Video and Image Processing

Overview

The group works on improving and developing new methods of acquisition and manipulation of images and other signals from cameras and microscopes to extract and enhance information. We develop instrumentation and algorithms to analyse signals, images and video from multidisciplinary domains such as marine science, arts and heritage, medicine, and sports.

The Compressed Sensing and Imaging Team headed by Dr. Ritz Ann Aguilar develops algorithms for signal compression to save data storage as well as lessen data acquisition and processing time. The group builds their own instrumentation for imaging applications within and beyond the visible spectrum using single-pixel detectors, spatial light modulators, and analog-to-digital converters. The combined instrumentation and developed methods are to be used for computational ghost imaging, a.k.a. single-pixel imaging, an alternative for conventional digital imaging.
