Method for determining the position of an object in an image, for determining an attitude of a persons face and method for controlling an input device based on the detection of attitude or eye gaze

摘要

The invention relates to a method for determining the position of an object in an image comprising the steps of: a)determining a first apparent position of the object in an image using a first detection method, b) determining a second apparent position of the object in an image using a second detection method and c) determining the difference between the first and second apparent position, and finally deciding that the real position is based on the first apparent position in case the difference is less than a predetermined difference value and deciding that the real position is based on the second apparent position in case the difference is larger than the predetermined difference value. Furthermore the invention relates to a method of determining an eye gaze direction and corresponding eye gaze detecting device, wherein, based on the determination of additional characteristic facial points in addition to the positioning of the eyes, in particular the irises, the eye gaze direction can be determined with only one image taken from only one camera. The invention also relates to an input device based on the detection of moving direction sequences.
