Abstract: A video splicing method includes: acquiring a first video and a second video, which are to be spliced, wherein the first video is before the second video; performing freeze frame detection on the first video or the second video, so as to obtain a freeze frame sequence; obtaining a reference video frame on the basis of the freeze frame sequence; searching for an overlapping area on the basis of the reference video frame, so as to obtain a first overlapping video frame area corresponding to the first video and a second overlapping video frame area corresponding to the second video; and on the basis of the first overlapping video frame area and the second overlapping video frame area, splicing the first video and the second video to obtain a spliced video. By means of the method, the video splicing effect can be improved.

Abstract: Provided are an image fusion method and apparatus, and a portable terminal. The method comprises: obtaining several aligned images; respectively calculating gradient information of each image; setting a mask image of each image, and generating a target gradient image; performing a gradient operation on the target gradient image, and obtaining a target Laplacian image; performing a deconvolution transform on the Laplacian image, and generating a fused panoramic image. The technical solution generates a Laplacian image by performing gradient information calculations on several images, and then performs a deconvolution transform to generate a fused panoramic image, thereby eliminating image stitching color differences, and implementing a better image fusion effect.
