Neural networks applications for multimedia processing

Adaptive neural networks (NN) technologies present a unified solution to a broad spectrum of multimedia applications. In this paper we pointed out that current research frontier of multimedia signal processing is shifting from coding (MPEG-1,2,4) to automatic recognition (MPEG-7). Its research domain will cover techniques for object-based representation/coding, segmentation/tracking, pattern detection/recognition, multimodal signals fusion/conversion/synchronization, as well as content-based indexing and subject-based retrieval/browsing. Also, we reported successfully applications of NN for compression, denoising, contrast enhancement, snakes model segmentation/visualization, audio-to-video conversion and content-based processing/indexing/retrieval.
