← Back to context Comment by esafak 7 days ago What is color quantization used for in this lossy compression age? 3 comments esafak Reply vanderZwan 7 days ago I don't get the question. Lossy compression uses color quantization all the time, doesn't it? esafak 7 days ago Not typically. JPEG zeros out high frequency DCT coefficients, which is not the same thing. Hence my question: why go through this memory-intensive procedure? qingcharles 7 days ago GIFs
