Quantitative analysis of cerebral white matter anatomy from diffusion MRI
… to anatomical bundles and to establish the point correspondence between these variable-length trajectories. We propose a computationally-efficient approach to find the point correspondence and the distance between each trajectory to the prototype center of each bundle. Based on the computed …

Magnetic resonance imaging and surface-based analysis techniques to quantify growth of the developing brain
… of the cortex are generated at each time point. A novel intra-subject registration algorithm: LAndmark Correspondence and Relaxation Of Surface Strain: LACROSS), which provides a point-to-point correspondence between two surfaces, is applied to the cortical surfaces from two ferret kits. …

LEARNING STRUCTURED ALIGNMENT: FROM VISUAL UNDERSTANDING TO ROBOT CONTROL
… need for methods that can establish meaningful correspondences and relationships across diverse visual modalities and robotic tasks. This dissertation addresses the fundamental challenge of learning structured alignment, which involves establishing correspondences between different …

Vision-Based Rendering: Using Computational Stereo to Actualize IBR View Synthesis
… vision and image-based rendering: an improved point correspondence methodology, an adjacency graph construction algorithm for unordered photographs, a pose estimation ordering for unordered image sets, and an image-based rendering algorithm that interpolates omnidirectional images to synthesize …

Reconstruction of three-dimensional facial geometric features related to fetal alcohol syndrome using adult surrogates
… set. Following rigid registration, a dense point-to-point correspondence across a set of aligned face scans was computed using the Gaussian process model fitting approach. A 3DMM of the face was constructed from the fully registered 3D face scans. The constructed 3DMM of the face was …

Ανάπτυξη τεχνικών επεξεργασίας και ευθυγράμμισης ιατρικών δεδομένων με χρήση χαρτών αυτο-οργάνωσης στην ακτινοθεραπεία
Σκοπός της παρούσας διδακτορικής διατριβής είναι η ανάπτυξη αλγορίθμων επεξεργασίας ιατρικής εικόνας για την ενσωμάτωση τους σε ιατρικές εφαρμογές ακτινοθεραπευτικού ενδιαφέροντος. Οι αλγόριθμοι αυτοί στηρίζονται στην αρχή λειτουργίας των χαρτών αυτο-οργάνωσης Kohonen και αξιοποιούν την πληροφορία …

Two- and Three-dimensional Face Recognition under Expression Variation
… issue, a method is proposed for sampling the points of the face that correspond to the same facial features across all faces, denoted as the closest-normal points (CNPs). It is shown that the performance of the linear discriminant analysis (LDA) method, applied to such an aligned …
