Many methods of lossy compression have been developed; however, a family of techniques called transform compression has proven the most valuable. The best example of transform compression is embodied ...

Lossless data-compression programs search through documents for redundant or repetitive data and then encode it. For example, a text document may contain 200 empty spaces, 100 instances of the ...

Woodcliff Lake, New Jersey — July 10, 2025 — Semiconductor intellectual property core provider CAST invites electronic system ...

The different types of compression can have a huge effect on your big data transfers. Knowing what types to use is important for your business.

Data compression is the science of shrinking. Compression makes the data that creates images, sounds, video and even text small enough to be sent through telephone wires--the network of the Internet.

A quantum analogue of data compression has been demonstrated for the first time in the lab. Physicists working in Canada and Japan have squeezed quantum information contained in three quantum bits ...

What does data compression actually mean? Find out inside PCMag's comprehensive tech and computer-related encyclopedia.

Images transmitted over the world wide web are an excellent example of why data compression is important. Suppose we need to download a digitized color photograph over a computer's 33.6 kbps modem. If ...

We will describe the operation of JPEG to illustrate how lossy compression works. We have already discussed a simple method of lossy data compression, coarser sampling and/or quantization (CS&Q in ...
