In this paper, we introduce NeuralHDHair, a flexible, fully automatic system for modeling high-fidelity hair from a single image. ...
To improve the efficiency of a traditional hair growth algorithm, we adopt a local neural implicit function to grow strands based on the estimated 3D hair geometric features. ...
Conclusion and Future Work In this paper, we introduced an automatic learning-based monocular hair modeling system NeuralHDHair to produce a high-fidelity hair-strand model as shown in Fig. 9 (Please ...

Therefore we propose a more complex model by introducing a 2D mesh-based motion compensation technique, also known as image warping, to compensate the global motion. ...
Global Motion Compensation is one of the key technologies for aerial image processing e.g. to detect moving objects on the ground or to generate a mosaick image of the observed area. ...
In our approach we assume a planar surface in each of the small patches which can therefore be modeled by an affine transform. ...
