Abstract
Disclosed herein are systems, devices, and processes for gesture detection. A method includes capturing a series of images. The method includes generating motion isolation information based on the series of images. The method includes generating a composite image based on the motion isolation information. The method includes determining a gesture based on the composite image. The processes described herein may include the use of convolutional neural networks on a series of time-related images to perform gesture detection on embedded systems or devices.
Claims18
A method, comprising:
- receiving a series of captured images;
- generating motion isolation information based on the series of images;
- generating a composite image based on the motion isolation information, wherein generating the composite image includes applying a color gradient, wherein applying the color gradient includes determining a series of substantially evenly spaced color intervals based at least in part on the number of images in the series of images that are to be merged to generate the composite image, wherein applying the color gradient includes applying the darkest remaining color value or the lightest remaining color value of the series of substantially evenly spaced color intervals to the oldest remaining image of the series of images that are to be merged to generate the composite image;
- and
- determining a gesture based on the composite image.
A system comprising:
- an image sensor configured to capture a series of images;
- and
- a processor configured to generate motion isolation information based on the series of images,
- wherein the processor is further configured to generate a composite image based on the motion isolation information, wherein generating the composite image includes applying a color gradient, wherein applying the color gradient includes determining a series of substantially evenly spaced color intervals based at least in part on the number of images in the series of images that are to be merged to generate the composite image, wherein applying the color gradient includes applying the darkest remaining color value or the lightest remaining color value of the series of substantially evenly spaced color intervals to the oldest remaining image of the series of images that are to be merged to generate the composite image, and
- wherein the processor is further configured to determine a gesture based on the composite image.
