Quantification of Individual Underwater Objects |
|
Dreissenid mussels have, in the past twenty years, invaded much of the Great Lakes bottom surface area. In past years, several statistical methods have been employed to map and estimate the total number of mussels in the lakes. This project tests the viability of using a continuous underwater video feed, coupled with a MATLAB image processing algorithm, to count individual objects (coins) underwater on a flat bottom surface. While the process was effective for an unstacked, spread coin distribution, several improvements must be made before implementation in field research. |
