This is the same question just multiple parts.
Given our input photograph I (left in the figure below), we would like to "rectify" it to obtain a rectified square texture T (right). To do this, we need to know the homography that maps points (u, v) in the rectified texture to points (x, y) in the original image. .

(b) The equation of a line in the rectified texture is 1Tř= 0, where l is a vector of coefficients. The same line in the image is represented by the equation lT q = 0. Write down l' in terms of 1 and H. = =
