The case for smartwatch-based diet monitoring
We explore the use of gesture recognition on a wrist-worn smartwatch as an enabler of an automated eating activity (and diet monitoring) system. We show, using small-scale user studies, how it is…

DietCam: Multi-View Food Recognition Using a Multi-Kernel SVM
Food recognition is a key component in evaluation of everyday food intakes, and its challenge is due to intraclass variation. In this paper, we present an automatic food classification method, DietCam, which specifically addresses the variation…
Development of primary glaucoma classification technique using optic cup & disc ratio
Glaucoma is Eye dieses & one of the leading causes of blindness worldwide. It is due to the increase in intra ocular pressure within the eyes. The detection and diagnosis…
Optimizing the Electrical Stimulation of Retinal Ganglion Cells
Epiretinal prostheses aim to restore visual perception in the blind through electrical stimulation of surviving retinal ganglion cells (RGCs). While the effects of several waveform parameters (e.g., phase duration) on…
Fast large-scale multimedia indexing and searching
Searching for digital images in large-scale multimedia database is a hard problem due to the rapid increase of the digital assets. Metric Permutation Table is an efficient data structure for large-scale multimedia indexing. This data…
Towards optimal distortion-based visual privacy filters
The widespread usage of digital video surveillance systems has increased the concerns for privacy violation. Since video surveillance systems are invasive, it is a challenge to find an acceptable balance between privacy…
Analysis of shape assumptions in 3D reconstruction of retina from multiple fundus images
Utilizing priors about the shape of retinal surface is important for accurate reconstruction. We present a detailed analysis of geometrical shape priors in the 3D reconstruction of retina. We first approximate…
Real-Time Emulator for Reproducing Graded Potentials in Vertebrate Retina
In most parts of the retina, neuronal circuits process visual signals represented by slowly changing membrane potentials, or so-called graded potentials. A feasible approach to speculate about the functional roles of…
Big brother for bees (3B) — Energy neutral platform for remote monitoring of beehive imagery and sound
Honey bees have played a major role in the history and development of humankind, in particular for nutrition and agriculture. The most important role of the western honey bee (Apis…
Compact SEPIC converter using a GaN HEMT
The increasing demand for miniaturization in electronic devices has driven the design of compact powersupplies which operate at higher switching frequencies. Gallium-nitride semiconductor switching devices are very promising for increasing the power density and efficiency…
