WebMATLAB Functions for Multiple View Geometry. Functions include: Fundamental matrix and homography computation, gui's to visualize 2 view relations, and many others MATLAB … WebThe homography maps a coordinate on a plane into another one so you actually HAVE to apply it to every single pixel (x' ; y' ; 1) = H (x ; y ; 1) where H is your 3x3 homography matrix. Doing this you'll get the new image (plus some black areas), simply iterate the equation for every pixel in the image.
