Energy Efficient Approximate 3D Image Reconstruction

An Efficient Approach to 3D Image Reconstruction

† MIS Department, Al Zaytoonah University of Jordan, Amman, Jordan †† Computer Science Department, Al Anbar University, Anbar, Iraq Summary The images can be visualized in three dimensional (3D) using standard techniques, these 3D techniques are used to enhance the view of images. Converting two dimensional (2D) images into 3D images is an important part of image application. An efficient appro...

Efficient Reconstruction Techniques for Post-Rendering 3D Image Warping

Image-based rendering replaces the difficult physical simulation problem of conventional computer graphics with a difficult reconstruction problem. In this paper, we introduce efficient methods for eliminating common reconstruction artifacts in 3D image warping. These methods are suitable for hardware implementation. We study the reconstruction problem in the context of the 3D warp’s applicatio...

Approximate Newton’s method for Tomographic Image Reconstruction

In this report we solved a regularized maximum likelihood (ML) image reconstruction problem (with Poisson noise). We considered the gradient descent method, exact Newton’s method, pre-conditioned conjugate gradient (CG) method, and an approximate Newton’s method, with which we can solve a million variable problem. However, the current version of approximate Newton’s method converges slow. We co...

Energy-Efficient Approximate Computation in Topaz

We present Topaz, a new task-based language for computations thatexecute on approximate computing platforms that may occasion-ally produce arbitrarily inaccurate results. The Topaz implementa-tion maps approximate tasks onto the approximate machine and in-tegrates the approximate results into the main computation, deploy-ing a novel outlier detection and reliable reexecution...
