To do that we use a set of local descriptors invariant to rotation and scale. Each image is described by one feature vector. First, a set of invariant descriptors with respect to rotation and shift are computed for each pixel at different space scales. Then, thr ough nonlinear operations, they are mapped to a higher dimensional space, where they ar e averaged. Fisher’s Linear Discriminants are used to reduce the dimensionality of the feature vectors representing each image. Then the feature vectors distributions, for each class of events, are modeled using Mixtures of Gaussians. Differently from previ ous approaches, we take also color information into account when computing the feature vectors.

Using real-time and near – real-time data in the classroom can bridge this discrepancy by exposing students to process of science based upon scientifically collected data. This allows the classroom to be a synthesis of scientific knowledge and scientific sociology which leads to a scientific understanding of the world (Project 2016, AAAS). This project blends uploaded video footage captured by the Eye-in-the-Sea, narration from the actual scientists and the ability of students to also comment and question with a tool that’s available to anyone with internet access. VoiceThread, the on-line application, facilitates interactive sharing to increase excitement about scientific inquiry of the deep sea for today’s students. The multiple VoiceThreads p...

Environmental sensors have continuously improved by becoming smaller, cheaper, more intelligent, and more reliable.

This technology has significantly advanced studies in animal diversity, distribution and abundance. The method currently used to analyse QVTs is labor intensive and costly, reducing the amount of data from the ROV dive and thus limiting marine ecological research. An automated system for detecting organisms and other objects visible in the videos would address these concerns. With this program, video frames are processed with a neuromorphic-selective attention algorithm, modeled after the human vision system. The candidate locations identified by the attention selection module are subject to a number of parameters. These parameters combined with successful tracking over several frames determine whether detected events are deemed "interesting" or "boring". "Interesting" events are...
