Automatic stitching approach of aerial image sequence based on SIFT features
Hui Wang · Journal of Computer Applications · 2007
A new approach for automatic stitching of aerial image sequence was proposed,based on the SIFT(Scale Invariant Feature Transform)features.It consisted of two core steps:image registration and mosaic.The variations between two consecutive frames in aerial sequence are always very notable,thus the present commonly-used feature-based methods are not very suitable for their registration.Concerning this,an iterative registration method using the SIFT features was put forward.Moreover,for image mosaic,a new color fusion method was proposed to achieve smooth stitching results based on human visual features.Finally,experiments on real aerial sequences prove the effectiveness of the proposed stitching approach.
