1. 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.
