Several algorithms have been proposed for discovering patterns from trajectories of moving objects, but only a few have concentrated on outlier detection. Existing approaches, in general, discover spatial outliers, and do not provide any further analysis of the patterns. In this paper we introduce semantic spatial and spatio-temporal outliers and propose a new algorithm for trajectory outlier d...

Computer-aided segmentation of cardiac images obtained by various modalities plays an important role and is a prerequisite for a wide range of cardiac applications by facilitating the delineation of anatomical regions of interest. Numerous computerized methods have been developed to tackle this problem. Recent studies employ sophisticated techniques using available cues from cardiac anatomy suc...

In this paper, we present an automated system for generating context-preserving route maps that depict navigation routes as a path between nodes and edges inside a topographic network. Our application identifies relevant context information to support navigation and orientation, and generates customizable route maps according to design principles that communicate all relevant context informatio...

Data plays a critical role in organizations up to the point of being considered a competitive advantage. However, the quality of the organizations’ data is often inadequate, affecting strategic and tactical decision making, and even weakening the organization’s image. Nevertheless it is still challenging to encourage management to invest in data quality improvement projects. Performing a tradit...

This paper introduces an approach of creating an image composite by seamlessly blending a region of interest from an image onto another while faithfully preserving the color of regions specified by user markup. With different regions marked for color-preserving, our approach provides users the flexibility in creating different composites. The experiment results demonstrate the effectiveness of ...

This paper introduces a ”Diminished Reality” technique for removing an object or collection of objects and replacing it with an appropriate background image. Diminished Reality can be considered an important part of many Mixed and Augmented Reality applications. Our target application is the use of Augmented Reality (AR) to revamp procedures in industrial plants. An object or a region of intere...

Reuse metrics must accurately reflect the amount of effort saved. We must have realistic measures to ensure the credibility of the value we place on reuse and to separate reuse benefits from those of other technologies also competing for limited investment dollars. This paper defines a reuse metrics and Return On Investment (ROI) model at IBM that distinguishes reuse savings and benefits from t...

We present an application-driven approach to compressing large-scale time-varying volume data. Our method identifies a reference feature to partition the data into space-time blocks, which are compressed with various precisions depending on their association to the feature. Runtime decompression is performed with bit-wise texture packing and deferred filtering. We show that our method achieves ...

We propose an automatic algorithm, named SDI, for the segmentation of skin lesions in dermoscopic images, articulated into three main steps: selection of the image ROI, selection of the segmentation band, and segmentation. We present extensive experimental results achieved by the SDI algorithm on the lesion segmentation dataset made available for the ISIC 2017 challenge on Skin Lesion Analysis ...
