Face detection and tracking |
| 摘要 |
Methods and systems for face detection and tracking using an image-based capture device are disclosed herein. The method includes generating a depth image of a scene, generating a mask image from the depth image, and detecting a position of a face of a user in the scene using the mask image. The method also includes determining an intensity of the face using a first color channel of the mask image and adjusting a gain level of a first color channel of the image-based capture device directed at the scene to achieve a target intensity of the face. |

1. A method for face detection and tracking using an image-based capture device, comprising:
generating a depth image of a scene; generating a mask image from the depth image; detecting a position of a face of a user in the scene using the mask image; determining an intensity of the face using a first color channel of the mask image by undoing a gamma correction of the mask image and averaging a mean intensity and a median intensity of the face within the mask image; and adjusting a gain level of the first color channel of the image-based capture device directed at the scene to achieve a target intensity of the face. |
