Smart vision systems that capture data in both private and public environments are now ubiquitous and have applications in security, disaster response, robotics, and smart environments, among others. Processing this data manually is an immensely tedious - and for some applications - an infeasible task, and an enhanced level of automation and self-awareness in the overall system is a key to overcome the design challenges. This special session addresses design aspects of smart vision systems realized at different levels: the image sensor, the camera node and the system level.

| 14:00 | 11.1.1 | THE CAMEL APPROACH TO STACKED SENSOR SMART CAMERAS Speaker: Marilyn Wolf, Georgia Institute of Technology, US Authors: Saibal Mukhopadhyay1, Marilyn Wolf1 and Evan Gebahrdt2 1Georgia Institute of Technology, US; 2School of ECE, Georgia Institute of Technology, US Abstract Stacked image sensor systems combine an image sensor, memory, and processors using 3D technology. Stacking camera components that have traditionally been packaged separately provides several benefits: very high bandwidth out of the image sensor, allowing for higher frame rates; very low latency, providing opportunities for image processing and computer vision algorithms which can adapt at very high rates; and lower power consumption. This paper will describe the characteristics of stacked image sensor systems and novel algorithmic and systems concepts that are made possible by these stacked sensors.

| 14:18 | 11.1.2 | A DESIGN TOOL FOR HIGH PERFORMANCE IMAGE PROCESSING ON MULTICORE PLATFORMS Speaker: Shuvra Bhattacharyya, University of Maryland, College Park, MD, USA and Tampere University of Technology, Finland, US Authors: Jiahao Wu1, Timothy Blattner2, Walid Keyrouz2 and Shuvra S. Bhattacharyya1 1University of Maryland, US; 2National Institute of Standards and Technology, US Abstract Design and implementation of smart vision systems often involve the mapping of complex image processing algorithms into efficient, real-time implementations on multicore platforms. In this paper, we describe a novel design tool that is developed to address this important challenge. A key component of the tool is a new approach to hierarchical dataflow scheduling that integrates a global scheduler and multiple local schedulers. The local schedulers are lightweight modules that work independently. The global scheduler interacts with the local schedulers to optimize overall memory usage and execution time. The proposed design tool is demonstrated through a case study involving an image stitching application for large scale microscopy images.

| 14:36 | 11.1.3 | QUASAR, A HIGH-LEVEL PROGRAMMING LANGUAGE AND DEVELOPMENT ENVIRONMENT FOR DESIGNING SMART VISION SYSTEMS ON EMBEDDED PLATFORMS Speaker: Bart Goossens, Ghent University - imec, BE Authors: Bart Goossens, Hiêp Luong, Jan Aelterman and Wilfried Philips, Ghent University, Dept. of Telecommunications and Information Processing, BE Abstract We present Quasar, a new programming framework that handles many complex aspects in the design of smart vision systems on embedded platforms, such as parallelization, data flow management, scheduling and load balancing. Quasar, as a highlevel programming language, is nearly hardware-agnostic, has a low barrier of entry and is therefore well suited for algorithm design and rapid prototyping. Through several benchmarks and application use cases we demonstrate that programs written in Quasar have a performance that is on a par with (or better than) hand-tuned CUDA and OpenACC code while the development requires much less time and is future-proof.

| 14:54 | 11.1.4 | CONCURRENT FOCAL-PLANE GENERATION OF COMPRESSED SAMPLES FROM TIME-ENCODED PIXEL VALUES Speaker: Ricardo Carmona-Galan, Instituto de Microelectronica de Sevilla (CSIC-Univ. de Sevilla), ES Authors: Marco Trevisi1, Héctor C Bandala2, Jorge Fernández-Berni1, Ricardo Carmona-Galán1 and Ángel Rodríguez-Vázquez1 1Instituto de Microelectrónica de Sevilla (IMSE-CNM), CSIC-Universidad de Sevilla, ES; 2Dept. Electronics, Instituto Nacional de Astrofísica, Óptica y Electrónica (INAOE), MX Abstract Compressive sampling allows wrapping the relevant content of an image in a reduced set of data. It exploits the sparsity of natural images. This principle can be employed to deliver images over a network under a restricted data rate and still receive enough meaningful information. An efficient implementation of this principle lies in the generation of the compressed samples right at the imager. Otherwise, i. e. digitizing the complete image and then composing the compressed samples in the digital plane, the required memory and processing resources can seriously compromise the budget of an autonomous camera node. In this paper we present the design of a pixel architecture that encodes light intensity into time, followed by a global strategy to pseudo-randomly combine pixel values and generate, on-chip and on-line, the compressed samples.

| 15:12 | 11.1.5 | CONTACTLESS FINGER AND FACE CAPTURING ON A SECURE HANDHELD EMBEDDED DEVICE Speaker: Axel Weissenfeld, AIT Austrian Institute of Technology GmbHA, AT Authors: Axel Weissenfeld and Bernhard Strobl, Austrian Institute of Technology, AT Abstract Traveler flows and crossings at the external borders of the EU are increasing and are expected to increase even more in the future; trends which encompass great challenges for travelers, border guards and the border infrastructure. In this paper we present a new handheld device, which enables border control authorities to check European, visa-holding and frequent third country travelers in a comfortable, fast and secure way. The mobile solution incorporates new multimodal biometric capturing and matching units for face and 4-finger authentication. Thereby, the focus is on the capturing unit and fingerprint verification, which is evaluated in detail. On the other hand, the use in border control requires high security measurements and trustworthy use of credentials, which are also presented. Tests of the handheld device at a land border indicate great acceptance by travelers and border guards. Download Paper (PDF; Only available from the DATE venue WiFi) |
