Abstract
We present a fish detection method capable of detecting fish profiles in underwater video while filtering out complicated unwanted images such as fish tails, otters, juvenile fish and turbulent water. Also, fish attributes, such as size and orientation, are automatically displayed as fish are detected. This method utilizes the Hough transform to automatically detect fish profiles. We display the results of this method applied to images from Freshwater Creek and discuss benefits from using the Hough transform to detect fish. We also discuss strengths of the method along with future applications, including the possibility of implementing a real-time detection scheme based on this method.
