GPU-accelerated Lossless Image Compression with Massive Parallelization
2023 IEEE International Symposium on Multimedia (ISM)(2023)
摘要
With the rapid increase of digital content like images or videos nowadays, compression technology contributes more to saving storage or transferring time with large-scale data. While some existing methods already achieved a great compression ratio, they are not applicable to certain live applications under low efficiency. In this work, we use massive parallelization to speed up the SOTA baseline FLIF, including bitwise-equivalent speedup and learning-based speedup. Our method achieves $38.7 \times$ throughputs for encoding and $2.45 \times$ throughputs for decoding, compared to the baseline FLIF.
