Sketch-based Normal Map Generation with Geometric Sampling

Yi He, Haoran Xie, Chao Zhang +2

Normal map is an important and efficient way to represent complex 3D models. A designer may benefit from the auto-generation of high quality and accurate normal maps from freehand…

Deep Patch-based Human Segmentation

Dongbo Zhang, Zheng Fang, Xuequan Lu +4

3D human segmentation has seen noticeable progress in re-cent years. It, however, still remains a challenge to date. In this paper, weintroduce a deep patch-based method for 3D hum…

G2MF-WA: Geometric Multi-Model Fitting with Weakly Annotated Data

Chao Zhang, Xuequan Lu, Katsuya Hotta +1

In this paper we attempt to address the problem of geometric multi-model fitting with resorting to a few weakly annotated (WA) data points, which has been sparsely studied so far.…

Blur-Countering Keypoint Detection via Eigenvalue Asymmetry

Chao Zhang, Xuequan Lu, Takuya Akashi

Well-known corner or local extrema feature based detectors such as FAST and DoG have achieved noticeable successes. However, detecting keypoints in the presence of blur has remaine…
