Lossy and lossless image compression using reversible integer wavelet transform In this paper, a reversible integer to integer time domain lapped transform (RTDLT) is introduced. TDLT can be taken as a combination of time domain pre- a... F Sheng - 《IEEE Trans Image Processing》 被引量: ...
LZ77 compression is a lossless image compression meaning it maintains raster values during compression. Abraham Lempel and Jacob Ziv introduced this format in 1977 and we still use it today. Combining the first letter from both last names (LZ) and the year it was invented (1977) is how the ...

Pros and Cons of Lossless Compression The main advantage of lossless compression is you don’t have to worry about degrading the quality of a picture or making it look pixelated. Also, unlike with lossy compression, you can restore an image to its original format without any data loss. ...
