This paper proposes an affine invariant matching algorithm for shape correspondence problems in arbitrary dimensions. Formulating shapes by configuration matrices of landmarks, and using the fact that subspaces (e.g. range spaces) of these matrices are invariant to affine transformations, the shape correspondence is modelled as a permutation relation(More)
We present an architecture for online, incremental scene modeling which combines a SLAM-based scene understanding framework with semantic segmentation and object pose estimation. The core of this approach comprises a probabilistic inference scheme that predicts semantic labels for object hypotheses at each new frame. From these hypotheses, recognized scene(More)
With the increasing use of online communication platforms, such as email, twitter, and messaging applications, we are faced with a growing amount of data that combine content (what is said), time (when), and user (by whom) information. An important computational challenge is to analyze these data, discover meaningful patterns, and understand what is(More)
In the digital age with a wide array of information never before so openly and easily accessible by the general public, students are allowed to access and reference other people's ideas and works in their learning processes more than ever before in human history. This paper seeks to explore how learning from others in an educational setting could possibly(More)
In order to promote the reuse ability of software, the domain engineering-based development method is used. A design architecture and software architecture in domain information system are presented. The paper emphasizes model architecture of domain information system and the design of the general component library. The system implements a general component(More)
