Human faces provide a useful cue in indexing video content. We present a highly efficient
system that can rapidly detect human face regions in MPEG video sequences. The …

This paper introduces a new algorithm, called lane-finding in another domain (LANA), for
detecting lane markers in images acquired from a forward-looking vehicle-mounted camera …

This paper examines the issue of direct extraction of low level features from compressed
images. Specifically, we consider the detection of areas of interest and edges in images …

In this paper, we attempt to provide a comprehensive and high-level review of audio-visual
features that can be extracted from the standard compressed domains, such as MPEG-1 and …

The approximation of two-dimensional highly correlated grey value functions can be
performed using a linear model of the type f (x, y)= a+ bx+ cy. The set of plane pa-rameters …

Dissimilarity measures, the basis of similarity-based retrieval, can be viewed as a distance
and a similarity-based search as a nearest neighbor search. Though there has been …

An image coding algorithm for digital video tape recorders (DVTR) must satisfy several
requirements which do not arise in other applications of video compression. A key constraint …

An image-coding technique, in which the discrete cosine transform (DCT) is combined with a
classified vector quantization (CVQ), is presented. A DCT-transformed input block is …

An edge preserving image compression algorithm based on an unsupervised competitive
neural network is proposed. The proposed neural network, the called weighted centroid …

The emerging ISO MPEG video compression standard is a hybrid algorithm which employs
motion compensation, spatial discrete cosine transforms, quantization, and Huffman coding …
