Abstract

A system (102) to generate a hand pose and includes a map-generating module that generates a hand map (300) a plurality of key points (302) from an input image of a hand. The system (102) also includes an identification module (210) that identifies an offset key point (314, kp1) out of the plurality of key points (302) located outside the hand map (300) and identify a reference key point (316, kp2) located inside the hand map (300) closest to the offset key point (314, kp1). In addition, the system (102) includes a modification module (214) that rotates the offset key point (314, kp1) to a new position at an intersection of the path of the rotation and the hand map (300). Finally, the system (102) includes a hand-pose generation module (216) that generates the hand pose subsequent to the shifting.

Dependent claims

A method for generating a hand pose, the method comprising:

generating (502), from an input image of a hand, a hand map (300) and a plurality of key points (302) of the hand;
identifying (504) at least one offset key point (314, kp1) from the plurality of key points (302) that are located outside the hand map (300);
identifying (506) a reference key point (316, kp2) located inside the hand map (300) and is semantically closest to the at least one offset key point;
rotating (508) the at least one offset key point (314, kp1) along a path of rotation with the reference key point (316, kp2) as a center;
shifting (510) the offset key point (314, kp1) to a new position at an intersection of the path of the rotation and the hand map (300);
and
generating (512) the hand pose subsequent to shifting of the offset key point (314, kp1) to the new position within the intersection.
