Abstract: The paper deals with the problem of measuring the power of band-pass signals; to this aim, a new method, taking advantage of the interesting features of compressive sampling, is presented.

Abstract: Digital image compression reduces the bandwidth, time, and energy needed for transmission of images and signals, as well as memory needed for their storage. However, it cannot solve the ...

We propose a novel hybrid imaging system to acquire 4D high-speed hyperspectral (HSHS) videos with high spatial and spectral resolution. The proposed system consists of two branches: one branch ...

In this paper, a compressed adaptive image-sensing method based on an overcomplete ridgelet dictionary is proposed. Some low-complexity operations are designed to distinguish between smooth blocks and ...

One of this century's most significant mathematical discoveries may reduce the number of measuring points to one-sixth of the present level. This means reduced exposure to radiation and faster medical ...

Many of our academics speak to the media as experts in their field of research. If you are a journalist, please contact the University’s Media and PR Team: My main research interests revolve around ...
