In this paper, we propose a robust multi-watermarking method based on vector quantization using an index transform function. In contrast with the conventional watermark embedding methods to embed only one watermark at a time into the original image,

A new stereo matching scheme using a genetic algorithm is presented to improve the depth reconstruction method of stereo vision systems. Genetic algorithms are efficient search methods based on principles of population genetics, i.e. mating, chromoso

The sound levels of TV channels vary greatly according to modulation and demodulation rates. When the television channel or input mode is changed, users have to adjust the volume in order to obtain a proper level of sound. In this paper, an automatic

We propose a two stage motion-based region merging algorithm for content-based coding. It uses a six-parameter motion model and the change image obtained from the conventional change detector. First, the type of each region is decided as one of an ob

Field-based scan conversion converts every field in an interlaced sequence to a progressive format or doubles the field rate from 60 Hz to 120 Hz. This paper proposes the new field-based scan conversion that consists of spatial interpolation based on

This paper presents a hierarchical morphological segmentation algorithm based on PSNR for each region. The algorithm follows a top-down procedure. It first takes into account the global information and produces a coarse segmentation, that is, with a

A new video segmentation algorithm using a combined seg- mentation measure for content-based coding is presented. The com- bined segmentation measure is a weighted sum of intensity, motion, and a change segmentation measure. The change segmentation m
