In this work we propose a new statistic deformable model that we call discriminant snake for 3D reconstruction in volumetric images. Our discriminant snake generalises the classical snake attracted by edge points, it deforms due to a generalised contour representation. The snake selects and classifies image features by a parametric classifier and each snaxel deforms to minimise the dissimilarit...

We propose a novel external force for active contours, which we call neighborhood-extending and noise-smoothing gradient vector flow (NNGVF). The proposed NNGVF snake expresses the gradient vector flow (GVF) as a convolution with a neighborhood-extending Laplacian operator augmented by a noise-smoothing mask. We find that the NNGVF snake provides better segmentation than the GVF snake in terms ...

BACKGROUND Snake bites are one of the significant health problems in the tropical and subtropical regions. Snake bite is a common medical emergency in Iran, and the epidemiological features and management of such cases vary from region to region. OBJECTIVES This present research study was conducted to obtain new information about the epidemiology of snake bites in the region of Kashan, locate...

Here in this paper we present a snake robot which can autonomously change its gait depending on the terrain. Also we present the design and construction details for the same. Here a custom simulator for the robot and an API for the same was developed which reduced the design and development time. For controlling the Snake robot manually a data glove using accelerometers was developed. The Snake...

Snake venom is a complex mixture of proteins, peptides, enzymes, carbohydrates, and minerals. They contain a variety of chemicals with pharmacological and toxicological properties. The innate immune system is the first line of defense against toxins and microbes. Antibacterial and anticancer proteins produced by snake venom have recently attracted significant attention due to their relevance to...

We report a 44-year-old Western Australian man who suffered a cardiac arrest several hours after a bite by a brown snake. He was successfully resuscitated after bolus administration of undiluted brown snake antivenom. We suggest that an initial bolus dose of at least five ampoules (5000 units) of undiluted brown snake antivenom should be given as primary therapy for cardiac arrest following bro...

OBJECTIVE Infections of snake bite wounds by Shewanella are rarely discussed in the medical literature. This study aims to characterize the presentation and management of Shewanella infections in snake bite wounds. METHOD We retrospectively investigated the microbiology, clinical features, and outcomes of patients with Shewanella infected snake bite wounds admitted to a tertiary medical cente...

In this study, we discover some deficiencies of GVF and GGVF Snake such as it can not capture boundaries like “U” and “S” completely because of the counteraction of some external forces and the influence of the local minimum external forces. Based on analyzing force distribution rules of gradient vector flow, a standard is introduced to distinguish every control point is true or false. An addit...

Many active secretions produced by animals have been employed in the development of new drugs to treat diseases such as hypertension and cancer. Snake venom toxins contributed significantly to the treatment of many medical conditions. Venomous snakes have a bad reputation and rightly so because of their often deadly bites. But what makes a snake’s bite so deadly is the venom. Of the 3000 snake ...
