It can represent a string of symbols about as compactly as arithmetic coding. But the encoding and decoding steps are fast, like Huffman codes. Compression ... ANS-based algorithms can be used ...

The discrete cosine transform (DCT) remains a cornerstone of modern image and video compression ... multiplierless algorithms that combine low operational counts with high coding efficiency ...

A team of engineers at Dropbox’s Hack Week re-created the fictional compression schema from HBO ... employees are working on the Pied Piper algorithm. So what’s the problem being solved ...

so the algorithm makes a prediction based on that. It then saves only the delta between this prediction and the real value — formatted to be a good fit for the VP8 arithmetic coder. From the ...
