METHOD AND APPARATUS FOR MULTI-BAND BLENDING OF A SEAM IN AN IMAGE DERIVED FROM MULTIPLE CAMERAS

摘要

A method, apparatus and computer program product are provided to combine images captured by multiple cameras into a panoramic image, such as a 360° panorama, in a manner that reduces image defects and other artifacts at or near a seam between images. In some implementations of example embodiments, the overlapping portions of two images are decomposed into a predetermined number of bands. For most of the bands, a laplacian of Gaussian blending mask is applied when blending images associated with the relevant bands. For a final band, a linear blending mask is applied, and the bands are combined into an image that may be used in connection with a panoramic image featuring portions of multiple images captured by an array of cameras. In some example implementations, a bandwidth for the final band may be determined based in part on a selected sharpness factor.
