Image processing system

An image processing system configured to receive a first stream of images at a first resolution from a first image source (12) with a field of view of an environment and a second stream of images (16) at a second resolution lower than said first resolution from a second image source (14) with substantially the same field of view as said first image source, said system comprising:

• a localizer (18) component configured to provide a location (20) for any object of interest independently of class within successive images of said second stream of images;
• a classifier (26) configured to:
• receive one or more locations selectively provided by said localizer, identify a corresponding portion of an image (17-N) acquired from said first stream at substantially the same time at which an image from said second stream in which an object of interest was identified and return a classification for the type of object within said identified portion of said image from said first stream;
• and
• a tracker (22) configured to associate said classification with said location through acquisition of successive images in said second stream.
