The biometric person authentication technique based on the pattern of the human iris is well suited to be applied to any access control system requiring a high level of security. Commercial iris recognition systems are currently employed to allow passengers in some airports to be rapidly processed thru security, to allow access to secure areas, and for secure access to computer networks. With i...

Iris segmentation is a significant phase in the iris recognition process because errors cascade into all subsequent phases. Therefore, it important that are minimised. The U-Net architecture uses deep learning approach was previously adopted for this task, but its performance affected by deformation of images caused various noise factors unconstrained (non-ideal) environments. Scratches, blurri...

Introduction: Pupil and iris disorders form an important category of eye diseases. Accurate segmentation the pupil is first most step in automatic diagnosis diseases related to iris. Most existing methods do not have enough accuracy are sensitive effects noise specular spot reflection. In addition, images used these usually limitations, such as viewing angle . Method: proposed algorithm, a stab...

This paper presents a new biomedical image segmentation method that applies an edge-based level set method. According to low contrast in biomedical images, we mainly make focus on introducing the Laplace operator in external energy of level set method for accurately detecting object edge. A preliminary evaluation of the proposed method mainly performs on gallstone detection and extraction, mamm...

In recent years, image segmentation algorithms are widely used for segmenting the image into different parts which can be used for further analytical purposes. Nowadays, many applications such as iris segmentation for authentication, brain tumor detection and number plate segmentation uses different segmentation methods. Among them level set methods emerged widely due to its efficiency in handl...

Information security is concerned with the assurance of confidentiality, integrity and availability of information in all forms. It provides an identification based on a unique feature or characteristic possessed by the individual. Among various techniques, Iris recognition is a rapidly expanding method of biometric technology. A wide variety of recognition schemes is used to either confirm or ...
