Abstract Background and Objective Identifying liver regions from abdominal computed
tomography (CT) volumes is an important task for computer-aided liver disease diagnosis …

The present paper proposes a new non-optimal but unsupervised algorithm, called ICT-
RDP, for generation of polygonal approximations based on the convex hull. Firstly, the new …

Here we present a novel, information-theoretic salient line segment detector. Existing line
detectors typically only use the image gradient to search for potential lines. Consequently …

The present paper proposes a new algorithm for automatic generation of polygonal
approximations of 2D closed contours based on a new thresholding method. The new …

This paper presents a novel initial dominant point detection technique for polygonal
approximation in digital planar curves. This technique concentrates on the local and global …

This paper presents a viable alternative solution for dominant point detection predicated on
the comparison of suboptimal feature selection methods. Suboptimal feature selection …

This paper presents a fast and progressive polygonal approximation algorithm for online
strokes. A stroke is defined as a sequence of points between a pen-down and a pen-up. The …

On the visual perception, the real-world objects are the collection of irregular polygons.
Representation and understanding the irregular polygon is an interesting and major task in …

A new method for the polygonal approximation is presented. The method is based on the
search for break points through a context-free grammar, that accepts digital straight …

This paper presents an iterative smoothing technique for polygonal approximation of digital
image boundary. The technique starts with finest initial segmentation points of a curve. The …
