Most 3D object retrieval and matching methods only consider geometric similarity. This paper introduces a novel descriptor, Shape-Colour Histograms, to match objects with similar shape and appearance. This is motivated by the requirement to concatenate captured 3D video sequences for animation production. A quantitative evaluation based on the Receiver-Operator Characteristic (ROC) curve is presented...
Satellite multi-spectral images which captured from independent camera photography system of satellite have nonlinear errors in spatial position. To this complicated problem, the paper introduces an automatic registration method to match multi-spectral images automatically, in which the mutual information, genetic algorithm and MQ geometric correction models are intergraded. In its algorithm, the...
The problem of 3D shape matching is typically restricted to static objects to classify similarity for shape retrieval. In this paper we consider 3D shape matching in temporal sequences where the goal is instead to find similar shapes for a single time-varying object, here the human body. Local- feature distribution descriptors are adopted to provide a rich object description that is invariant to changes...
This paper introduces a novel 4D shape descriptor to match temporal surface sequences. A quantitative evaluation based on the receiver-operator characteristic (ROC) curve is presented to compare the performance of conventional 3D shape descriptors with and without using a time filter. Feature- based 3D shape descriptors including shape distribution (Osada et al., 2002 ), spin image (Johnson et al...
