Optimum word length allocation for multipliers of integer DCT
Recently, the integer DCT (Int-DCT), which has the rounding operations in the lifting structure, is attracting many researchers' attention as an effective method for DCT base...

Overcompressing JPEG Images with Evolution Algorithms
Abstract. Overcompression is the process of post-processing compressed images to gain either further size reduction or improved quality. This is made possible by the fact that the ...

Learning-based face hallucination in DCT domain
In this paper, we propose a novel learning-based face hallucination framework built in DCT domain, which can recover the high-resolution face image from a single lowresolution one...

High quality scanned book compression using pattern matching
This paper proposes a hybrid approximate pattern matching/ transform-based compression engine. The idea is to use regular video interframe prediction as a pattern matching algorit...

Game-theoretic analysis of a semi-fragile watermarking scheme based on SCS
Semi-fragile watermarking can be used to detect illegal and local manipulation of images, while being robust towards legal manipulations such as lossy compression. This paper desc...
