A Physical Model Of Human Skin And Its Application For Search And Rescue, Abel S. Nunez Dec 2009

A Physical Model Of Human Skin And Its Application For Search And Rescue, Abel S. Nunez

Theses and Dissertations

For this research we created a human skin reflectance model in the VIS and NIR. We then modeled sensor output for an RGB sensor based on output from the skin reflectance model. The model was also used to create a skin detection algorithm and a skin pigmentation level (skin reflectance at 685nm) estimation algorithm. The average root mean square error across the VIS and NIR between the skin reflectance model and measured data was 2%. The skin reflectance model then allowed us to generate qualitatively accurate responses for an RGB sensor for different biological and lighting conditions. To test the …


Design Of Acousto-Optic Chaos Based Secure Free-Space Optical Communication Links, Anjan K. Ghosh, Pramode K. Verma, Samuel Cheng, Robert C. Huck, Monish Ranjan Chatterjee, Mohammed A. Al-Saedi Aug 2009

Design Of Acousto-Optic Chaos Based Secure Free-Space Optical Communication Links, Anjan K. Ghosh, Pramode K. Verma, Samuel Cheng, Robert C. Huck, Monish Ranjan Chatterjee, Mohammed A. Al-Saedi

Electrical and Computer Engineering Faculty Publications

We discuss the design of an acousto-optic cell based free space optical communication link where the data beam is made secure through chaos encryption. Using external signal modulation of the diffracted light from a hybrid acousto-optic cell chaos (or directly via incorporation in the sound-cell driver's bias voltage) encryption of data is possible. We have shown numerically that decryption of the encoded data is possible by using an identical acousto-optic system in the receiver.


Affine Region Tracking And Augmentation Using Mser And Adaptive Sift Model Generation, Matthew James Marano Jun 2009

Affine Region Tracking And Augmentation Using Mser And Adaptive Sift Model Generation, Matthew James Marano

Master's Theses

Relatively complex Augmented Reality (AR) algorithms are becoming widely available due to advancements in affordable mobile computer hardware. To take advantage of this a new method is developed for tracking 2D regions without a prior knowledge of an environment and without developing a computationally expensive world model. In the method of this paper, affinely invariant planar regions in a scene are found using the Maximally Stable Extremal Region (MSER) detector. A region is selected by the user to define a search space, and then the Scale Invariant Feature Transform (SIFT) is used to detect affine invariant keypoints in the region. …


Software Engineering Education At Carnegie Mellon University: One University; Programs Taught In Two Places, Ray Bareiss, Mel Rosso-Llopart Dec 2008

Software Engineering Education At Carnegie Mellon University: One University; Programs Taught In Two Places, Ray Bareiss, Mel Rosso-Llopart

Ray Bareiss

Teaching Software Engineering to professional master’s students is a challenging endeavor, and arguably for the past 20 years, Carnegie Mellon University has been quite successful. Although CMU teaches Software Engineering at sites world-wide and uses different pedagogies, the goal of the curriculum -- to produce world-class software engineers -- remains constant. This paper will discuss two of the most mature versions of Carnegie Mellon’s Software Engineering program -- the main campus program and its “daughter program” at the Silicon Valley Campus. We discuss the programs with respect to the dimensions of curriculum, how students work and learn, how faculty teach, …


Developing Software Engineering Leaders At Carnegie Mellon Silicon Valley, Ray Bareiss, Todd Sedano Dec 2008

Developing Software Engineering Leaders At Carnegie Mellon Silicon Valley, Ray Bareiss, Todd Sedano

Ray Bareiss

The Carnegie Mellon’s Silicon Valley Campus offers a master’s degree in Software Engineering, with technical and development management tracks, targeted at working software professionals in Silicon Valley. We believe the program to be unique in that it is entirely team-based and project-centered. Students learn by doing as they are coached just in time by faculty in the context of their work on authentic projects, and they are evaluated based on what they produce. In response to our interactions with an industry characterized by innovation and short project development timelines, the program evolved from one focused on “high ceremony” processes to …

Building A Business On Open Source Software, Tony Wasserman Dec 2008

Building A Business On Open Source Software, Tony Wasserman

Tony Wasserman

For many years, free and open source software was exclusively associated with the research community, in contrast to the closed source products developed by commercial software vendors. Over the past decade, there has been a vast increase in the availability of open source software, growing from such projects as Linux and Apache. Open source software is being widely adopted in industry, which has led to numerous business opportunities for entrepreneurs and vendors. This activity is having a disruptive effect on the software industry that has affected even the largest software vendors. This paper describes the emergence of open source business, …
