Abstract
The disclosure relates to a device and a method in the device for recognizing a 3D gesture. The device is connected to a sensor and has access to a database of gesture images including indexable features of normalized gesture images. The indexable features include a position and an orientation for each pixel of edge images of the normalized gesture images. The method includes capturing (110) an image of the 3D gesture via the sensor, normalizing (120) the captured image, deriving (130) indexable features from the normalized captured image, and comparing (140) the derived indexable features with the indexable features of the database using a similarity function. The method also includes determining (150) a gesture image in the database matching the 3D gesture based on the comparison.

19. A method for recognizing a three dimensional, 3D, gesture, the method being performed in a device (20) having access to a database (52) of gesture images, the device communicating with a sensor (34) adapted to capture an image (33) of the 3D gesture, wherein the database (52) of gesture images comprises indexable features (54) of normalized gesture images, the indexable features comprising a position and an orientation for each pixel of edge images of the normalized gesture images, the method comprising:
-
capturing (110) the image (33) of the 3D gesture via the sensor, normalizing (120) the captured image in accordance with the normalized gesture images of the database (52) to allow for a comparison, deriving (130) indexable features (36) from the normalized captured image (33), the indexable features (36) comprising a position and an orientation for each pixel of an edge image of the normalized captured image, comparing (140) the derived indexable features (36) with the indexable features (54) of the database using a similarity function, and determining (150) a gesture image in the database (52) matching the 3D gesture based on the comparison;
wherein each entry in the database (52) of gesture images is tagged with associated 3D motion parameters comprising three orientation and three position parameters, the method further comprising;retrieving 3D motion parameters associated with the determined gesture image matching the 3D gesture from the database (52). - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 35, 36)
