2D to 3D convertion based on edge defocus and segmentation
This paper presents a depth estimation method which converts two-dimensional images into three-dimensional data. Based on two-dimensional wavelet analysis of Lipschitz regularity ...

Evaluating the effectiveness of spatial memory in 2D and 3D physical and virtual environments
User interfaces can improve task performance by exploiting the powerful human capabilities for spatial cognition. This opportunity has been demonstrated by many prior experiments....

Classification of curves in 2D and 3D via affine integral signatures
We propose new robust classification algorithms for planar and spatial curves subjected to affine transformations. Our motivation comes from the problems in computer image recognit...

A suggestive interface for image guided 3D sketching
We present an image guided pen-based suggestive interface for sketching 3D wireframe models. Rather than starting from a blank canvas, existing 2D images of similar objects serve ...

Face poser: interactive modeling of 3D facial expressions using model priors
In this paper, we present an intuitive interface for interactively posing 3D facial expressions. The user can create and edit facial expressions by drawing freeform strokes, or by...
