Abstract
Aerial photograph monitoring is used for evaluation of the eelgrass field. There is a problem with the method of extracting the eelgrass from RGB image by threshold method. Generally, this image analysis uses training data. This depends on the analytical accuracy and analysis time by the proficiency of the measurer. Therefore, in this research we use the snakes method used in the medical field. In this research, we tried applying this method to the aerial image of the eelgrass field.
As a result, it was confirmed that the eelgrass field can be extracted at a higher speed and accuracy of 80% than the conventional method.
