Abstract
In one embodiment, there is provided a method for stitching left images P from a first imager with right images Q from a second imager thereby to produce stitched video images, the method comprising: for each current frame N: calculating a spatial distortion Spatial(i,j) for each pixel in a region of overlap between an image PN corresponding to the frame N and an image QN corresponding to the frame N; calculating a temporal distortion Temporal(i,j) for each pixel in said region of overlap; determining a minimal cost path for traversing the region of overlap from top to bottom, wherein said minimal cost path comprises a pixel from each row in said region of overlap; and setting said minimal cost path as a seam for stitching images PN and QN together to form a composite image CN.
