- Abstract
- With the great success in neural radiance fields (NeRF), human-specific NeRF has been actively introduced in recent years. However, such human rendering techniques often have difficulties to recover subtle details of textural surfaces such as wrinkles on clothes, which are mostly generated by complicated human motions. To solve this problem, we propose a new method for human-specific NeRF based on multi-scale and multi-view feature blending. Specifically, multi-scale image features, which are sampled from different views, are combined into the transformer architecture. This blended feature successfully guides the NeRF network to render photo-realistic results by enhancing local details of the human performer. Experimental results on the ZJU-MoCap dataset show that the proposed method outperforms previous methods both in qualitative and quantitative evaluations.
