Abstract
A gesture recognition apparatus including a detector, a controller and a gesture recognizer, and is able to detect a portion to be detected using an image captured at a first resolution without reducing the number of images to be entered per unit of time to an object detector by detecting an auxiliary portion instead when the portion to be detected is not detected at a second resolution, estimating the position of the auxiliary portion based on the position of the auxiliary portion, and extracting the periphery thereof from the image captured at the first resolution.
Claims13
A gesture recognition apparatus comprising:
- a first detector configured to detect a detection area including a portion of a body of an operator in a first image of a motion image captured at a first resolution;
- a second detector configured to detect an auxiliary area including an auxiliary portion used for detecting the portion in a second image of the motion image captured at the first resolution when the detection area cannot be detected;
- a controller configured to control, when the auxiliary area is detected, to cause a capturing unit to capture a third image of the motion image captured at a second resolution higher than the first resolution;
- a third detector configured to detect the detection area in the third image based on a predetermined positional relationship between the detection area and the auxiliary area;
- and
- a gesture recognizer configured to recognize a gesture of the portion based on an entire area of the first image or the detection area of the third image.
A method of recognizing gestures comprising:
- detecting a detection area including a portion of a body of an operator in a first image of a motion image captured at a first resolution;
- detecting an auxiliary area including an auxiliary portion used for detecting the portion in a second image of the motion image captured at the first resolution when the detection area cannot be detected;
- controlling, when the auxiliary area is detected, to cause a capturing unit to capture a third image of the motion image captured at a second resolution higher than the first resolution;
- detecting the detection area in the third image based on a predetermined positional relationship between the detection area and the auxiliary area;
- and
- recognizing a gesture of the portion based on an entire area of the first image or the detection area of the third image.
A program stored in a computer readable medium, the program comprising instructions of:
- detecting a detection area including a portion of a body of an operator in a first image of a motion image captured at a first resolution;
- detecting an auxiliary area including an auxiliary portion used for detecting the portion in a second image of the motion image captured at the first resolution when the detection area cannot be detected;
- controlling, when the auxiliary area is detected, to cause a capturing unit captured a third image of the motion image captured at a second resolution higher than the first resolution;
- detecting the detection area in the third image based on a predetermined positional relationship between the detection area and the auxiliary area;
- and
- recognizing a gesture of the portion based on an entire area of the first image or the detection area of the third image.
