Suppose you are given an image of stellar events which are simply three bright dots or points in different locations in the spatial domain. Your task is to measure the brightness of each point but unfortunately the imaging system being used has an intensity distorting effect that yields a constant multiplicative effect, K, on the image in the spatial domain. That is, faistorted (x, y) = K x original image a) Provide a simple model for fäiztorted(x,y) assuming ideal points each with a given intensity, A1, A2 and As located at (x1, y1). (x2,Y2), and (x3, Y3), respectively. b) Give an enhancement process similar to homomorphic filtering to give you the best chance of accurately measuring the brightness of the points i.e. estimating A1, A2 and As.

Consider a room with world coordinate system U-V-W as shown. Two cameras are mounted in the room, forming a stereo pair. The world coordinate origin is in one corner of the room, with UV-W axes shown. The "Left" camera Cl is located at world coordinates (10,1,3) and it's xl-yl-zl axes are oriented as shown. The "Right" camera Cr is located at world coordinates (7.1,2) and its xr-yr-zr axes are oriented as shown. Both cameras have a focal length of 1. U (1) What is the 3x4 matrix that maps 3D points in world coordinates into 2D points in film plane coordinates (when points are represented as homogeneous coordinates), for the left camera CI? (2) What is the 3x3 essential matrix for the two cameras, treating them as a stereo pair where Cl is the "left camera" and Cr is the "right" camera?
