Detecting pedestrians using patterns of motion and appearance in videos
First Claim
Patent Images
1. A method for detecting a moving object in a temporal sequence of images of a video, comprising:
- selecting images from the temporally ordered sequence of images;
applying a set of functions to the selected images to generate a set of combined images;
evaluating a linear combination of filters on a detection window in the set of combined images to determine motion and appearance features of the detection window, in which the filters are two-dimensional;
summing the motion and appearance features to determine a cumulative score; and
classifying the detection window as including the moving object when the cumulative score is greater than a predetermined threshold.

Abstract
A method detects a moving object in a temporal sequence of images. Images are selected from the temporally ordered sequence of images. A set of functions is applied to the selected images to generate a set of combined images. A linear combination of filters is applied to a detection window in the set of combined images to determine motion and appearance features of the detection window. The motion and appearance features are summed to determine a cumulative score, which enables a classification of the detection window as including the moving object.
