METHOD AND APPARATUS FOR IMPROVING HIGHLY COMPRESSED JPEG FORMAT IMAGES

摘要

The invention relates to a method for compressing an original image file, characterised in that it comprises a step 200 for obtaining a JPEG compressed image file, of maximum size TF, or having a PSNR (peak signal-to-noise ratio) previously chosen by a user, which involves determining a quality QF making it possible to obtain a size that is within a predefined distance from the maximum size, and optimising the calculation time.
