Numerous voice, still image, audio, and video compression standards have been developed over the last 25 years, and significant advances in the state of the art have been achieved. However, in the more than 50 years since Shannon’s seminal 1959 paper, no rate distortion bounds for voice and video have been forthcoming. In this volume, we present the first rate distortion bounds for voice and vi...

Huge amount of video data gets generated every day which needs to be efficiently processed and effectively presented to the users for retrieval of relevant information. The focus of this paper is primarily to explore techniques which can support IR applications on large scale video databases. Almost 25 times faster approximation of a widely used color representation is proposed by using informa...

Multimedia is an emerging service which integrates voice, video and data in the same service. With the progress made in high speed large capacity multimedia servers, high speed networks, QoS, service guarantees and set top boxes, it is currently possible to cost effectively and efficiently carry multimedia over high speed networks. This paper surveys the progress made, and the future of efficie...

Image and video retrieval continues to be one of the most exciting and fastest-growing research areas in the field of multimedia technology. What are the main challenges in image and video retrieval? Despite the sustained efforts in the last years, we think that the paramount challenge remains bridging the semantic gap. By this we mean that low level features are easily measured and computed, b...

In this paper, we propose a new full-fuzzy video ratecontrol algorithm (RCA) for variable bit rate (VBR) videoapplications. The proposed RCA provides high qualitycompressed video with a low degree computational complexity.By controlling the quantization parameter (QP) on a picturebasis, it produces VBR video bit streams. The proposed RCAhas been implemented on the JM H.264/AVC video codec andth...
