This abstract propose as-projective-as-possible warps, i.e., warps that aim to be globally projective, yet allow local non-projective deviations to account for violations to the assumed imaging conditions. Based on a novel estimation technique called Moving Direct Linear Transformation (Moving DLT), our method seamlessly bridges image regions that are inconsistent with the projective model. The result […]
A NOVEL HUB-BASED CLUSTERING FOR HIGH-DIMENSIONAL DATA
Clustering becomes difficult due to the increasing sparsity of such data, as well as the increasing difficulty in distinguishing distances between data points. Hubness is the tendency of some data points in high-dimensional data sets to occur much more frequently in k-nearest-neighbor lists of other points than the rest of the points from the set, […]
2D TO STEREOSCOPIC 3D CONVERSION USING ROBUST SEMI-AUTOMATIC DEPTH MAP GENERATION IN UNCONSTRAINED IMAGES AND VIDEO SEQUENCES
Stereoscopic imaging has been around for many decades, it has recently seen a rise in interest due to the availability of consumer 3D displays and 3D films. This surge is seen in the recent proliferation of big budget 3D movies, or with some portions of the film being offered in 3D. 3D films show novel […]
THE ROLE OF HUB-BASED CLUSTERING FOR HIGH-DIMENSIONAL DATA
Clustering in general is an unsupervised process of grouping elements together, so that elements assigned to the same cluster are more similar to each other than to the remaining data points. In this abstract, we take a novel perspective on the problem of clustering high-dimensional data. Instead of attempting to avoid the curse of dimensionality […]
Privacy Enhanced Participatory Sensing Infrastructure
The outbreak of Wireless Sensor Networks (WSNs) and predicted the widespread installation of sensors, in infrastructures, buildings, woods, rivers, or even the atmosphere. This has triggered a lot of interest in many different WSN topics, including identifying and addressing security issues, such as data integrity, node capture, secure routing, etc. On the contrary, privacy has […]
