1. 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 P N corresponding to the frame N and an image Q N corresponding to the frame N, wherein the spatial distortion is calculated based on luminance and chrominance value for each pixel in the region of overlap; calculating a temporal distortion Temporal(i,j) for each pixel in said region of overlap by sub-sampling the frame and calculating a median pixel value over the region of overlap and then checking a number of times it deviates above a threshold level; 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 P N and Q N together to form a composite image C N .
