Problems solved by technology

The disadvantage of this method is that it relies on highly discriminative features (i.e., faces) taken from a specific perspective (i.e., frontal)

[0089] Figure 4 A method 400 is shown for identifying objects in a scene using a camera. The purpose of the method 400 is to determine a sequence 461 of camera settings to identify the object of interest 100 with a minimum number of observations. As an example, reference is used to capture such as Figure 1B Shown is an image 120 of a scene containing a candidate object 130 to determine whether the candidate object is Figure 1A The method 400 is illustrated with the PTZ camera 140 of the object 100 of interest shown. An object of interest is described by a predetermined plurality of attributes determined using the method described below. Method 400 does not make any a priori assumptions about candidate objects 130 other than that candidate objects 130 share the same type of attributes as object of interest 100 . For example, in one VIDD configuration, the candidate object 130 and the object of interest 100 are both pedes...

Abstract

The invention provides a system and a method for object re-identification. The method (400) of identifying, with a camera, an object in an image (120) of a scene, includes the steps of determining (410) a distinctiveness (411) of each of a plurality of attributes of an object of interest (100), independent of a camera viewpoint; determining (820) a detectability (821) of each of the plurality of attributes based on a relative orientation (541) of a candidate object (130) in the image (120) of the scene; determining (460) a camera setting (461) for viewing the candidate object (130) based on the determined distinctiveness (411) of at least one attribute, so as to increase the detectability of the at least one attribute; and capturing (420) an image of the candidate object with the determined camera setting (461) to determine (440) a confidence (441) that the candidate object is the object of interest.

Description

technical field [0001] The present invention relates generally to image processing, and more particularly to a method, system and apparatus for planning a sequence of camera settings, such as pan, tilt and zoom values, for determining whether a candidate object is an object of interest. In one example, the terms "candidate subject" and "subject of interest" refer to (i) a person in a crowded airport, where the person is only one person in the crowd, and (ii) a person in the crowd identified as a special followig. The present invention also relates to a computer program product comprising a computer readable medium on which is recorded a computer program record for planning a series of camera settings for determining whether a candidate object is an object of interest. Background technique [0002] Public spaces such as shopping malls, car parks and train stations are increasingly being monitored using massive networks of video cameras. Application areas for mass video surv...
