Abstract
Disclosed is a method and apparatus for face detection using an adaptive threshold. The method includes determining a detection box in an input image, calculating a confidence score indicating whether an object in the detection box corresponds to a face, setting an adaptive threshold based on a size of the detection box, and determining whether the object in the detection box corresponds to a face based on comparing the confidence score to the adaptive threshold.
Claims26
A face detection method, comprising:
- determining a detection box in an input image;
- calculating a confidence score indicating whether an object in the detection box corresponds to a face;
- setting an adaptive threshold based on a size of the detection box and a quality of the input image;
- and
- determining whether the object in the detection box corresponds to a face based on comparing the confidence score to the adaptive threshold.
A face detection apparatus, comprising:
- a processor configured to:
- determine a detection box in an input image,
- calculate a confidence score indicating whether an object in the detection box corresponds to a face,
- set an adaptive threshold based on a size of the detection box and a quality of the input image, and
- determine whether the object in the detection box corresponds to a face based on comparing the confidence score to the adaptive threshold.
A face detection apparatus, comprising:
- a sensor configured to receive an image;
- and
- a processor configured to:
- determine a detection box in the image,
- calculate a confidence score indicating whether an object in the detection box corresponds to a face,
- determine that the object in the detection box corresponds to a face, in response to the confidence score being greater than a maximum threshold,
- set an adaptive threshold based on a size of the detection box and a quality of the input image, and
- determine whether the object in the detection box corresponds to a face based on comparison of the confidence score to the adaptive threshold, in response to the confidence score being lesser than the maximum threshold.
