    Intel@Technion Lectures: On the Way to Visual Understanding

    Speaker:
    Gershom Kutliroff (Intel)
    Date:
    Wednesday, 10.2.2016, 11:30
    Place:
    Room 337-8 Taub Bld.

    n the past several years, the field of computer vision has chalked up significant achievements, fueled by new algorithms (such as deep neural networks), new hardware (such as consumer 3D cameras) and new available processing (such as GPU’s). When we consider the problems that tomorrow’s household robots and autonomous vehicles will have to solve, however, there is evidently still a ways to go. In this talk, I will discuss current work within Intel’s Perceptual Computing on a scene understanding pipeline, based on 3D camera data. The aim of this work is to enable a far deeper understanding of an environment than existing techniques currently provide

    Short bio:
    Dr. Gershom Kutliroff. Over the last 20 years, Gershom has held multiple positions in the computer vision and graphics industries, leading R&D efforts in the areas of human-computer interaction and visual understanding, and is an inventor on over 20 patents and patents pending. He was the CTO and co-founder of Omek Interactive, which developed hand tracking and gesture control technology, and was acquired by Intel in 2013. Dr. Kutliroff continues to pursue his interest in computer vision as a Principal Engineer within Intel’s Perceptual Computing group. He earned his Ph. D. and M. Sc. in Applied Mathematics from Brown University, and his B. Sc. in Applied Mathematics from Columbia University. Dr. Kutliroff is married with five children, but he still holds out hope to one day hike the Appalachian Trail

    Title: Efficient Voronoi Diagram Construction for Planar Freeform Spiral Curves


    Abstract:
    We present a real-time algorithm for computing the Voronoi diagram of planar freeform piecewise-spiral curves. The efficiency and robustness of our algorithm is based on a simple topological structure of Voronoi cells for spirals. Using a Möbius transformation, we provide an efficient search for maximal disks. The correct topology of Voronoi diagram is computed by sampling maximal disks systematically, which entails subdividing spirals until each belongs to a pair/triple of spirals under a certain matching condition. The matching pairs and triples serve as the basic building blocks for bisectors and bifurcations, and their connectivity implies the Voronoi structure. We demonstrate a real-time performance of our algorithm using experimental results including the medial axis computation for planar regions under deformation with non-trivial self-intersections and the Voronoi diagram construction for disconnected planar freeform curves.

    This is a joint work with Jaewook Lee, Yong-Jun Kim, and Gershon Elber.

    Speaker: Dr. Jinesh Machchhar (Computer Science, Technion)
    Title: Revisiting the Problem of Zeros of Univariate Scalar Beziers


    Abstract:
    This work proposes a fast algorithm for computing the real roots of univariate polynomials given in the Bernstein basis. Traditionally, the polynomial is subdivided until a root can be isolated. In contrast, herein we aim to find a root only to subdivide the polynomial at the root. This subdivision based algorithm exploits the property that the Bezier curves interpolate the end-points of their control polygons. Upon subdivision at the root, both resulting curves contain the root at one of their end-points, and hence contain a vanishing coefficient that is factored out. The algorithm then recurses on the new sub-curves, now of lower degree, yielding a computational efficiency. In addition, the proposed algorithm has the ability to efficiently count the multiplicities of the roots. Comparison of running times against the state-of-the-art on thousands of polynomials shows an improvement of about an order-of-magnitude.

    This is a joint work with Gershon Elber.

    Title: Getting mixed-integer parametrization to the end user: a progress report


    Abstract:
    In recent years scientific results on parametrization and remeshing have evolved quickly, with new and improved techniques being presented every couple of months. This talk will present an overview of the speaker’s work on taking a tool based on mixed-integer quadrangulation from a scientific project to a product ready for use by designers and other end-users - and the constant struggle between being outdated from day one and never finishing at all.
