Comparison of JPEG’s competitors for document images

Résumé

In this work, we carry out a study on the performance of potential JPEG’s competitors when applied to document images. Many novel codecs, such as BPG, Mozjpeg, WebP and JPEG-XR, have been recently introduced in order to substitute the standard JPEG. Nonetheless, there is a lack of performance evaluation of these codecs, especially for a particular category of document images. Therefore, this work makes an attempt to provide a detailed and thorough analysis of the aforementioned JPEG’s competitors. To this aim, we first provide a review of the most famous codecs that have been considered as being JPEG replacements. Next, some experiments are performed to study the behavior of these coding schemes. Finally, we extract main remarks and conclusions characterizing the performance of these codecs for different contexts in accordance with OCR performance and PSNR metric.
