Measuring fish length from digital images (FiLeDI)

In fishery research, fish length plays a great role to identify population. However, current method can be problematic as the fish should be obtained from the fishermen first. This process may lead to time consuming and cost overflowing. Therefore, a method to measure the length of a fish automatically using image processing and formula optic is greatly needed to solve these problems. In this paper, we will discuss on the details of FiLeDI framework. The FiLeDI framework is a combination between Hsiu's method and Serkan's method. The accuracy of measuring the fish length was 99.81%.
