Being interested how JPEG mini performs and works, I ran some super-scientific experiments with the Lena image. JPEG mini claim to reduce the size of compressed photos by up to 5x while maintaining the perceptual image quality.

I used IJG's cjpeg program for baseline compression (denoted JPEG) with a given JPEG quality. opt. JPEG refers to the optimized Huffman table option of the cjpeg program, smooth JPEG makes use of the smoothing (factor 30) and optimization of cjpeg.

On to the results: JPEG mini succeeds to reduce the JPEG file size, especially for very high quality factors. The perceptual quality is harder to judge, a significant drop in PSNR can be measured. The scientific aspect is the usage of the Lena image obviously.

I just became aware of a book chapter authored by Dan Grois and Ofer Hadar, Recent Advances in Watermarking for Scalable Video Coding, Watermarking - Volume 2, Intech Open Access, ISBN: 978-953-51-0619-7, edited by Mithun Das Gupta (DOI 10.5772/37543).

The chapter summarizes large parts of my work: nice, thanks. On the other hand, three figures from my papers are redrawn and reproduced and several sentences are restated in full (and cited).

The 13th Information Hiding conference in Prague was very interesting (latest results on fingerprinting and steganography unveilling all secrets of BOSS) and enjoyable thanks to the excellent organization and social program.

Slides are available.
