Abstract
Considering automatic approaches of road extraction have two difficulties: the first one is how to identify initial tracking position and direction automatically, and the second one is how to complete the tracking process correctly with the disturbing influence, we proposed a new method of automatic road extraction from high-resolution remote sensing image based on bat model and mutual information matching. Firstly, for determining the initial tracking position and tracking direction automatically, we proposed a fully new model, which was called bat model. It included the following aspects: region seed detection based on improved Harris detector and road seed extraction based on fully new bat algorithm. By taking into account the context features of candidate road seeds, the bat algorithm simulated bat behavior to search all forward paths from current position and determine the best moving direction. Secondly, for road tracking, we designed a new method to get initial reference template automatically and proposed road tracking based on mutual information matching. According to the experiment results, the proposed method can determine initial tracking position correctly, and complete the tracking process automatically even if the road represents a shape of ribbon with a big bending and the disturbing influence.
