I shaH that in a monetary grol.,rth model Edgel..'Orthsubstitutability betl.,reen consumption and real balances do not in general imply multiple steady state solutions as has been Hidely believed following Drock (1974). I then show that when the government budget constraint is explicit and the deficit is money-financed with fixed real coupons on outstanding bonds, it is not possible to rule out...

In this paper, we propose a variational model for object segmentation using the active contour method, a geometric shape prior and the Mumford-Shah functional. We propose an energy functional composed by three terms: the first one is based on image gradient, which detects edges, the second term constrains the active contour to get a shape compatible with a statistical model of the target shape,...

New image denoising models based on non-local image information have been recently introduced in the literature. These so-called ”non-local” denoising models provide excellent results because these models can denoise smooth regions or/and textured regions simultaneously, unlike standard denoising models. Standard variational models s.a. Total Variation-based models are defined to work in a smal...

SHAH, KUNAL DEEPAK. Image Processing for Cognitive Models in Dynamic Gaming Environments. (Under the direction of Dr. Robert St. Amant). Cognitive models have typically dealt with environments that are either artificial or real but too simplistic. This stems from the fact that the process of describing the environment to the cognitive model is a complex vision problem. In order to realize the f...

Ionisation in collisions of alpha particles with hydrogen atoms has been investigated for impact energies lying between 2 and 900 keV amu-l. The multistate semiclassical impact parameter model with a two-centre expansion in travelling atomic orbitals was employed. The computed ionisation cross sections are, in particular in the low-energy region, in good agreement with the recent experimental d...

We propose a new variational model for segmenting objects of interest from color images. This model is inspired by the geodesic active contour model, the region-scalable fitting model, the weighted bounded variation model and the active contour models based on the Mumford-Shah model. In order to segment desired objects in color images, the energy functional in our model includes a discriminatio...
