Title: Digital Neural Networks in Image and Video Analysis

Abstract:
Image and video analysis continues to present challenges to the research community. There is a challenge to extract the interesting information from a highly cluttered and variable background, and there is a challenge to extract this information over large data sets in a reasonable amount of time. Solutions must typically address both problems if they are to be successful.

In this talk, we will describe our recent efforts towards a joint solution, which we broadly call "digital neural networks". Digital Neural Networks, like other neural networks, are used to solve pattern recognition problems found in image and video analysis. However, unlike many other neural networks, Digital Neural Networks are designed with Field Programmable Gate Arrays (FPGAs) implementation in mind.

The combination can provide image and video analysis solutions with several orders of magnitude greater throughput than software solutions. The talk will be in three parts. First, we will introduce the growing field of morphological pattern recognition, and discuss implementation advantages and open research questions. Second, we will describe neural networks specific to image and video processing and detail our experiences with hardware / software implementation and acceleration. Finally, we will conclude the talk with some application examples where we solve a variety of recognition and tracking problems in video data.
