This investigation explored the utility of the health locus of control construct in predicting the mental health quality of life (MHQOL) ratings of 72 Latinos living with HIV/AIDS. After controlling for patient CD4 count, viral load, time since diagn

In wavelet-based image coding, a variety of masking properties have been exploited that result in spatially-adaptive quantization schemes. It has been shown that carefully selecting uniform quantization step-sizes across entire wavelet subbands or su

Recent developments in psychovisual modeling have led to improvements in wavelet-based coder performance. A spatially selective quantizer based on texture masking sensitivities is introduced, which hides distortion in high-contrast portions of images

Wavelet-based spatial quantization is a technique to compress image data that adapts the compression to the data in each region of an image. This approach is motivated because quantization with a single step-size does not result in a uniform visual e

In a portable device, such as a digital camera, limitations on storage are an important consideration. In addition, due to constraints on the complexity of available hardware, image coding algorithms must be fairly simple in implementation. This work

Wavelet-based transform coding is well known for its utility in perceptual image compression. Psychovisual modeling has lead to a variety of perceptual quantization schemes, for efficient at-threshold compression. Successfully extending these models

Real-time rate-control requires fast, accurate characterization of the relationship between wavelet subband step-size and rate. A rate-control algorithm is presented based on local properties of the function parameterizing this relationship, the rate

Embedded image coding is a compression technique that yields bit streams robust to truncation. The first embedded wavelet-based compression algorithms were designed to optimize for mean-squared-error (MSE). More recent algorithms incorporate a variet
