PCA-Based 3D Face Photography
This paper presents a 3D face photography system based on a small set of training facial range images. The training set is composed by 2D texture and 3D range images (i.e. geometr...

The Projective Linear Transition Map for Constructing Smooth Surfaces
Abstract—We exhibit the essentially unique projective linear (rational linear) reparameterization for constructing Cs surfaces of genus g > 0. Conversely, for quadrilaterals a...

Fast and correspondence-less camera motion estimation based on voting mechanism and morton codes
This paper proposes a computationally efficient approach for estimating camera motion based on a voting mechanism that neither relies on explicit feature matching nor RANSAC. In t...

Content-based image retrieval by clustering
In a typical content-based image retrieval (CBIR) system, query results are a set of images sorted by feature similarities with respect to the query. However, images with high fea...
