Abstract
Described is a technique for optimization an image for facial detection. More specifically, described is a process of predicting the location of a face within an image and adjusting image settings based on at least a portion of the predicted location of the face. An image may be adjusted based on the characteristics of a metering region, which may be selected prior to performing facial detection. For example, the metering region may be a specified shape with dimensions equal to a certain percentage of the input image and placed at a specified location. The result of using such a metering region is that the image adjustments may be based on a portion of the face, and therefore, may be optimized for facial detection.
Claims19
A method comprising:
- receiving, by a computing device, a live image captured by a camera, wherein the live image continuously captures an image within a field of view of the camera;
- receiving, by the computing device, an indication to perform facial recognition on a frame of the live image;
- selecting, by the computing device, in response to the indication, a metering region within a portion of the frame prior to attempting to locate a position of a face within any portion of the frame, wherein the selected metering region is smaller in size than a first metering region, the first metering region configured as part of a default capture setting of the camera;
- adjusting, by the computing device, the frame based on the selected metering region;
- and
- detecting, by the computing device, the face within the adjusted frame.
A method comprising:
- receiving, by a computing device, an image captured by a camera;
- receiving, by the computing device, an indication to perform facial recognition on the image;
- selecting, by the computing device, in response to the indication, a metering region within a portion of the captured image based on a set of coordinates, wherein the metering region is selected prior to locating a position of a face within the image, wherein the selected metering region is smaller in size than a first metering region, the first metering region configured as part of a default capture setting of the camera;
- adjusting, by the computing device, the image based on the selected metering region;
- and
- detecting, by the computing device, the face within the adjusted image.
A method comprising:
- receiving, by a computing device, a live image captured by a camera, wherein the live image continuously captures an image within a field of view of the camera;
- receiving, by the computing device, an indication to perform facial recognition on a frame of the live image;
- during a facial detection step of the facial recognition, selecting, by the computing device, in response to the indication, a metering region within a portion of the frame prior to attempting to locate a position of a face within any portion of the frame, wherein the selected metering region is smaller in size than a first metering region, the first metering region configured as part of a default capture setting of the camera;
- adjusting, by the computing device, the frame based on the selected metering region;
- and
- detecting, by the computing device, the face within the adjusted frame.
