In this paper, a method for measuring the perceptual image quality of JPEG-2000 coded images has been proposed. The image quality is characterized by the average edgespread in the image, or more specifically the average extent of the slope’s spread of an edge in the opposing gradients’ directions. The proposed method is, in effect, a way of measuring the amount of blurring in the image. The eff...

JPEG2000 is the latest international standard for compression of still images. Although the JPEG2000 codec is designed to compress images, we illustrate that it can also be used to compress other signals. As an example, we illustrate how the JPEG2000 codec can be used to compress electrocardiogram (ECG) data. Experiments using the MITBIH arrhythmia database illustrate that the proposed approach...

Publicly owned companies, their officers and major investors are required to file regular disclosures with the Securities and Exchange Commission (SEC). To improve accessibility to these public documents, the SEC began developed the EDGAR (Electronic Data Gathering, Analysis and Retrieval) electronic disclosure system. This system provides ready, free access to all electronic filings made since...

This paper describes how to extend the performance of a highly energy efficient general purpose DSP by generating accelerators using C-level algorithm descriptions. The result is an equally energy efficient, economical implementation of that algorithm or algorithms.
