Several phenomena can be described by a number of densities (of mass, population, probability, ...) distributed in a domain and subject to di↵usion, reaction, and either cooperative or competitive interaction. Whenever the interaction is the prevailing mechanism, one can reasonably expect pattern formation and, in the competitive case, that the several densities can not coexist and tend to segr...

This paper presents a new approach to segmentation using explicit hypotheses about the physics that creates images. We propose an initial segmentation that identifies image regions exhibiting constant color, but possibly varying intensity. For each region, we propose a set of hypotheses, each of which specifically models the illumination, reflectance, and shape of the 3-D patch which caused tha...

Vision should provide an explanation of the scene in terms of a causal semantics|what aaects what, and why. An important part of the causal explanation of static scenes is what supports what, or, counterfactu-ally: Why aren't things moving? We use simple naive physical knowledge as the basis of a vertically integrated vision system that explains arbitrarily complex stacked block structures. The...

Multilook processing is commonly used in SAR image formation in order to reduce the speckle noise. We propose two new mutlilook techniques for improving the radiometric resolution without altering the geometric resolution and characteristics of the impulse response. These techniques are based on the formation of looks with different bandwidths. The final image is formed by giving each look a pr...

primary sedimentary and secondary structural and diagenetic processes are responsible for heterogeneity in carbonate reservoirs and recognition of these factors is very essential subject in modeling these reservoirs. image logs are very useful for identification of structures and small scale sedimentary features. in this research, using image analysis of formation microimager log (fmi) in a dri...

One of the major issues related to dehazing methods (single or multiple image based) evaluation is the absence of the haze-free image (ground-truth). This is also a problem when it concerns the validation of Koschmieder model or its subsequent dehazing methods. To overcome this problem, we created a database called CHIC (Color Hazy Image for Comparison), consisting of two scenes in controlled e...

anima and animus are two ancient and very famous models in literature, which were first proposed by psychologists like jung. this image has been repeatedly presented by researchers out of the poems of different poets. the ancient pattern anima is a semi female part of men and animus is the semi male part of women. the formation of these ancient patterns is influenced by the mother and father an...
