The efficiency in breast cancer from imaging-based computer-aided diagnosis (CAD) has
been revealed in recent years. As a fact, the methods grounded on a single modality …

The gradient vector flow (GVF) model has been widely used in the field of computer image
segmentation. In order to achieve better results in image processing, there are many …

Introduction Gradient vector flow (GVF) has been proven as an effective external force for
active contours. However, its smoothness constraint does not take the image structure into …

The gradient vector flow (GVF) is an effective external force to deform the active contours.
However, it suffers from high computational cost. For efficiency, the virtual electric field (VEF) …

The gradient vector flow (GVF) model has been proven as an effective external force for
active-contour-based image segmentation. However, it suffers from high computation cost …

For active‐contour‐based surgery systems, the success of skin cancer boundary
segmentation depends on the initialization point of the snake model, which is a task …

Liver segmentation from Computed Tomography (CT) images is a crucial step in computer
aided diagnosis. In this paper, an efficient liver segmentation method based on a new active …

The classification of liver disease is of paramount significance for an early diagnosis of
patients. In this paper, suggesting a way for classifying the liver in two categories: normal …

It is critical to differentiate the snake's seeds initialized inside and outside the object of
interest. Obviously, if one can do it for every position in the image, it means that the object …
