摘要：
This paper presents an algorithm of image mosaic based on local features to improve the effect and speed of aerial image mosaic. The method registers images according to multi-resolution analysis and local features. The problem of image mosaic is turned into the problem of the coordinate transformation between the pixels by using affine transformation. The weighted average algorithm is used to achieve smooth stitching results and eliminate intensity seam globally. Experimental results show that the proposed method is effective for the mosaic of real aerial sequences and video images.
