Surveillance and Monitoring Using Video Images from a UAV
We present a methodology to perform the analysis of a video stream, as generated by an Unmanned Air Vehicle observing a theater of operation. The goal of this analysis is to provide an alert mechanism to a human operator. We propose to first detect independently moving objects, then to track and classify them, and to infer behaviors using context. We propose to use, as context, the information ...
متن کاملCompression of Digitized Map Images
-An efficient way to store and retrieve digitized chart images using a lossy vector quantization 0/Q) compression technique is presented. A VQ codebook is located using the fast pairwise nearest neighbor (PNN) clustering algorithm. A k-d tree data structure is used for efficient image compression. Some unique features of this approach are that compressed files use a predictable amount of storag...
متن کاملVideo-Based Monitoring of Pedestrian Movements at Signalized Intersections
Pedestrian and cyclist crossing characteristics are important for the design of urban intersections and signalized crossings. Parameters, such as waiting time, crossing time, and arrival rate are key variables for describing pedestrian characteristics and improving crossing design and signal timing plan. Manually collecting such data is often extremely labor intensive. Therefore, we introduce a...
متن کاملMonitoring eye movements during fMRI tasks with echo planar images.
Verifying task compliance during functional magnetic resonance imaging (fMRI) experiments is an essential component of experimental design. To date, studies of oculomotor tasks such as smooth pursuit eye movements have either measured task performance outside the magnet and assumed similar performance during functional neuroimaging, or have used MR-compatible eye movement recording devices, whi...
متن کاملMicrocalcifications Detection in Digitized Mammographic Images
A method has been developed to detect and analyse microcalcifications in digitized mammographic images. The algorithms presented in this work combine an image preprocessing to denoise the digital image and image treatment techniques to localize and characterize the features of the microcalcifications. Two image denoising methods have been applied to the mammographies, the first one is an adapti...
