Lossless Compression of Dynamic PET Data
We describe two approaches to lossless compression of dynamic PET data. In the first, a sequence of sinogram frames are compressed using differential encoding followed by lossless entropy-based compression. The second approach applies lossless compression to data stored in a sinogram/timogram format in which the arrival times of each photon pair are stored in spatial order, indexed by the sinog...
متن کاملLossless Compression of List-Mode 3D PET Data
We describe lossless methods for compression of 3D PET data. Static list-mode data is re-sorted into sinograms and compressed using a combination of run-length and entropic coding. Dynamic list-mode data is compressed using a sinogram/timogram format in which the arrival times of each photon pair are stored in spatial order, indexed by the sinogram. Compression of the timogram is performed usin...
متن کاملLZAC Lossless Data Compression
This paper presents LZAC, a new universal lossless data compression algorithm derived from the popular and widely used LZ77 family. The objective of LZAC is to improve the compression ratios of the LZ77 family while still retaining the family’s key characteristics: simple, universal, fast in decoding, and economical in memory consumption. LZAC presents two new ideas: composite fixed-variable-le...
متن کاملLossless data compression
This thesis makes several contributions to the field of data compression. Lossless data compression algorithms shorten the description of input objects, such as sequences of text, in a way that allows perfect recovery of the original object. Such algorithms exploit the fact that input objects are not uniformly distributed: by allocating shorter descriptions to more probable objects and longer d...
متن کاملLossless Compression of Audio Data
Lossless data compression of digital audio signals is useful when it is necessary to minimize the storage space or transmission bandwidth of audio data while still maintaining archival quality. Available techniques for lossless audio compression, or lossless audio packing, generally employ an adaptive waveform predictor with a variable-rate entropy coding of the residual, such as Huffman or Gol...
