Abstract
An optical flow accelerator includes a face recognizing unit to recognize a face from a stereo image provided the optical flow accelerator. A depth information calculation unit calculates depth information of the recognized face on a basis of the recognized face. A face tracking unit tracks a size and a shape of the face depending on a movement direction when the recognized face moves. A controller controls generates depth information of the recognized face depending on an optical flow.
Claims9
An optical flow accelerator, comprising:
- an image input unit configured to input a stereo image;
- a face recognizing unit configured to recognize a face from the stereo image;
- a depth information calculation unit configured to calculate depth information of the recognized face on a basis of the recognized face;
- a face tracking unit configured to track a size and a shape of the face depending on a movement direction when the recognized face moves;
- and
- a controller configured to control an operation of the face recognizing unit, the face tracking unit, and the depth information processing unit to generate depth information of the recognized face depending on an optical flow.
An optical flow acceleration method, the method comprising:
- inputting a stereo image;
- recognizing a face from the stereo image;
- calculating depth information of the recognized face on a basis of the recognized face;
- erasing a background having depth information different from the recognized face from the input image based on the depth information to generate a partial image;
- and
- analyzing a movement of the recognized face in the partial image to generate the depth information of the recognized face through an optical flow technique.
