Scale-space behavior of corners is important for developing an efficient corner detection algorithm. In this paper, we analyze the scale-space behavior with the Laplacian of Gaussian (LoG) operator on a planar curve which constructs Laplacian Scale Space (LSS). The analytical expression of a Laplacian Scale-Space map (LSS map) is obtained, demonstrating the Laplacian Scale-Space behavior of the planar...
Crofton weed (Eupatorium adenophorum spreng) is an invasive species widely distributed in southwest of China. In this paper, we proposed a method for mapping the distribution of Crofton weed using time series remote sensing data. Because the reflectance signatures of the white flowers of Crofton weed are quite different from the other green components of plants, dissimilar index and flower index can...
