Abstract
A method and an apparatus localize an object part location in a digital image. The method according to one embodiment accesses digital image data containing an object part; obtains an initial position estimate for object part location of the object part; extracts a sub-image window around the initial position estimate of the object part location; calculates feature values based on pixel values within the sub-image window; and determines an updated position estimate for the object part location based on the calculated feature values.
Claims20
A method of localizing an object part in a digital image, said method comprising:
- accessing digital image data containing an object part;
- obtaining an initial position estimate for object part location of said object part;
- extracting a sub-image window around said initial position estimate of said object part location;
- calculating feature values based on pixel values within said sub-image window;
- and
- determining an updated position estimate for said object part location based on said calculated feature values.
An apparatus for localizing an object part in a digital image, said apparatus comprising:
- an image data unit for providing digital image data containing an object part;
- a sub-image analysis unit for extracting object part sub-images from said digital image data, said sub-image analysis unit extracting object part sub-images by
- obtaining an initial position estimate for an object part location of said object part, and
- extracting a sub-image window around said initial position estimate of said object part location;
- and
- a feature values analysis unit for estimating object part location, said feature values analysis unit estimating object part location by
- calculating feature values based on pixel values within said sub-image window;
- and
- determining an updated position estimate for said object part location based on said calculated feature values.
