A mosaic method for large perspective distortion image

An image mosaic method focusing on images with large perspective distortion is proposed. Correction of perspective distortion based on perspective transformation model is applied first in this method to reduce the inconvenience of the distortion. To the corrected images, feature extraction, feature matching relied on the features in the overlapped area, and weighted fusion are applied to obtain a seamless mosaic image. The experimental result shows that this method is effective to the images with large perspective distortion.
