B) For an image f(x,y) of size M (rows)* N (columns), if the number of discrete intensity levels L is 16, m=640, and N-712, find the size of the image in byte. Hint. 1-2 where K is the number of bits representing one pixel. If the spatial resolution of this image is 220 dot per inches( dpi) find the actual size of the image in inches for both height and width.

Please note that neither the center of projection nor the projection plane is at the origin. So please use the appropriate general perspective projection matrix to solve this problem. I have attached an image of the projection matrix that you have to use where Qdx is the x coordinate of the center of projection, Qdy is the y coordinate of the center of projection, and zp is the z coordinate of the center of the projection plane. Let a 3D point (423, -423, 423) be projected on a projection plane. Given that the center of the projection plane is (0.0, 0.0, -423.0) and the coordinate of the COP is (4, 2, 3). Determine the coordinate of that 3D point on the projection plane using a general purpose perspective projection matrix.

7. Plot the function f) = for-4 sx<3. Notice that the function has a 0.8(x+1) vertical asymptote at x=-1. Plot the function by creating two vectors for the domain of x. The first vector (name it xl) includes elements from 4 to-1.1. and the second vector (name it x2) includes elements from-0.9 to 3. For each x vector create a y vector (mane them yl and y2) with the corresponding values of y according to the function. To plot the function make two curves in the same plot (yl vs. xl, and y2 vs. x2)
