Image quality is a critical issue for the recognition of faces because i.t reduces the risk of forging face recognition systems. The most relevant face spoofing attacks reported in previous studies follow o.ne of the ...

Recognizing identical twins is considered as one of the most critical challenges in biometric systems due to the shortage of uniqueness and distinction between the identical twins. The lack of discriminative features ...

Age group classification is the process of automatically determining an individual’s age range based on features extracted from facial image. It plays an important role in many real-life applications such as age specific ...

Age estimation from facial images is an important application of biometrics. In contrast to other facial variations like occlusions, illumination, misalignment and facial expressions, ageing variation is affected by human ...

Many social interactions and services are dependent on gender today, so, gender classification is appearing as an active research area. Most of the existing studies are based on face images acquired under controlled ...

Digital imaging technology has provided countless opportunities for human visual applications and many scientific disciplines such as astronomy and microbiology. Digital images are subject to various noise due to ...

Multimodal biometric systems aim to improve the recognition accuracy by minimizing the limitations of unimodal systems. There exist many unimodal biometric traits used for person authentication such as face, iris, fingerprint, ...

Plant products have been a major source of food for animals, raw materials for industry and source of revenues to governments. In view of this, careful attention is needed for quality and quantity of plant products. Biotic ...
