Abstract
A gesture recognition method includes performing a binarization process on an image to obtain a binarized image, wherein the binarized image includes a plurality of foreground pixels and a plurality of background pixels; determining whether the plurality of foreground pixels surrounds at least a first background pixel; and determining a gesture complying with a predefined gesture in response to determination that the plurality of foreground pixels surrounds the at least a first background pixel.
Claims24
A gesture recognition method, applied in a gesture recognition module, configured to determine a gesture to operate an electronic device correspondingly, the gesture recognition method comprising:
- providing an image capturing device, wherein the image capturing device is configured to sense the gesture to generate an image;
- performing a binarization process on the image, to obtain a binarized image, wherein the binarized image comprises a plurality of foreground pixels and a plurality of background pixels, the plurality of foreground pixels is corresponding to a foreground pixel value, and the plurality of background pixels is corresponding to a background pixel value;
- determining whether the plurality of foreground pixels within the binarized image surrounds at least a first background pixel, wherein the first background pixel is one background pixel of the plurality of background pixels;
- and
- determining the gesture complying with a predefined gesture in response to determination that the plurality of foreground pixels surrounds the at least a first background pixel, to operate the electronic device correspondingly.
A gesture recognition module, configured to operate an electronic device, comprising:
- an image capturing device, configured to sense a gesture and generate an image;
