Segmentation of Overlapping Elliptical Objects in Silhouette Images

Image Segmentation of Multi-shaped Overlapping Objects

In this work, we propose a new segmentation algorithm for images containing convex objects present in multiple shapes with a high degree of overlap. The proposed algorithm is carried out in two steps, first we identify the visible contours, segment them using concave points and finally group the segments belonging to the same object. The next step is to assign a shape identity to these grouped ...

Segmentation of Noisy Binary Images Containing Circular and Elliptical Objects using Genetic Algorithms

A segmentation technique basically divides the spatial domain, on which the image is defined in ‘meaningful’ parts or regions. The current approaches involving Genetic Algorithms (GAs) segment the regular-shaped images. In the proposed method, this drawback is overcome by applying GA to images containing circular and elliptical objects. The GA generated the initial population set randomly where...

Part segmentation of objects in real images

This paper addresses one major aspect of a project aimed at the design of an image database query engine, where the images are searched at the 3D object-level. This approach is a novelty since image databases are usually searched by comparing colours, textures and 2D shapes of regions in the images. The main topic and contribution of this paper is a new method for object part segmentation, from...

Multi Resolution Fuzzy Segmentation of Satellite Images

Recognising Objects by their Silhouette

We present an object recognition system that identifies objects by their silhouette from single views of a greyscale camera. The centroidal profile describing the object boundary is matched with boundaries from a model base using a dynamic programming technique. Objects are modelled by a multi-view representation which can either be learned from a set of images or generated from a geometric mod...
