Gesture identification with natural images
First Claim
Patent Images
1. A method for identifying a gesture using natural images, wherein the method is independent of color temperature and adaptive to indistinct images caused by fast motion of an object, comprising the steps of:
- selecting a plurality of successive images from a series of the images frames, wherein for each of the selected plurality of successive images, entire image frames are used to generate a plurality of variant images; and
comparing a varying pattern of the variant images with a gesture definition to identify the gesture;
wherein the method does not comprise the steps of;
recognizing a shape of a gesture in each of the selected plurality of successive images, anddetermining a position of the gesture in each of the selected plurality of successive images.

Abstract
A method for gesture identification with natural images includes generating a series of variant images by using each two or more successive ones of the natural images, extracting an image feature from each of the variant images, and comparing the varying pattern of the image feature with a gesture definition to identify a gesture. The method is inherently insensitive to indistinctness of images, and supports the motion estimation in axes X, Y, and Z without requiring the detected object to maintain a fixed gesture.

6. A method for identifying a gesture using natural images, wherein the method is independent of color temperature and adaptive to indistinct images caused by fast motion of an object, comprising the steps of:
-
comparing the entire image frames of each of a plurality of successive images to generate a plurality of differential images from the series of the images; and comparing at least one of the differential images with a gesture definition to identify the gesture; wherein the method does not comprise the steps of; recognizing a shape of a gesture in each of the plurality of successive images, and determining a position of the gesture in each of the plurality of successive images. - View Dependent Claims (7, 8, 9, 10)
