Compression of images in CFA format
(IEEE, 2006)In this paper, images in Color Filter Array (CFA) format are compressed without converting them to full-RGB color images. Green pixels are extracted from the CFA image data and placed in a rectangular array, and compressed ... -
Idler-efficiency-enhanced long-wave infrared beam generation using aperiodic orientation-patterned GaAs gratings
(Optical Society of America, 2016)In this paper, we design aperiodic gratings based on orientation-patterned gallium arsenide (OP-GaAs) for converting 2.1 μm pump laser radiation into long-wave infrared (8-12 μm) in an idler-efficiency-enhanced scheme. ... -
JPEG hardware accelerator design for FPGA
(IEEE, 2007)A fully pipelined JPEG hardware accelerator that runs on FPGA is presented. The accelerator is designed interactively in a simulation environment, using a DSP hardware design automation tool chain. The encoder part of the ... -
Teager energy based feature parameters for robust speech recognition in car noise
(IEEE, Piscataway, NJ, United States, 1999)In this paper, a new set of speech feature parameters based on multirate signal processing and the Teager Energy Operator is developed. The speech signal is first divided into nonuniform subbands in mel-scale using a ... -
Teager energy based feature parameters for speech recognition in car noise
(Institute of Electrical and Electronics Engineers, 1999-10)In this letter, a new set of speech feature parameters based on multirate signal processing and the Teager energy operator is introduced. The speech signal is first divided into nonuniform subbands in mel-scale using a ...
