Optimal Index Assignment for Multiple Description Lattice Vector Quantization
Optimal index assignment of multiple description lattice vector quantizer (MDLVQ) can be posed as a large-scale linear assignment problem. But is this expensive algorithmic approa...

Rate Bounds on SSIM Index of Quantized Image DCT Coefficients
In this paper, we derive bounds on the Structural SIMilarity (SSIM) Index as a function of quantization rate for fixed-rate uniform quantization of image discrete cosine transform...

Use of normalization methods for analysis of microarrays containing a high degree of gene effects
Background: High-throughput microarrays are widely used to study gene expression across tissues and developmental stages. Analysis of gene expression data is challenging in these ...

Perceptual soft thresholding using the structural similarity index
In this paper, we present a novel algorithm for wavelet domain image denoising using the soft thresholding function. The thresholds are designed to be locally optimal with respect...
