The com parameter in cropArea3D function #7

Closed LuciaXu closed 6 years ago

Hi, @moberweger Thank you for sharing your great work. I'm a little confused about the com parameter in cropArea3D function. If I'm not mistaken, it is the center of mass, around which the cube is cropped. But in loadSequence function of Importer (1017 line), the center joint position is passed as the com parameter. It seems a bit difference with what you've done in the paper, which use the center of mass of depth to segment hand. Since I'd like to follow what you've done in the paper, should I do the cropping like this: com,size=hd.detect(size=config['cube']) dpt, M, com = hd.cropArea3D(com=com, size=config['cube'])

Hi, The com parameter is the center of the hand (metacarpophalangeal joint). The center joint position as you mention is passed for debug purpose. What you have to do to follow the pipeline of the paper is to pass refineNet to the constructor of the Importer, and then pass docom=True to the loadSequence function.

docom=True calculates the center of mass, and the refineNet parameter (string with path to saved refinement network) calculates the refined location of the hand.
