چکیده

This article describes a novel junction descriptor that encodes junctions’ semantic information in terms incoming lines’ orientations, both in 2D and 3D. A Kalman filter process is used to reduce the effect of local noise on the descriptor’s error and to track the features. The improvement gained by our algorithm is demonstrated quantitatively on synthetic scenes and qualitatively on real scenes.

Spatial and Temporal Evaluation of Water Quality in the Kashkan River

The Kashkan River basin is one of the most important watersheds in the west of Iran, where major urban, agricultural and livestock regions are located in its catchment area. The aim of the study reported here is to evaluate the spatial and long temporal variations of surface water quality in the Kashkan River by using Water Quality Index, which aggregates different parameters and their dimensio...

A Spatial Hypergraph Based Semi-Supervised Band Selection Method for Hyperspectral Imagery Semantic Interpretation

Hyperspectral imagery (HSI) typically provides a wealth of information captured in a wide range of the electromagnetic spectrum for each pixel in the image. Hence, a pixel in HSI is a high-dimensional vector of intensities with a large spectral range and a high spectral resolution. Therefore, the semantic interpretation is a challenging task of HSI analysis. We focused in this paper on object c...

An Intermediate Representation for the Interpretation of Temporal Expressions

The interpretation of temporal expressions in text is an important constituent task for many practical natural language processing tasks, including question-answering, information extraction and text summarisation. Although temporal expressions have long been studied in the research literature, it is only more recently, with the impetus provided by exercises like the ACE Program, that attention...

Extraction of knowledge from Tunisian historical mosaics using fuzzy logic and semantic concepts similarity measure to create a fuzzy metadata

The objective of this this research is to attain a semantic interpretation of images of historical mosaics. We use fuzzy logic techniques and a modified semantic similarity measure to extract knowledge from the images. The extracted knowledge provides experts and laypersons with an intuitive way to describe and to query the images in the database. The knowledge we extract from a mosaic image co...

A Spatial-Temporal-Semantic Neural Network Algorithm for Location Prediction on Moving Objects

Location prediction has attracted much attention due to its important role in many location-based services, such as food delivery, taxi-service, real-time bus system, and advertisement posting. Traditional prediction methods often cluster track points into regions and mine movement patterns within the regions. Such methods lose information of points along the road and cannot meet the demand of ...
