Due date: 18 May 2011 Demosaicing (20 points)Here are two images represented with a Bayer pattern (View) and a modified Bayer pattern (View) that uses a white pixel instead of one of the green pixels. Write a command line program in Python to demosaic these images. Numerically compare the outputs of this program with the correct input image (View) (by differencing) and discuss.
Camera Geometry (20 points) Write
a command line Python program that takes as input a photo taken with a
camera held perfectly horizontally, as well as the height of the camera
over a flat ground and the focal length for a 35mm camera. The program
should write a distance scale into the center of the image, indicating
on the ground distance from the point of the ground where the
photographer was standing. This would write a distance scale for a picture taken at a height of 1.7m with a lens with a focal lenght of 50mm. |
