Coastal discharge plume is one of the most important pollution hazards for the heavily polluted estuaries in Shenzhen, China. Due to their dynamic and episodic nature, these pollutions are difficult to sample adequately using traditional in situ measurement methods. This paper introduces a plume extraction method using fully polarimetric synthetic aperture radar (SAR) image. TerraSAR data acquired...
The energy moments based on Discrete Cosine Transform are presented as an efficient feature descriptor. Based on this, a new approach for image retrieval using integrated annular color moments and energy moments features is proposed. The experimental results show that the proposed method is not only very robust in terms of scale and rotation invariance but also efficient.
