Locally Connected Adaptive Gabor Filter for Real Time Motion Compensation

摘要

The purpose of this study is to investigate and to develop locally connecteddynamic Gabor filter for real time illumination-invariant motion compensation. This work can be employed in various applications, including potential applications in image stabilization. In particular, this research project consists of the phase of theoretical study, algorithm development, and VLSI (very Large Scale Implementation) chip design. The chip design process begins with the system level design which first translates the mathematical formulation to hardware requirement and specifications, then the subsystem level, and basic building block designs are performed together with circuits simulations prior to the physical VLSI circuits layout. Then the designed chip, Gabor filter, is submitted to MOSIS for fabrication on double poly 2.0 micro CMOS technology. In order to verify the mathematical formulation, software simulation in C programming language is first performed. The source code is documented and submitted to ONR as one of the progress reports, in addition an user manual is also submitted to ONR for reference purpose. The VLSI Gabor chip is fabricated, then the post-fabrication testing and verification are conducted. The electronics characteristics are measured against the designed specification, silicon modifications are made, bugs are removed. A functional, working chips are obtained.
