A new two‐dimensional chaotic system in the form of a cascade structure is designed, which
is derived from the Chebyshev system and the infinite collapse system. Performance …

With the increasing demand for user recognition in several recent applications, experts
highly recommend using biometric identification technology in application development …

In the last decade, several research papers have been published to overcome the limitation
of uncontrolled environments in automatic face recognition. Despite that, the problem of …

With the development of mobile Internet and intelligent mobile devices, mobile iris
recognition is a new advanced frontier for identification. This paper presents an iris …

Iris texture is one of the most secure biometric characteristics used for person recognition,
where the most significant step in the iris identification process is effective features …

The analysis of the iris images of individuals has proven that iris is very distinctiveness and
permanence for biometric uses. The task of iris analysis requires precise steps to yield …

In spite of the prominence and robustness of iris recognition systems, iris images acquisition
using heterogeneous cameras/sensors, is the prime concern in deploying them for wide …

In this work, we present an accurate and novel edge detection technique for gray-scale
images using partial sum of Taylor series expansion (TSE). Taylor's expansion theory gives …

Welding spatter seriously affects the surface quality of the product. Aiming at the automatic
detection problem of spatter on welding plate surface, an in-situ detection algorithm of …

In this paper, a new approach based on an improved fractal dimensions (FDs) for an iris
recognition system is proposed. Improved FDs, based on a differential box-counting (DBC) …
