Motion compensated shape error concealment

2004 International Conference on Image Processing, 2004. ICIP '04., 2005
The introduction of Video Objects (VOs) is one of the innovations of MPEG-4. The alpha-plane of a VO defines its shape at a given instance in time and hence determines the boundary of its texture. In packet-based networks, shape, motion, and texture are subject to loss.

Perfect error compensation via algorithmic error cancellation

2016 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2016
This paper presents a novel statistical error compensation (SEC) technique — algorithmic error cancellation (AEC)-for designing robust and energy-efficient signal processing and machine learning kernels on scaled process technologies. AEC exhibits a perfect error compensation (PEC) property, i.e., it is able to achieve a post-compensation error rate ...

Quantisation-error compensation techniques

Proceedings of the Institution of Electrical Engineers, 1969
If a digital computer is operated as an online computational device, amplitude-quantisation errors are incurred when analogue data is fed into the machine. This analogue-digital conversion operation introduces a fundamental accuracy limitation into a control or measurement system which incorporates an online digital computer. The paper investigates the

Optimal control design using error compensation

Guidance, Navigation, and Control Conference, 1995
A technique is presented which enables the o p timal control designer to compensate for the approximations usually made to obtain an analytical optimal control. Instead of discarding the approximation terms, they are treated as bounded controls (called error compensation controls), and the bounds are replaced by penalty terms in the performance index ...

Computer-generated holograms with error compensation

Applied Optics, 1988
We analyze computer-generated holograms (CGH) of Lohmann types I and III and discuss their overall errors employing the following modifications, listed in order of increasing importance: phase-only correction (Ptype), virtual increase of the cell number, optimized use of the available plotting area, expansion of the amplitude dynamic range (D-type ...

Error Compensation Strategy for Parallel Error Diffusion

2015 8th International Symposium on Computational Intelligence and Design (ISCID), 2015
Parallelizing error diffusion is a difficult task because of its inherently serial character in the original form. In this paper, we describe an error compensation strategy for parallel error diffusion. In our method, original image is split into independent blocks.

Geometrical error compensation of machines with significant random errors

ISA Transactions, 2005
In this paper, we present a new statistical approach towards soft geometrical error compensation of machines with significant errors. The approach, based on an analysis of the probability of the random error recurring, can reduce the adverse influence of random errors on the compensation of systematic errors.

Geometrical Error Compensation

2001
In automated positioning machines such as Co-ordinate Measuring Machines (CMM) and machine tools, the relative position errors between the end-effector of the machine and the workpiece directly affect the quality of the final product or the process of concern.

Robust, Error-Tolerant Photometric Projector Compensation

IEEE Transactions on Image Processing, 2015
We propose a novel error tolerant optimization approach to generate a high-quality photometric compensated projection. The application of a non-linear color mapping function does not require radiometric pre-calibration of cameras or projectors. This characteristic improves the compensation quality compared with related linear methods if this approach ...

Error compensation in reflection type centering error testing

Optical Review, 2009
The error compensation for an error caused from unwanted surfaces when using single autocollimator reflection type centering error testing. And compare the result with commercial equipment like OptiCentric built by TRIOPTICS GmbH using a concave lens and a convex lens.
