Biometrics are distinct physiological characteristics used to describe individuals. Compared to the traditional access control methods such as passwords and Person Identification Numbers (PIN) which can be forgotten and shared easily, biometrics ...

Communication networks, play a major role in keeping us connected and sharing the details of our lives with each other. The main driver of multimedia data transmission is to enhance security protection of this multimedia data (speech, image and ...

Countries flags are characterized by a combination of special colors. Building an automatic country flag detector is a hard task because of many challenges like deformation and difference in point of view. Motivated by the unique feature of the ...

Glaucoma, diabetic retinopathy, and other eye diseases have seriously threatened people’s visual health. Whether it is clinical diagnosis or computer-aided diagnosis, the accurate segmentation of the retinal tissues and lesion areas (optic disc (...

A brain tumor is an abnormal growth of cells, reproducing themselves in an uncontrolled manner. In a medical diagnosis system, the accurate detection of location and size plays a very important role in the diagnosis of brain tumors. Magnetic ...

Nowadays, authentication is required for both physical access to buildings and internal access to computers and systems. Biometrics are one of the emerging technologies used to protect these highly sensitive structures. However, biometric systems ...

With billions of devices being connected, how to make sure that our information stays secure is becoming a hot topic of IoT. Traditional approaches to personal authentication are inadequate and ineffective in the IoT era. Finger vein technology is ...

The computer-assisted music composition is an active research area since mid-1900. In this paper, we have applied the VOGUE model for designing musical sequence of bandish notations of raga Bhairav, a classical Indian music. Variable Order and ...

Non-negative matrix factorization (NMF) and its variants have been widely employed in clustering and classification task. However, the existing methods do not consider robustness, adaptive graph learning and discrimination information at the same ...

Soil classification is one of the major affairs and emanating topics in a large number of countries. The population of the world is rising at a majorly rapid pace and along with the increase in population, the demand for food surges actively. ...

Depth-image-based rendering (DIBR) has become an accessible rendering technology for 3D video. A variety of digital watermarking methods have been proposed to protect the copyright of DIBR 3D video works. However, the robustness and ...

High-speed cameras are used in computer vision systems to track balls, shuttlecocks, or players in many different sports. Collected information is used for statistics, as coaches’ and players’ aids to improve technique and tactics or as referees’ ...

Attribute features can be exploited as high-level semantic features to help the model better express person characteristics and improve person re-identification (re-ID) performance. In this paper, a novel activation guided identity and attribute ...

This paper thoroughly introduces a comprehensive review of the so-called Dragonfly algorithm (DA) and highlights its main characteristics. DA is considered one of the promising swarm optimization algorithms because it successfully applied in a ...

Traditional medical image segmentation methods have problems such as low segmentation accuracy and low adaptive ability. Therefore, many scholars have proposed a medical image segmentation method based on deep learning, which has achieved good ...

An image encryption algorithm based on chaotic sequence and permutation matrix is presented in this paper, with the ability to create pseudo-features and realize one-time password mechanism. Firstly, the original image and the matrix which ...

The development of efficient search engine queries for biomedical images, especially in case of query-mismatch is still defined as an ill-posed problem. Vector-space model is found to be useful for handling the query-mismatch issue. However, ...

Underwater images, which have low contrast and visibility as a result of selective attenuation based on the wavelength of the light passing through water, needs some corrections to extract meaningful information from them. In this paper, we aim to ...

In this paper we introduce a cavity reconstructing algorithm for 3D surface scans (CRASS) developed for filling cavities in point clouds representing human body surfaces. The presented method uses Bezier patches to reconstruct missing data. The ...

As an important method of biometric authentication, finger-vein recognition utilizes the unique finger-vein patterns to identify individuals at a high level of accuracy and safety. However, noise components, inherent in finger-vein images, pose a ...
