Measurement of Pack Ice Area and Concentration using Image Processing Package

Due to the increasing possibility of passing the Arctic route, considerable works on the icebreaking vessels have been continuously published. The model ship test on the pack ice model in the ice tank is actively carried out as a way to investigate the performance of icebreaking vessels. The concentration as well as the individual area of pack ice are important since they directly affect the performance. However, it is not easy to obtain those properties because not only the pack ice has uneven shape but also it keeps floating around in the ice tank. In this paper, an algorithm to identify the concentration of pack ice is introduced. From a digital image of pack ice obtained in the ice tank, the goal is to measure the area of pack ice using an image processing technique. Instead of the general global thresholding that yields numerical errors in this problem, a local thresholding technique, coupled with image subdivision based on the quadtree structure, is developed. The individual area of each ice patch is calculated using the edge extraction and the watershed technique.
