Method and equipment for detecting fingers in images

Abstract

The invention provides a method and equipment for detecting fingers in images. The method includes: extracting a candidate finger-palm center axis traversing candidate fingers and a candidate palm from a binary image generated from an image; generating shape features of the candidate fingers and the candidate palm corresponding to the candidate finger-palm center axis; and judging whether the candidate finger-palm center axis stems from a human hand or not according to shape features of fingers and a palm of a human. By the method and the equipment for detecting the fingers in the images, the features with notable physical meanings are extracted from the images, and the fingers are detected by the aid of the extracted features, so that the fingers are detected accurately and efficiently.

Description

technical field

[0001] The present invention relates to an image processing method and device, and more particularly to a method and device for detecting fingers in an image, and a method and device for gesture recognition in an image. Background technique

[0002] At present, in the field of vision-based human-computer interaction, a variety of gesture recognition methods have been proposed, and most of these gesture recognition methods are based on finger detection. However, most of the existing finger detection methods tend to perform finger detection in a small local area (e.g., fingertip area), and the detected features often do not have clear physical characteristics, e.g., root point, palm point Important human hand shape information is ignored in the detection process.

[0003] In Patent Document 1 (JP2008152622A), a method for interacting with fingers is provided, in which: firstly, after geometric color correction, the frame difference method is used to obtain the...
