Edge Detection in Remote Sensing Image Based on the Advanced Snake Algorithm

摘要

The paper takes an advanced snake algorithm to make research on the edge detection in order to improve the automatic analysis of the computer and select the objects interested in the remote sensing image. Edge detection by the algorithm is the process of image gradient characteristic, continuity, flatness, and shape information constrained into an energy function. We can achieve the goal of objective selection by calculation the minimum of the energy function. In the water quality monitoring of the Yalu River, the effectiveness of the proposed method and its value of practicality can be confirmed.
