Incremental Tree Induction for Detection of the Rescue Target in the Marine Casualty

In the case that a marine casualty occurs, the detection of the rescue target such as life rafts is surely required to carry out the prompt rescue of human life.To detect the small target in the wide views over the sea, we have proposed a new method including the feature extraction techniques based on the color information and the system learning method based on incremental tree induction. The color information derived from the image data is used to construct the incremental tree which can update online to adapt well to the real time circumstance. The experimental results show that the proposed method is efficient to detect the small target in cluttered natural scene.
