Vanishing points and vanishing lines are useful information in computer vision. In this study, an interesting dual property of vanishing point is "rst introduced. Next, we point out that there also exists a dual property of vanishing line. With the dual vanishing point and vanishing line properties, some 3D intersection inference can be made based on their image lines. Two applications are give...

We show that techniques inspired by Kollár and Viehweg’s study of weak positivity, combined with vanishing for log-canonical pairs, lead to new generation and vanishing results for direct images of pluricanonical bundles. We formulate the strongest such results as Fujita conjecture-type statements, which are then shown to govern a range of fundamental properties of direct images of pluricanonic...

Vanishing and Non-Vanishing Criteria for Branching Schubert Calculus by Kevin Purbhoo Doctor of Philosophy in Mathematics University of California at Berkeley Professor Allen Knutson, Chair We investigate several related vanishing problems in Schubert calculus. First we consider the multiplication problem. For any complex reductive Lie group G, many of the structure constants of the ordinary co...

We focus on the estimation of radial lens distortion utilizing vanishing points detected in single images. Recent methods for vanishing point detection either ignore radial distortion completely, or assume only weak distortion, which is accounted for after vanishing point estimation. Unfortunately, if strong radial distortion is present the effects are detrimental to the extraction of vanishing...

ewing sarcoma is about 10 % of bone tumours, in the form of lytic, sclerotic and mixed type. the lytic type erodes the whole bone in such a way that the auther would like to name it 'vanishing' type and recognition of this radiological type is of great importance from differential point of view in the study of primary and secondry tumours of bones.
