Research of keeping key point algorithm in vector compression
Zhang Haoli · Computer Engineering and Applications Journal · 2015
In the compression of vector data, the commonly used methods may make the position of some key points relative to the closed region changed. In the application of petroleum exploration vector, these key points are usually the position of wells. So this factor would result in the wrong geological interpretation. This paper presents a method to keep the key points to improve the compression algorithm for finding out the change of the relative position of the key points, and then determine the compression zone where causes the variation, with certain rules to add or eliminate these anomalies.This method solves the practical problems in the application.
