Look-up table (LUT) method for inverse halftoning
IEEE Transactions on Image Processing, 2001 In this paper we propose look-up table (LUT) based methods for inverse halftoning of images. The LUT for inverse halftoning is obtained from the histogram gathered from a few sample halftone images and corresponding original images. The method is extremely fast (no filtering is required) and the PSNR and visual image quality achieved is comparable to ...

Behavioral Modeling of Microwave Power Amplifiers Using A Look Up Table Method [PDF]
2007 Asia-Pacific Microwave Conference, 2007 The possibility of building a microwave power amplifier (PA) behavioral model based on the look-up table principle is investigated. The model so constructed avoids the difficulties in model structure selection and/or its parameter estimation.

Look up table (LUT) method for image halftoning
Proceedings 2000 International Conference on Image Processing (Cat. No.00CH37101), 2002We have previously applied the look up table (LUT) method for inverse halftoning. We also proposed a tree-structure LUT inverse halftoning in order to reduce the memory requirements of the LUT method. We introduce the LUT based halftoning method. Pixels from a causal neighborhood and the contone value of the current pixel are included in the LUT.

Improved look-up table method of computer-generated holograms
Applied Optics, 2016Heavy computation load and vast memory requirements are major bottlenecks of computer-generated holograms (CGHs), which are promising and challenging in three-dimensional displays. To solve these problems, an improved look-up table (LUT) method suitable for arbitrarily sampled object points is proposed and implemented on a graphics processing unit (GPU)

Look Up Table Method for Five Hole Probe Data Reduction
Journal of Aerospace Sciences and Technologies, 2023A lookup method for extracting flow field information from five hole probe measurements is presented. The look up table method consists of two step interpolation. In the first step, the calibration space is divided into a large number of small intervals of yaw and pitch coefficients (0.1, 0.05 or 0.01) and the required quantities are interpolated using

Phase-searching look-up table method for computer-generated holograms
Journal of Electronic Imaging, 2014A phase-searching look-up table (PS-LUT) method is proposed to dramatically reduce the memory size of the new look-up table (N-LUT) method as well as to keep its advantage of fast computational speed. Small quantities of samples are chosen as the basic phase points (BPPs) in the principle fringe pattern (PFP), and phases of the object points for BPPs ...

Novel de-embedding method with look-up table for characterization of interconnects
2016 IEEE Electrical Design of Advanced Packaging and Systems (EDAPS), 2015A new de-embedding technique is introduced in this paper with pre-established Look-Up Table (LUT) for accurate characterization of high speed interconnects, particularly for printed circuit board (PCB). The method de-embeds the test fixture effects from the measurement or/and simulation results.

Fast classification algorithm using table-look-up method
Journal of Electronics (China), 1986In this paper, a fast classification algorithm which uses a table-look-up method is proposed. Both theoretical and experimental results are shown: (1) in two dimensional case the computation time can be reduced to the same order of time needed for the data I/O; (2) in the case of more than two dimensions more than half a computation time can be saved ...
