Threedimensional object recognition from single twodimensional images
 Artificial Intelligence
, 1987
"... A computer vision system has been implemented that can recognize threedimensional objects from unknown viewpoints in single grayscale images. Unlike most other approaches, the recognition is accomplished without any attempt to reconstruct depth information bottomup from the visual input. Instead, ..."

, three other mechanisms are used that can bridge the gap between the twodimensional image and knowledge of threedimensional objects. First, a process of perceptual organization is used to form groupings and structures in the image that are likely to be invariant over a wide range of viewpoints. Second
Stochastic Sampling of Two�dimensional Images
"... Stochastic sampling is a special anti�aliasing technique that originated in signal theory exam� ining functions of one variable �time�. However � in computer graphics two�dimensional images are sampled instead of one dimensional signals � thus the original results must be extended to two�dimensional ..."

Twodimensional imaging of a helicon discharge
, 1997
"... Abstract. Twodimensional images of the ionized argon light of a helicon discharge are made both along and across the magnetic field with various antenna configurations. Two antennas, a Nagoya type III and a helical antenna, are used to create a magnetized RF plasma with density in the range n ≤ 5 × ..."

Improved Cubic Convolution for Two Dimensional Image Reconstruction
"... This paper describes improved piecewise cubic convolution for twodimensional image reconstruction. Piecewise cubic convolution is one of the most popular methods for image reconstruction, but the traditional approach uses a separable twodimensional convolution kernel that is based on a onedimensio ..."

threedimensional over twodimensional imaging
, 2014
"... Aims Complex aortic atherosclerotic plaques (AAPs) carry a significant risk of embolism. Currently, twodimensional (2D) transoesophageal echocardiography (TOE) is the principal diagnostic tool of AAPs. However, we hypothesized that the data obtained from threedimensional (3D) imaging may improve A ..."

Interpolation of One and TwoDimensional Images with Pixelwise Photon Number Conservation
, 2000
"... The interpolation of one and twodimensional images is considered. The usual linear or cubic spline interpolations try to connect given data points. On the other hand, image data give area integrals of the radiation intensity (i.e., photon counts) over pixels. Based on variational principles, we ha ..."
