Shape retrieval with eigen-CSS search
Shape retrieval programs are comprised of two components: shape representation, and matching algorithm. Building the representation on scale space filtering and the curvature function of a closed boundary curve, curvature scale space (CSS) has been demonstrated to be a robust 2D shape representation. The adoption of the CSS image as the default in the MPEG-7 standard, using a matching algorithm...
متن کاملEigen-css Shape Matching and Recognizing Fish in Underwater Video
This thesis presents work on shape matching and object recognition. First, we describe Eigen-CSS, a faster and more accurate approach to representing and matching the curvature scale space (CSS) features of shape silhouette contours. Phase-correlated marginal-sum features and PCA eigenspace decomposition via SVD differentiate our technique from earlier work. Next, we describe a deformable templ...
متن کاملImage Retrieval Using Eigen Queries
Category based image search, where the goal is to retrieve images of a specific category from a large database, is becoming increasingly popular. In such a setting, the query is often a classifier. However, the complexity of the classifiers (often SVMs) used for this purpose hinders the use of such a solution in practice. Problem becomes paramount when the database is huge and/or the dimensiona...
متن کاملAn Eigen-based motion retrieval method for real-time animation
Research on real-time 3D animation is attracting a lot of attention in recent years due to the popularity of emerging applications such as distributed virtual environments and computer games. One of the important issues in real-time animation is that the existing motion retrieval techniques generally have a high matching time because they are typically based on matching time-series, making them...
متن کاملOrdinal-based shape retrieval with relevance feedback
In this paper we propose to incorporate a feedback loop, into the ordinal correlation framework and apply it to shapebased image retrieval. The user’s feedback on the relevance of the retrieval results is used to tune the weights of the similarity measure. Statistics from the features of both relevant and irrelevant items are used to estimate the weights. Moreover, the information accumulated f...
