An extension of the traditional color-based visual tracker, i.e., the continuously adaptive mean shift tracker, is given for improving the convenience and generality of the color-based tracker. This is achieved by introducing a probability density function for pixels based on the hue histogram of object. As its merits, the direction and size of the tracked object are easily derived by the princ...

This paper presents a digital watermarking scheme based on a new application of DWT and SVD for color artworks protection. This scheme uses the major features of the two chrominance components where the watermark bits are embedded only into one chrominance component according to the color prevalence rate. In watermark embedding process, more modifications can be done upon the selected chrominan...

The decay rates of P-wave heavy quarkonia to light hadrons are presented to leading order in v and next-to-leading order in αs. They include contributions from both the color-singlet component and the color-octet component of quarkonia. Applying these results to charmonium and using measured decay rates for the χc1 and χc2 by E760, we determine the two nonperturbative decay matrix elements, and...

An unwanted side effect of reversible color space transformation, usually being a sequence of lifting steps, is that while removing correlation it contaminates transformed components with noise from other components. To remove correlation without increasing noise, we integrate denoising into the lifting steps and obtain a reversible image component transformation. For JPEG-LS, JPEG2000, and JPE...

We developed a low bitrate watercolor-like video form, which is constructed with a bi-level Y luminance component and a number of UV chrominance combinations. The bi-level Y-component outlines the features of an image and the UV-combinations describe the basic color information of the image. The UV combinations are dynamically chosen during encoding. The resultant video looks better than bi-lev...

In recent years there has been an astronomical increase in the usage of computers for a variety of tasks. With the advent of digital cameras, one of the most common uses has been the storage, manipulation, and transfer of digital images. The files that comprise these images, however, can be quite large and can quickly take up precious memory space on the computer’s hard drive. In multimedia app...
