Clustering by Principal Curve with Tree Structure (2008)
Ioan Cleju, Pasi Fränti, Xiaolin Wu
Abstract—Data clustering is intensively used in signal processing in tasks such as multimedia compression, segmentation and pattern matching. In this work we extend the use of principal curves in...
Stochastic Optimization of Multiple Texture Registration Using Mutual Information (2008)
Abstract. We consider the problem of simultaneously registering several images to a 3D model. We propose a global approach based on mutual information that extends previous methods to incorporate the...
Abstract Evaluation of Supra-Threshold Perceptual Metrics for 3D Models (2008)
Measures of dissimilarity of 3D models are necessary in a wide range of applications such as geometry compression, simplification, and 3D model retrieval. In many cases a metric that models...
Clustering based on principal curve (2005)
Ioan Cleju, Pasi Fränti, Xiaolin Wu
Abstract. Clustering algorithms are intensively used in the image analysis field in compression, segmentation, recognition and other tasks. In this work we present a new approach in clustering vector...
