Iris recognition is a biometric authentication system proving vital for ensuring security and has been employed as an important case to test the algorithms developed in pattern recognition. The unique circular shape of the iris and its time invariance makes it a versatile technique that has an accuracy that can be mathematically proven. Here in this work we propose a new segmentation technique and...
With the recent developments in medicine and biology experiments a large amount of data is gathered in the form of multimedia elements (images, videos). Many algorithms have been developed and adapted based on the system of interest, and often the most challenging feature of the images may be used to facilitate a better analysis of the image. Herein, we developed an image analysis algorithm for quantification...
Transmitting information in a secure way is now both a challenge in everyday life and a beautiful area for research. The type of information may intended to hide may include sensitive information of institutions or private health information of ordinary people. Several algorithms and combination of algorithms have been proposed and tested. Here in this work we propose to hide an image in several other...
Detection of underground objects remains an important task today, particularly when attempting to recover landmines. A Ground Penetrating Radar (GPR) sends short pulses in time domain to detect underground objects by recording the reflected signal and analyzing its properties. GPR traces acquired at different positions in space are combined together to form B-scan images. The presence of objects produce...
