Technology
PrimaComp has special knowledge, capability, and expertise in wavelet-based data compression. Its founder is the co-inventor of the celebrated Set Partitioning In Hierarchical Trees (SPIHT) coding algorithm, the Set Partitioning Embedded bloCK (SPECK) coding algorithm, and other less-known set partitioning coding algorithms. These algorithms are highly efficient, low in complexity, and flexible, and possess many desirable attributes, such as natural scalability in rate and resolution, region-of-interest encoding and decoding, and random access decoding.
PrimaComp has contributed solutions for data compression and transmission in many fields, among which are data security, healthcare (medical image and signal storage and transmission), video streaming, materials science, space exploration, and oil and gas exploration (mud pulse telemetry).

Software
PrimaComp has exclusive rights and expertise in the following image compression software
SPIHT Software Suite
SPIHT computer programs with different features tailored for specific applications and markets. The source data may range from one to four dimensions. MD-SPIHT
Low-delay, low-complexity codec to encode and decode color or grayscale image sequences and video. |
SPECK Software
Computer programs that implement the SPECK encoder and decoder for two and three dimensions. SPECK possesses many of the same beneficial attributes as SPIHT. SBHP Software
Computer programs that implement the SBHP encoder and decoder for two to four dimensions. SBHP is a variant of SPECK that uses smaller active memory than either SPECK or SPIHT while retaining the same attributes. |
