About caffe layers:
-
deep_hand_model_calc_norm_scale_layer
calculates normalized hand scale ("s" in raw paper)
-
deep_hand_model_solve_global_hand_scale_layer
predicts global hand scale during inference
-
deep_hand_model_solve_scale_normalized_global_location_layer
recovers scale normalized global joints from scale normalized root-relative 3d joints (just by adding wrist location)
-
deep_hand_model_solve_scale_normalized_global_z_root_layer
predicts global depth (z) of root: wrist joint
