Look up Table (LUT) Method for Image Halftoning
Recently we have applied Look Up Table (LUT) Method for inverse halftoning. We also proposed tree-structure LUT inverse halftoning in order to reduce memory requirements of the LUT method. In this paper we introduce LUT based halftoning method. Pixels from a causal neighborhood and the contone value of the current pixel will be included in the LUT. The LUT halftoning will require no arithmetic ...
متن کاملFilter Look Up Table method for Power Amplifiers Linearization
— This paper presents a new method of digital adaptive predistortion for linearization of Power Amplifiers (PA) exhibiting memory effects. The predistorter (PD) device consists of a Look-Up-Table (LUT) gain followed by a codebook of filters addressed by the index of the LUT. The adaptation is derived from direct learning for the LUT gains and indirect learning for the filter coefficients. We co...
متن کاملLook-up table (LUT) method for inverse halftoning
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 the best methods known for inverse halftonin...
متن کاملLook up Table Based Low Power Analog Circuit Testing
In this paper, a method of low power analog testing is proposed. In spite of having Oscillation Based Built in Self-Test methodology (OBIST), a look up table based (LUT) low power testing approach has been proposed to find out the faulty circuit and also to sort out the particular fault location in the circuit. In this paper an operational amplifier, which is the basic building block in the ana...
متن کاملDirect Addressing Techniques of Table Look-up
Table look-up is the most time-consuming part of many SAS programs. Base SAS offers a rich collection of built-in searching techniques. Merging, SQL joins, formats, SAS indexes all serve the purpose of locating relevant data. For custom programming, SAS offers arrays, whose direct addressability lends itself to implementing just about any searching algorithm. Array-based lookup is not a ready-t...
