A compression technique that does not decompress digital data back to 100% of the original. Lossy methods can provide high degrees of compression and result in smaller compressed files ...

There are two categories of data ... used "lossy" methods that analyze which pixels, video frames or sound waves can be removed forever without the average person noticing (see lossy compression).

Each algorithm delivers a different amount of stored data for the exact same raw video. There are two primary types of compression: lossless and lossy. Determine video needs appropriately How can ...

The current simulations or instruments generate too much data—more than can be properly stored, analyzed, or transferred. There are different approaches to solving the problem. One is called lossless ...

Therefore, we have been investigating lossy data compression techniques as a means of reducing data storage for CESM. Lossy compression, by definition, does not exactly preserve the original data, but ...

As long as you don’t mind a mild amount of definitely noticeable data loss, check out [Greg Kennedy]’s Lossy Text Compression which simply, brilliantly, and amusingly uses a thesaurus instead ...
