Sub-Pixel Classification of Historical and Current Marsh Habitat For the Eastern Mississippi Gulf Coast Using Remotely Sensed Images
… of this project was to complete a historical sub-pixel prediction land use classification map for six land classes: water estuarine emergent wetlands, fresh water wetlands, forests, low intensity developed areas and high intensity developed areas using high spatial resolution imagery and applying …

High performance data processing pipeline for connectome segmentation
… algorithmic techniques for 2- dimensional pixel classification of varying accuracy and speed trade-off, as well as a fast object segmentation algorithm. The majority of the system is parallelized for multi-core machines, and with minor additional modification is expected to work in a …

Partitioned particle filtering for target tracking in video sequences
… observation likelihood is calculated on a per-pixel basis, using sixteen-centered Gaussian Mixture Models trained on the available colour information for each target. Assumptions about the behaviour of each pixel allow for the improvement under certain circumstances of the basic pixel …

Understanding expressive action
… of the human body with modifications to the pixel classification algorithms that enable them to take advantage of this high-level knowledge. The result is a novel vision framework that has no completely bottom-up processes, and is therefore significantly faster and more stable than other …

Vegetation Reflectance Estimation Through Optimization of a Spectral Unmixing Model
… the isolation of the vegetation spectrum by pixel classification, collecting a clean HSI dataset in the field is challenging due to motion artifacts and storage requirements for extensive areas. A compact spectrometer system is a quicker and smaller data size alternative used for high …

Automated dust storm detection using satellite images. Development of a computer system for the detection of dust storms from MODIS satellite images and the creation of a new dust storm database
Dust storms are one of the natural hazards, which have increased in frequency in the recent years over Sahara desert, Australia, the Arabian Desert, Turkmenistan and northern China, which have worsened during the last decade. Dust storms increase air pollution, impact on urban areas and farms as …
