Embodiment Construction

[0033] According to an embodiment of the present invention, a gesture judgment method is provided, which is applied to an electronic device with a screen capture function. The gesture judgment method includes: obtaining corresponding angles / directions of a plurality of motion history images from a plurality of motion history images; judging whether a current gesture control is valid according to the angles / directions of the motion history images; and if it is valid, correct After weight adjustment is performed on the angle / direction of the motion history images, a judgment result of the current gesture control is obtained.

[0034] In order to have a better understanding of the above and other aspects of the present invention, the following specific embodiments are described in detail in conjunction with the accompanying drawings.

[0035] The technical terms in this specification refer to the idioms in the technical field. If this specification describes or defines some terms, the...

Abstract

A gesture judgment method used in an electronic device having frame capturing function is provided. A plurality of MHI (motion history image) angles / directions are obtained from a plurality of corresponding MHIs. Whether a current gesture control is valid is judged according to the MHI angles / directions. If the current gesture control is valid, then weight assignment is performed on the MHI angles / directions to obtain a judgment result of the current gesture control.

Description

Technical field [0001] The present invention relates to a gesture judgment method applied to an electronic device, and more particularly to a method for judging a gesture using a motion history image (MHI). Background technique [0002] Currently, a variety of technologies that can recognize human behavior have been proposed. Motion History Image (MHI) is one of the technologies for identifying human behavior. The basic concept of MHI is to identify "moving objects" based on the differences between consecutive moving images. The basic principle of MHI is to perform (1) mutual exclusion (XOR) or (2) absolute value subtraction of all bitmaps of two images before and after to find the difference between the two images. If the camera is not moving, the difference found should be the image of the moving object. [0003] For accuracy, delete some unqualified image blocks. such as: [0004] (1) From the perspective of subtracting absolute values, if the value after subtracting the abso...
