lipophilic yeast of the genus malassezia (pityrosporum) belongs to the normal flora of human skin and many warm-blooded animals. these fungi can produce a diverse range of diseases that the best known and most frequent of them is pityriasis versicolor, a chronic recurrent skin disease occurring primarily in tropical regions. the genus malassezia has been recently enlarged to include seven disti...

Visual cryptography (VC) is a distinct type of secret sharing scheme which hides secret images in share images such that, when the shares are superimposed, a hidden secret image is revealed. It does not require the complex computational method to decode the secret information. The paper proposes a novel Quick Response (QR) code authentication system using Visual Cryptography. The passwords for ...

With the quick development of computer and electronic techniques, infrared sensor-based object tracking has become a hot research topic in recent years. However, infrared object tracking is still a challenging task due to low resolution, lack of representing information, and occlusion. In this work, we present an adaptive weighted patch-based infrared object tracking scheme. First, the candidat...
