Cluster-based Segmentation of Natural Scenes
نویسندگان
چکیده
In cluster-based segmentation pixels are mapped into various feature-spaces whereupon they are subjected to a grouping-algorithm. In this paper we develop a robust and versatile non-parametric clustering algorithm that is able to handle the unbalanced and irregular clusters encountered in such segmentationapplications. The strength of our approach lies in the de nition and use of two cluster-validity indices that are independent of the cluster-topology. By combining them, an excellent clustering can be identi ed, and experiments con rm that the associated clusters do indeed correspond to perceptually salient image-regions.

متن کامل3-D Colour-based Segmentation and Recognition for Environmental Monitoring
This work focuses on the automatic monitoring of the natural environment using images of animals. An unsupervised 3D colour texture segmentation and recognition algorithm is developed and applied in the recognition of natural patterns (monkeys) in outdoor image scenes (Amazon Forest). We present an unsupervised segmentation algorithm, which uses 3D Graph-theoretical clustering for colour images...
متن کاملUnsupervised Natural Image Segmentation Using Mean Histogram Features
A new histogram feature based natural image segmentation algorithm has been proposed. The proposed scheme uses histogram based new color texture extraction method which inherently combines color texture features rather then explicitly extracting it. A non parametric Bayesean clustering is employed to make the segmentation framework fully unsupervised where no a priori knowledge about the number...
متن کاملA Concurrent Region Growing Algorithm Guided by Circumscribed Contours
Image segmentation of natural scenes constitutes a major problem in Machine Vision. This paper presents a new proposal for the image segmentation problem which has been based on the integration of edge and region information. This approach begins by detecting the main contours of the scene which are later used to guide a concurrent set of growing processes. A previous analysis of the seed pixel...
متن کاملSegmentation of satellite imagery of natural scenes using data mining
In this paper, we describe a segmentation technique that integrates traditional image processing algorithms with techniques adapted from knowledge discovery in databases (KDD) and data mining to analyze and segment unstructured satellite images of natural scenes. We have divided our segmentation task into three major steps. First, an initial segmentation is achieved using dynamic local threshol...
متن کاملColor Image Segmentation Using Multispectral Random Field Texture Model & Color Content Features
This paper describes a color texture-based image segmentation system. The color texture information is obtained via modeling with the Multispectral Simultaneous Auto Regressive (MSAR) random field model. The general color content characterized by ratios of sample color means is also used. The image is segmented into regions of uniform color texture using an unsupervised histogram clustering app...
