Is the pixel about to die?: "Digital pictures are built from a rectangular grid of coloured cells, or pixels. The smaller and closer the pixels are together, the better the quality of the image. So pixel-based movies need huge amounts of data and have to be compressed, losing visual quality. They are also difficult to process.
The alternative, a vector-based format, presents the image using contoured colours. Until now there has not been a way to fill in between the colours at the quality needed for professional use. The Bath team has finally solved this problem.
A codec is a computer programme capable of encoding or decoding a digital video stream. The researchers at Bath have developed a new, highly sophisticated codec, which is able to fill between the contours, overcoming the problems previously preventing their widespread use. The result is a resolution-independent form of movie and image, capable of the highest visual quality but without a pixel in sight."
