Direct Method of Decoding Multiple Images
Applied Optics, 1973In certain applications, especially x-ray and gamma-ray photography, pinhole cameras provide one of the only methods of producing sharp images. To increase the image quality, the use of an array of multiple pinholes is found valuable. The resulting blurred image must then be decoded.

Speech encoding method, speech decoding method and speech encoding/decoding method
The Journal of the Acoustical Society of America, 1998A speech encoding/decoding method calculates a short-term prediction error of an input speech signal that is divided on a time axis into blocks, represents the short-term prediction residue by a synthesized sine wave and a noise and encodes a frequency spectrum of each of the synthesized sine wave and the noise to encode the speech signal.

Voice coder/decoder and methods of coding/decoding
The Journal of the Acoustical Society of America, 1994A new adaptive Fourier transform coder/decoder encodes periodic components of speech signals and decodes the encoded periodic components. The pitch frequency of voice signals in successive time frames at the voice coder may be determined as by (1) Cepstrum analysis (e.g.

Speech decoder and a method for decoding speech
The Journal of the Acoustical Society of America, 2009A speech decoder comprises a decoder (103) for converting a linear prediction encoded speech signal into a first sample stream having a first sampling rate and representing a first frequency band. Additionally it comprises a vocoder (105) for converting an input signal into a second sample stream having a second sampling rate and representing a second ...

Compacted codeword Huffman decoding method for MPEG-2 AAC decoder
2013 IEEE International Conference on Consumer Electronics (ICCE), 2013This paper proposes a new MPEG-2 AAC Huffman decoding algorithm which is designed to find multiple symbols in a single search. The analysis and experimental results show that the computational complexity of the proposed method is lower by more than 46% when compared with those of the up-to-date methods.

Voice encoding method and voice decoding method
The Journal of the Acoustical Society of America, 1996A compressed digital speech signal is encoded to provide a transmission error-resistant transmission signal. The compressed speech signal is derived from a digital speech signal by performing a pitch search on a block obtained by dividing the speech signal in time to provide pitch information for the block.
