Abstract
An image processing apparatus 10 acquires an image. And, the image processing apparatus 10 extracts a domain characterizing an object of gesture recognition from the acquired image. Then, the image processing apparatus 10 maps domains between frames of the image. And then, the image processing apparatus 10 extracts a moving direction of the domains. And then, the image processing apparatus 10 outputs the moving direction when a moving distance of the domains is greater than a predetermined threshold. And then, the image processing apparatus 10 updates the threshold using a moving distance exceeding the threshold.
Claims7
An image processing apparatus comprising:
- an image acquiring unit that acquires an image;
- a domain extracting unit that extracts a domain characterizing an object of gesture recognition from the image acquired by the image acquiring unit;
- a mapping unit that maps domains extracted by the domain extracting unit between frames of the image;
- a direction extracting unit that extracts a moving direction of the domains mapped by the mapping unit;
- a direction output unit that outputs the moving direction extracted by the direction extracting unit when a moving distance of the domains mapped by the mapping unit is greater than a predetermined threshold;
- and
- a threshold updating unit that updates the threshold using a moving distance exceeding the threshold.
