Experimental DCO-OFDM Optical Camera Communication Systems With a Commercial Smartphone Camera

Fingerprint Extraction Using Smartphone Camera

In the previous decade, there has been a considerable rise in the usage of smartphones.Due to exorbitant advancement in technology, computational speed and quality of image capturing has increased considerably. With an increase in the need for remote fingerprint verification, smartphones can be used as a powerful alternative for fingerprint authentication instead of conventional optical sensors...

Smart Appliance Identification using A Smartphone Camera

A Virtual TouchPad for Smartphone with Depth Camera

This paper proposes a virtual touchpad human computer interaction (HCI) based on the fingertip hand gesture recognition (FHGR) method for smartphone with depth camera. The virtual touchpad HCI requires less computing power and memory resource than the conventional hand gesture recognition (HGR) methods. It consists of three modules: (1) open hand identification, (2) active fingertip detection a...

Pedestrians Tracking in a Camera Network

With the increase of the number of cameras installed across a video surveillance network, the ability of security staffs to attentively scan all the video feeds actually decreases. Therefore, the need for an intelligent system that operates as a tracking system is vital for security personnel to do their jobs well. Tracking people as they move through a camera network with non-overlapping field...

A Differential Optical Range Camera

We describe a novel formulation of the range recovery problem, based on computation of the differential variation in image intensities with respect to changes in camera position. The method uses a single stationary camera and a pair of calibrated optical attenuation masks to directly measure this differential quantity. The subsequent computation of the range image is simple and should be suitab...
