Anderson and James K. Archibald Electrical and Computer Engineering Department Brigham Young University Provo UT 84602 USA Correspondence should be addressed to Dah-Jye Lee djlee@ Received 30 November 2007 Accepted 25 February 2008 Recommended by . Chung Many image and signal processing techniques have been applied to medical and health care applications in recent years. In this paper we present a robust signal processing approach that can be used to solve the correspondence problem for an embedded stereo vision sensor to provide real-time visual guidance to the visually impaired. This approach is based on our new one-dimensional 1D spline-based genetic algorithm to match signals. The algorithm processes image data lines as 1D signals to generate a dense disparity map from which 3D information can be extracted. With recent advances in electronics technology this 1D signal matching technique can be implemented and executed in parallel in hardware such as field-programmable gate arrays FPGAs to provide real-time feedback about the environment to the user. In order to complement not replace traditional aids for the visually impaired such as canes and Seeing Eyes dogs vision systems that provide guidance to the visually impaired must be affordable easy to use compact and free from attributes that are awkward or embarrassing to the user. Seeing Eye Glasses an embedded stereo vision system utilizing our new algorithm meets all these requirements. Copyright 2008 Dah-Jye Lee et al.
