Vocal Processing With Spectral Analysis, Brad Fitzgerald
Vocal Processing With Spectral Analysis, Brad Fitzgerald
Scholar Week 2016 - present
A method of vocal signal processing was examined to determine if principal component analysis of spectral data may be used to characterize differences between speakers and if these differences may be used to separate mixtures of vocal signals. Processing was done on a set of voice recordings from 30 different speakers in order to create a projection matrix which could be used by an algorithm to identify the source of an unknown recording from one of the 30 speakers. Two different identification algorithms were tested, both of which were generally unable to correctly identify the source of a single vocal …
Weed And Crop Discrimination Through An Offline Computer Vision Algorithm, Phillip Jamison Putney
Weed And Crop Discrimination Through An Offline Computer Vision Algorithm, Phillip Jamison Putney
Scholar Week 2016 - present
With the recent global interest in organic farming and cultivation, many people are turning away from chemical-based herbicides and moving towards alternate methods to extirpate weeds living amongst their crops. Of the methods proposed, robotic weed detection and removal is the most promising because of its possibility to be completely autonomous. Several robust, fully-autonomous robots have been developed, although none have approved for commercial use. This paper proposes a weed and crop discrimination algorithm that utilizes an excessive green color filter paired with principal component analysis to detect spatial frequencies within an image corresponding to different types of weeds and …

The Olivet Nazarene University SAE Baja team designs a custom off-road vehicle every year to compete against teams from other schools at competitions throughout the year. The current car that the Baja team is working on needs some improvements, but they need some help gathering data to see where to make these improvements. In previous years, the Baja team would not have any feedback besides what they observed while driving, so this year they have tasked the SAE Baja Data Acquisition design group with the project of creating a sensor system and a data logging program to gather information that …
