A silhouette polygon matching method is proposed based on centroid distance in polar grid. With the polygon centroid as the origin, all the vertexes of the polygon in an image are converted into the polar coordinates. The polygon is partitioned into many grids according to the polar angle. The average centroid distance in each grid is considered as the(More)
When register a pair of remotely sensed images with very different spatial resolution, the diversity of their shape and tone results in lower precision and success rate. The paper proposes an algorithm of moveably resampled template match to fine register them, which resamples the high-resolution images to a sub-image by a movable mask plate, and then uses(More)
