Weborb: [noun] any of the concentric spheres in old astronomy surrounding the earth and carrying the celestial bodies in their revolutions. WebMar 8, 2024 · Homography Computation After computing the pairs of matching features of the input images, it is possible to compute the homography matrix. It takes as input the matching points on each image and using RANSAC (random sample consensus) we are able to efficiently compute the projective matrix. WebJan 8, 2013 · In short, we found locations of some parts of an object in another cluttered image. This information is sufficient to find the object exactly on the trainImage. For that, we can use a function from calib3d module, ie cv.findHomography (). If we pass the set of points from both the images, it will find the perspective transformation of that object. how to seal alcohol ink art
