Collaborative learning by boosting in distributed environments
In this paper we propose a new distributed learning method called distributed network boosting (DNB) algorithm for distributed applications. The learned hypotheses are exchanged b...

Cone-restricted subspace methods
In pattern recognition, feature vectors are occasionally subject to non-negative constraints. This characteristic can be expressed by a cone in feature vector space. In this paper...

Locally invariant texture analysis from the topographic map
In this paper, we present a set of texture features that are locally invariant to similarity or affinity. The proposed indexing scheme relies on the topographic map, a shape-based...

IBR-based free-viewpoint imaging of a complex scene using few cameras
This paper proposes a free-viewpoint imaging method that can be used in a complicated scene such as an office room by using sparsely located cameras. In our method, a free-viewpoi...

Bag-of-visual-words models for adult image classification and filtering
We present a method to classify images into different categories of pornographic content to create a system for filtering pornographic images from network traffic. Although differ...

Force histograms computed in O(NlogN)
The relative position between two objects in a 2D raster image is often represented quantitatively by a force histogram. In the general case, force histograms are computed in O(KN...

New extensions of the 3-simplex for exterior orientation
Object pose may be determined from a set of 2D image points and corresponding 3D model points, given the camera's intrinsic parameters. In this paper, two new exterior orient...

3D Shape Context and Distance Transform for action recognition
We propose the use of 3D (2D+time) Shape Context to recognize the spatial and temporal details inherent in human actions. We represent an action in a video sequence by a 3D point ...
