Facial landmark detection is an essential module in many face related applications and it often appears as the most time consuming part in face processing pipeline. This paper proposes a fast and effective method for facial landmark detection using Haar cascade classifiers and a simple 3D head model, which not only detects the position of landmark points but also gives an estimation of head pose such...
This paper presents a general texture mapping framework for image-based 3D modeling. It aims to generating seamless texture map for 3D model created by real-world photos under uncontrolled environment. Our proposed method addresses two challenging problems: 1) texture discontinuity due to system error in 3D modeling from self-calibration; 2) color/lighting difference among images due to real-world...
Depth-map merging is one typical technique category for multi-view stereo (MVS) reconstruction. To guarantee accuracy, existing algorithms usually require either sub-pixel level stereo matching precision or continuous depth-map estimation. The merging of inaccurate depth-maps remains a challenging problem. This paper introduces a bundle optimization method for robust and accurate depth-map merging...
