Gesture identification with natural images
First Claim
Patent Images
1. A method for gesture identification independent of color temperature with natural images for adapting to indistinct images and gestures as fast swipes, comprising the steps of:
- A.) generating a time-based series of images;
B.) selecting successive images from the series of the images, and using the entire selected successive images to generate a plurality of variant images;
C.) extracting a plurality of image features from the variant images; and
D.) comparing a varying pattern of the image features with a gesture definition to identify a gesture;
wherein the method does not comprise the steps of;
recognizing a shape of the gesture in each selected image, and determining a position of the gesture in each selected image.

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 gesture identification independent of the color temperature with natural images for adapting to indistinct images and gestures as fast swipes, comprising the steps of:
-
A.) generating a time-based series of images; B.) comparing the entire series of the images to generate a plurality of differential images from the series of the images; and C.) comparing at least one of the differential images with a gesture definition to identify a gesture; wherein the method does not comprise the steps of; recognizing a shape of the gesture in each of the series of the images, and determining a position of the gesture in each of the series of the images. - View Dependent Claims (7, 8, 9, 10, 11)
