由海洋模式数据和卫星高度计诊断的海表面高度诊断海洋中尺度涡旋的matlab程序(Detect the geostrophic eddies altimetry and ocean models sea surface height (SSH). Detection method : a combination of detecting the largest closed contours in SSH and the positive values of an Okubo-Weiss parameter. This require less tunable parameters in comparison to previous methods. This is usefull for the comparisons between different products, such as models and altimetry.)

主要讨论获得图片后如何提取其边界信息,首先利用图像灰度均匀化解决了对比度不清晰的问题,然后利用高斯滤波法对图片进行滤波去噪,进而利用Canny算法实现边缘检测提取边界,该方法与Matlab自带的求边界方法有明显的提高,为利用Matlab程序求图像分形维数提供了更精确的前提. 更多还原 (Mainly discuss how to get the picture after extracting its boundary information, the first use of the image contrast of the gray uniform solution to the problem is not clear, then use a Gaussian filtering method for image filtering noise, and then use Canny edge detection algorithm to extract the boundary, the method find boundary method comes with Matlab significantly improved procedures for the use of Matlab for image fractal dimension provides a more accurate premise. more reduction)
