Multiscale Shape and Detail Enhancement from Multi-light Image Collections
image enhancement NPR relighting shape depiction bilateral filter multiscale image processing
2016/5/24
We present a new image-based technique for enhancing the shape
and surface details of an object. The input to our system is a small
set of photographs taken from a fixed viewpoint, but under varying...
An Implicit Geometric Regularization of 3D Building Shape Using Airborne LIDAR Data
LIDAR Building Edge Incremental Generalization Reconstruction
2015/12/4
The prime objective of this paper is to develop a new method for regularizing noisy building outlines extracted from airborne LiDAR data. For the last few decades, a lot of research efforts have been ...
This article describes a new method of Shape from Shading, Shape from Isophotes. Shape from Isophotes uses the image isophotes
for recovering the object surface normals. It is a propagation method. ...
