Wavelets/multiwavelets bases and correspondence estimation problem : an analytic study

Correspondence estimation in one of the most active research areas in the field of computer vision and number of techniques has been proposed, possessing both advantages and shortcomings. Among the techniques reported, multiresolution analysis based stereo correspondence estimation has gained lot of research focus in recent years. Although, the most widely employed medium for multiresolution analysis is wavelets and multiwavelets bases, however, relatively little work has been reported in this context. In this work we have tried to address some of the issues regarding the work done in this domain and the inherited shortcomings. In the light of these shortcomings, we propose a new technique to overcome some of the flaws that could have significantly impact on the algorithm performance and has not been addressed in the earlier propositions. Proposed algorithm uses multiresolution analysis enforced with wavelets/multiwavelts transform modulus maxima to establish correspondences between the stereo pair of images. Variety of wavelets and multiwavelets bases, possessing distinct properties such as orthogonality, approximation order, short support and shape are employed to analyse their effect on the performance of correspondence estimation. The idea is to provide knowledge base to understand and establish relationships between wavelets and multiwavelets properties and their effect on the quality of stereo correspondence estimation.

Law and theology in Gilbert of Foliot's (c. 1105/10-1187/88) correspondence

Lord Peter Stein, eminent historian of Roman law, described the interaction of law and theology in the writings of one twelfth-century writer as a kind of 'universal jurisprudence' , The twelfth-century figure to whom he referred was Master Vacarius (c. 1115/2O-c. 1200), well-known English Roman lawyer and Anglo-Norman canonist. While Stein drew this conclusion largely on the basis of an analysis of Vacatius' strictly 'legal' work, the Liber pauperum, I have shown elsewhere, following a systematic study ofVacarius' other works, dealing with maniage, christology and heresy, that, when seen together, they demonstrate a use of law as a universal heuristic device to resolve conflict in law and theology.

Friedrich Hayek and Michael Polanyi in correspondence

Friedrich Hayek and Michael Polanyi corresponded with each other for the best part ofthirty years. They had shared interests that included science, social science, economics,epistemology, history of ideas and political philosophy. Studying their  correspondenceand related writings, this article shows that Hayek and Polanyi were committedLiberals but with different understandings of liberty, the forces that endanger liberty,and the policies required to rescue it.
