    marine analysis article front pageThis article, produced by Debora Levy and under the supervision of Dr. Tali Treibitz from the marine imaging lab of the marine biology department from the University of Haifa, with the help of Technion students and the Morris Kahn Marine Research Station top predator lab, is a big step towards the future of unmanned marine surveys and remote data collecting.

    Abstract:

    Monitoring of the marine environment requires large amounts of data, simply due to its vast size. Therefore, underwater autonomous vehicles and drones are increasingly deployed to acquire numerous photographs. However, ecological conclusions from them are lagging as the data requires expert annotation and thus realistically cannot be manually processed. This calls for developing automatic classification algorithms dedicated for this type of data. Current out-of-the-box solutions struggle to provide optimal results in these scenarios as the marine data is very different from everyday data. Images taken under water display low contrast levels and reduced visibility range thus making objects harder to localize and classify. Scale varies dramatically because of the complex 3 dimensionality of the scenes. In addition, the scarcity of labeled marine data prevents training these dedicated networks from scratch. In this work, we demonstrate how transfer learning can be utilized to achieve high quality results for both detection and classification in the marine environment. We also demonstrate tracking in videos that enables counting and measuring the organisms. We  emonstrate the suggested method on two very different marine datasets, an aerial dataset and an underwater one.
