Multifractal filtering method for extraction of ocean from remotely sensed imagery

Traditional methods of extracting the ocean wave eddy information from remotely sensed imagery mainly use the edge detection technology such as Canny and Hough operators. However, due to the complexities of ocean eddies and image itself, it is sometimes difficult to successfully detect ocean eddies using these methods. A mnltifractal filtering technology is proposed for extraction of ocean eddies and demonstrated using NASA MODIS, SeaWiFS and NOAA satellite data set in the typical area, such as ocean west boundary current. Results showed that the new method has a superior performance over the traditional methods.

花粉：海洋沉积物中有机物氧化作用的指示物

花粉：海洋沉积物中有机物氧化作用的指示物ＲｉｃｈａｒｄＧ．Ｋｅｉｌ等控制海洋沉积物记录中有机物保存的因素仍然是激烈争议的话题。许多调节因素互相牵连，使同时过程间的辨别变得困难。海洋沉积物中低于５０％的有机物质可以以分子方式辨别，一般来说少于１０％被保...
