Transformation Invariance in Hand Shape Recognition [PDF]

18th International Conference on Pattern Recognition (ICPR'06), 2006
In hand shape recognition, transformation invariance is key for successful recognition. We propose a system that is invariant to small scale, translation and shape variations. This is achieved by using a-priori knowledge to create a transformation subspace for each hand shape.

Shape registration in the time of transformers

CoRR, 2021
In this paper, we propose a transformer-based procedure for the efficient registration of non-rigid 3D point clouds. The proposed approach is data-driven and adopts for the first time the transformer architecture in the registration task. Our method is general and applies to different settings.

Shape Transformation of Polymer Vesicles. [PDF]

Acc Mater Res
Life activities, such as respiration, are accomplished through the continuous shape modulation of cells, tissues, and organs. Developing smart materials with shape-morphing capability is a pivotal step toward life-like systems and emerging technologies of wearable electronics, soft robotics, and biomimetic actuators.
