Abstract
Abstract Automatic vision system object indexing and image database query system using both path-dependent and path-independent features of moving objects within a sequence of images. Feature vectors of both average over frames of an object traversing the field of view plus average over blocks of a grid for a path association. Color histograms may be an included feature.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
84 words
A method of searching for a video object in a video sequence of images, comprising: (a) providing a database of feature vectors of video objects; (b) providing a target feature vector; (c) comparing said target feature vector to each feature vector of said database; (d) ranking said feature vectors of said database according to the results of step (c); and (e) finding video objects by an association of video objects with said feature vectors of said database together with the results of step (d).
Claim 2
Independent Claim
84 words
A method of searching for a video object in a video sequence of images, comprising: (a) providing a database of feature vectors of video objects; (b) providing a target feature vector; (c) comparing said target feature vector to each feature vector of said database; (d) ranking said feature vectors of said database according to the results of step (c); and (e) finding video objects by an association of video objects with said feature vectors of said database together with the results of step (d).
Claim 3
Dependent Claim
29 words
The method of claim 1 , wherein: (a) said feature vectors of said database include both path-dependent and path-independent features extracted from video objects moving in sequences of images.
Claim 4
Dependent Claim
47 words
The method of claim 2 , wherein: (a) said path-dependent features for a video object include a sequence of grid blocks traversed by said video object together with averages of features extracted from said video object when said video object was located in a corresponding grid block.
