Multi-scale Representation and Persistency for Shape Description

2008
Extraction, organization and exploitation of topological features are emerging topics in computer vision and graphics. However, such kind of features often exhibits weak robustness with respect to small perturbations and it is often unclear how to distinguish truly topological features from topological noise.

Multi-scale terrain representation and terrain analysis

SPIE Proceedings, 2009
Multi-scale handling and representation of terrain is one of the key hot topics in GIS. It can meet the demand of different users on the different scale geo-spatial data. Through multi-scale representation of terrain the non-scale GIS can be achieved and the users can acquire the info they care about easily by such GIS.

Multi-scale representations of the motion trajectory

SPIE Proceedings, 2007
At present, mobile computation is developing rapidly for location-based services. For the online GIS or cartography of moving objects, the techniques of progressively refined details greatly reduce the overhead of storage, computation, display, and communication resources.

Multi-scale surface representation of point-sampled geometry

ISPA 2005. Proceedings of the 4th International Symposium on Image and Signal Processing and Analysis, 2005., 2005
With increasing complexity of 3D geometric models and growing demand for advanced modeling functionality, significant effort is being devoted to the design of efficient, reliable, and scalable algorithms for digital geometry processing. We introduce a multi-scale surface representation that enables sophisticated editing functionality at different ...

Multi-scale Corner Detection Using Triangle-area Representation

2009 Third International Symposium on Intelligent Information Technology Application, 2009
In this paper we propose a novel technique for the corner detection of plane curves. This corner detector is given through the triangle-area representation method, whose underlying idea rests on the maximum property of the local area at the corner point. Therefore, the method can be realized easily and is of high accuracy under some appropriate scale (

Multi-scale pyramid pooling for deep convolutional representation

2015 IEEE Conference on Computer Vision and Pattern Recognition Workshops (CVPRW), 2015
Compared to image representation based on low-level local descriptors, deep neural activations of Convolutional Neural Networks (CNNs) are richer in mid-level representation, but poorer in geometric invariance properties. In this paper, we present a straightforward framework for better image representation by combining the two approaches.

A Novel Multi-scale Representation for 2-D Shapes

2007
We present an original approach for 2-D shapes description. Based on a multi-scale analysis of closed contours, this method deals with the differential turning angle. The input contour is progressively low-pass filtered by decreasing the filter bandwidth. The output contour thus becomes increasingly smooth. At each iteration of the filtering we extract

Learning multi-scale sparse representation for visual tracking

2014 IEEE International Conference on Image Processing (ICIP), 2014
We present a novel algorithm for learning multi-scale sparse representation for visual tracking. In our method, sparse codes with max pooling are used to form a multi-scale representation that integrates spatial configuration over patches of different sizes.

Efficient Texture Representation Using Multi-scale Regions

2007
This paper introduces an efficient way of representing textures using connected regions which are formed by coherent multi-scale over-segmentations. We show that the recently introduced covariance-based similarity measure, initially applied on rectangular windows, can be used with our newly devised, irregular structure-coherent patches; increasing the ...
