generating a cluster map based at least upon an analysis of the range information and the digital image, the cluster map grouping pixels of the digital image by their distances from a viewpoint; identifying objects in the digital image based at least upon an analysis of the cluster map and the digital image; and storing an indication of the identified objects in a processor-accessible memory system.
Claims16
A method for detecting objects and background in a digital image, and the method implemented at least in part by a data processing system and comprising the steps of:
- receiving the digital image representing a scene;
- identifying range information associated with the digital image, the range information including distances of pixels in the scene from a known reference location;
- generating a cluster map based at least upon an analysis of the range information and the digital image, the cluster map grouping pixels of the digital image by their distances from a viewpoint;
- identifying objects in the digital image based at least upon an analysis of the cluster map and the digital image;
- and
- storing an indication of the identified objects in a processor-accessible memory system.
A method for detecting objects and background in a digital image, and the method implemented at least in part by a data processing system and comprising the steps of:
- receiving the digital image representing a scene;
- identifying range information associated with the digital image, the range information including distances of pixels in the scene from a known reference location;
- generating a plurality of cluster groups based at least upon an analysis of the range information and the digital image, the cluster groups representing groupings of pixels in the digital image according to their distances from a viewpoint;
- identifying objects in the digital image based at least upon an analysis of the cluster groups and the digital image;
- and
- storing an indication of the identified objects in a processor-accessible memory system.
A system for detecting objects in a digital image comprising:
- a data processing system;
- and
- a memory system communicatively connected to the data processing system, the memory system storing instructions configured to cause the data processing system to implement a method for detecting objects in a digital image, wherein the instructions comprise:
- receiving the digital image representing a scene;
- identifying range information associated with the digital image, the range information including distances of pixels in the scene from a known reference location;
- generating a cluster map based at least upon an analysis of the range information and the digital image, the cluster map grouping pixels of the digital image by their distances from a viewpoint;
- and
- identifying objects in the digital image based at least upon an analysis of the cluster map and the digital image.
