Image series prediction via convolutional recurrent neural networks with limited training data
… algorithms that can be used to forecast the image series under limited training data. Specifically, we study the problem of using a pine tree's existing appearance images to predict its future appearance images.</p>

Temporal registration for MRI time series
Time-course analysis in medical image series often suffers from serious motion. Registration provides voxel correspondences among images, and is commonly employed for correcting motion in medical images. Yet, the registration procedure fails when aligning volumes that are substantially different …

Full Scale Investigation of Bilge Keel Effectiveness at Forward Speed
… with full results in the appendices. Particle image velocimetry (PIV) was also performed during the test and was used to measure the flow field in a three foot by three foot area under the aft end of the same bilge keel. Selected image series are presented, as is a methodology for using these …

Pilvinės aortos aneurizmos automatinės detekcijos nauda matuojant aneurizmos tūrį. Literatūros apžvalga ir modelio sukūrimas /
… and pelvic computed tomography angiography (CTA) images from 10 patients with abdominal aortic aneurysms (totaling 20 CTA image series) were utilized. Aortic and common iliac artery volumes were calculated manually in all patients using the 3mensio and OsiriX software and automatically using the …

Rank constrained denoising in magnetic resonance imaging
… For denoising magnitude diffusion weighted image series, we utilize both low-rank and edge constraints within a maximum a posteriori (MAP) framework. We propose a fast novel majorize-minimize (MM) algorithm to solve the resulting optimization problem by majorizing the log-likelihood from the …

Observation des influences du changement du couvert forestier sur le comportement hydrologique de grands bassins versants tropicaux à l'aide de la télédétection numérique cas du bassin versant de Dong Nai, Viet Nam
… show that a fusion between TM and ETM+ Landsat image series and hydro-meteorologic data allow us to observe and detect flooding trends and flooding peaks after an intensive forest cover change from 16% to 20%. Flooding frequency and flooding peaks have clearly decreased when there is an increase …

Implementation,Validation and Application of an Automated Motion Correction Algorithm in Hepatic Perfusion CT for Image-Guided Radiotherapy
… generated by applying a model to a dynamic series of contrast enhanced anatomical images. The objectives of this thesis are: 1) to develop and validate a registration algorithm to reduce breathing motion artifacts in hepatic perfusion CT, and 2) to evaluate the potential of perfusion CT to …

Image-Based Geotechnical Constitutive Model Parameter Calibration
… simplistic constitutive models. In this thesis, image-based geotechnical constitutive model parameter calibration has been experimentally trialled for realistic soil behaviour. To target strain-softening behaviour, episodic cyclic T-bar penetration testing was selected as a suitable boundary …

Multi-Microscopy Characterisation of III-Nitride Devices and Materials
… which provided fewer issues in terms of image series alignment but also the presence of reconstruction artefacts which must be taken into account when quantitatively analysing the data. The use of correlative techniques was also used to establish the link between high Si content in an …

The role of aerothermochemistry in double cone and double wedge flows
… and a supersonic shear layer. From these images, a separation zone length scaling parameter is determined. This parameter, derived for wedge geometries, is successfully applied to conical geometries by using a judicious choice of flow properties for scaling. In the wedge image series, …
