Barrett

Barrett, The Honors College at Arizona State University proudly showcases the work of undergraduate honors students by sharing this collection exclusively with the ASU community.

Barrett accepts high performing, academically engaged undergraduate students and works with them in collaboration with all of the other academic units at Arizona State University. All Barrett students complete a thesis or creative project which is an opportunity to explore an intellectual interest and produce an original piece of scholarly research. The thesis or creative project is supervised and defended in front of a faculty committee. Students are able to engage with professors who are nationally recognized in their fields and committed to working with honors students. Completing a Barrett thesis or creative project is an opportunity for undergraduate honors students to contribute to the ASU academic community in a meaningful way.

Thermal noise analysis of near-sensor image processing

Commonly, image processing is handled on a CPU that is connected to the image sensor by a wire. In these far-sensor processing architectures, there is energy loss associated with sending data across an interconnect from the sensor to the CPU. In an effort to increase energy efficiency, near-sensor processing architectures have been developed, in which the sensor and processor are stacked directly on top of each other. This reduces energy loss associated with sending data off-sensor. However, processing near the image sensor causes the sensor to heat up. Reports of thermal noise in near-sensor processing architectures motivated us to study how temperature affects image quality on a commercial image sensor and how thermal noise affects computer vision task accuracy. We analyzed image noise across nine different temperatures and three sensor configurations to determine how image noise responds to an increase in temperature. Ultimately, our team used this information, along with transient analysis of a stacked image sensor’s thermal behavior, to advise thermal management strategies that leverage the benefits of near-sensor processing and prevent accuracy loss at problematic temperatures.

Video playback is currently the primary method coaches and athletes use in sports training to give feedback on the athlete’s form and timing. Athletes will commonly record themselves using a phone or camera when practicing a sports movement, such as shooting a basketball, to then send to their coach for feedback on how to improve. In this work, we present Augmented Coach, an augmented reality tool for coaches to give spatiotemporal feedback through a 3-dimensional point cloud of the athlete. The system allows coaches to view a pre-recorded video of their athlete in point cloud form, and provides them with the proper tools in order to go frame by frame to both analyze the athlete’s form and correct it. The result is a fundamentally new concept of an interactive video player, where the coach can remotely view the athlete in a 3-dimensional form and create annotations to help improve their form. We then conduct a user study with subject matter experts to evaluate the usability and capabilities of our system. As indicated by the results, Augmented Coach successfully acts as a supplement to in-person coaching, since it allows coaches to break down the video recording in a 3-dimensional space and provide feedback spatiotemporally. The results also indicate that Augmented Coach can be a complete coaching solution in a remote setting. This technology will be extremely relevant in the future as coaches look for new ways to improve their feedback methods, especially in a remote setting.
