This paper presents a novel algorithm for computing graph edit distance (GED) in image categorization. This algorithm is purely structural, i.e., it needs only connectivity structure of the graph and does not draw on node ...

Reduced-reference (RR) image quality assessment (IQA) has been recognized as an effective and efficient way to predict the visual quality of distorted images. The current standard is the wavelet-domain natural image ...

Video-based facial expression recognition is a challenging problem in computer vision and human-computer interaction. To target this problem, texture features have been extracted and widely used, because they can capture ...

In web systems development, the business environment and processes not only drive the identification of system needs, but this environment and processes are also in turn fundamentally changed by the introduction or ...

This paper focuses on error correction and concealment technologies for the modern video encoding/decoding standards. In this paper, we present a subblock error concealment method for intra-frames based on an error detection ...

Evaluating multistate flow network reliability and reducing system cost are important tasks when planning and designing systems. Existing methods are based on (d, c)-minimal paths ((d, c)-MP), which are vectors, such that ...
