Lossy compression techniques reduce the size of large scientific datasets by selectively discarding or coarsening data elements that contribute least to the overall information content. Unlike ...

While the majority of people use their digital cameras to shoot JPEG files, serious photographers swear by RAW, which offers much increased possibilities in post processing. But while RAW images are ...

It used to be that memory and storage space were so precious and so limited of a resource that handling nontrivial amounts of text was a serious problem. Text compression was a highly practical ...

With the introduction of Qualcomm’s aptX Lossless technology, Bluetooth headphone customers will finally join their wired audiophile brethren with the option to listen to lossless quality audio. The ...

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. The world is generating 2.5 quintillion bytes of data ...

Compression algorithms for speech, audio, still images, and video are quite complicated and, more importantly, nearly always lossy. Thus, samples often change dramatically once they’re decompressed.

Yes, I understand why the initial compression of a bitmap (not necessarily a .BMP) to a JPEG is lossy, via the quantization step after DCT. But if I decompress a JPEG back to a new bitmap, and then re ...
