Abstract
An image processing device includes a difference image generation unit which generates a difference image by obtaining a difference between frames of a cutout image which is obtained by cutting out a predetermined region on a photographed image; a feature amount extracting unit which extracts a feature amount from the difference image; and a recognition unit which recognizes a specific movement of an object on the photographed image based on the feature amount which is obtained from the plurality of difference images which are aligned in time sequence.
Claims13
An image processing device comprising:
- a region setting unit configured to detect a part of a body or a body as a target for being recognized from a photographed image which is aligned in time sequence and set a recognition region based on the detected part of the body or the body;
- a processing unit configured to track the recognition region in the photographed image set by the region setting unit;
- a feature amount extracting unit configured to extract a feature amount from the tracked recognition region in the photographed image;
- a recognition unit configured to recognize a specific movement of the part of the body or the body based on the feature amount extracted at the feature amount extracting unit;
- and
- a display control unit configured to control a display of a frame denoting the recognition region set by the region setting unit.
An image processing method comprising:
- detecting a part of a body or a body as a target for being recognized from a photographed image which is aligned in time sequence and setting a recognition region based on the detected part of the body or the body;
- tracking the set recognition region in the photographed image;
- extracting a feature amount from the tracked recognition region in the photographed image;
- recognizing a specific movement of the part of the body or the body based on the extracted feature amount extracted;
- and
- controlling a display of a frame denoting the set recognition region.
A non-transitory computer readable medium having stored thereon, a set of computer-executable instructions, for causing the computer to execute steps comprising:
- detecting a part of a body or a body as a target for being recognized from a photographed image which is aligned in time sequence and setting a recognition region based on the detected part of the body or the body;
- tracking the set recognition region in the photographed image;
- extracting a feature amount from the tracked recognition region in the photographed image;
- recognizing a specific movement of the part of the body or the body based on the extracted feature amount;
- and
- controlling a display of a frame denoting the set recognition region.
