A Watermarking Scheme Based on the Characteristic of Addition among DCT Coefficients
Generally, low frequency domain may be useful to embed a watermark in an image. However, if a watermark is embedded into low frequency components, blocking effects may occur in the...

Superresolution images reconstructed from aliased images
In this paper, we present a simple method to almost quadruple the spatial resolution of aliased images. From a set of four low resolution, undersampled and shifted images, a new i...

Effect of network structure on the stability margin of large vehicle formation with distributed control
We study the problem of distributed control of a large network of double-integrator agents to maintain a rigid formation. A few lead vehicles are given information on the desired t...

Adaptive Interleaving for OFDM in TDD Systems
We proposed a novel interleaving technique, namely ada,ptive interleaving, which can break the bursty channel errors more effectively than traditional block interleaving. This new...

K-means clustering via principal component analysis
Principal component analysis (PCA) is a widely used statistical technique for unsupervised dimension reduction. K-means clustering is a commonly used data clustering for unsupervi...
