Title: | Implementació d'un sistema per al control de la qualitat d'imatges JPEG |
Author: | Pino Lacosta, Jordi |

Abstract: | The standard JPEG is the graphic format for fixed footage of continual key that utilises as a mode of publication at the web. The nice account among the reason of compression obtained and the quality of the image compressed and the wide diffusion among the users of Internet, have converted it at the standard for the compression of footage. The user, but, only can control the final quality for the method of assay-error and this process has an overhead computational cost since the image has to compress , decompress and next compound the half quadratic error. This work provides a bookshop of basic routines that permits to modify the matrix of quantization at function of the characteristics of the image, of the perception of the observer and of the level of quality desired by the user, without penalising the reason of compression and with reasonable computational costs. |
Keywords: | images JPEG quantization matrices images quality check |
