Matching Unstructured Vocabularies Using a Background Ontology
Existing ontology matching algorithms use a combination of lexical and structural correspondance between source and target ontologies. We present a realistic case-study where both types of overlap are low: matching two unstructured lists of vocabulary used to describe patients at Intensive Care Units in two different hospitals. We show that indeed existing matchers fail on our data. We then dis...
متن کاملVideo Compression Using Matching
|The use of matching pursuit (MP) to code video using over-complete Gabor basis functions has recently been introduced 8]. In this paper, we propose new functionalities such as SNR scalability and arbitrary shape coding for video coding based on matching pursuit. We improve the performance of the baseline algorithm in 8] by proposing a new search and a new position coding technique. The resulti...
متن کاملVideo tracking using block matching
A tracking algorithm that predicts the object contour using motion vector information is proposed in this paper. Tracking is achieved by predicting the object boundary using motion vectors, followed by contour update, using occlusionsldisocclusion detection. An adaptive block-based approach has been used for estimating motion between frames. An efficient modulation scheme is used to control the...
متن کاملAn Efficient Adaptive Boundary Matching Algorithm for Video Error Concealment
Sending compressed video data in error-prone environments (like the Internet and wireless networks) might cause data degradation. Error concealment techniques try to conceal the received data in the decoder side. In this paper, an adaptive boundary matching algorithm is presented for recovering the damaged motion vectors (MVs). This algorithm uses an outer boundary matching or directional tempo...
متن کاملEnabling Product Comparisons on Unstructured Information Using Ontology Matching
Information extraction approaches are heavily used to gather product information on the Web, especially focusing on technical product specifications. If requesting different sources for retrieving such specifications, the outcome is of varying formats (different languages, units, etc.). The problem of how to bring such information sets into a unique, interchangeable format is not considered in ...
