Start with what you have generated in Assignment #1 Q3 - Generate a 10 cm x 10 cm

"object" with 100 m x 100 m grid size. Randomly place 3 square objects somewhere in the

object, size 2 x 2 cm, with linear attenuation coefficients = 0.2, 0.5 and 0.1 cm-1

,

respectively (see the image below as an example). Assume that the background attenuation

is zero. Plot your object using the function 'imagesc'

. (5 points)

2. 3. Explicitly calculate the 1) original Beer's law projection, and 2) normalized log-projections

(as in Lecture 5, slide 16) for 0 and 90 degrees projections. (8 pts)

*Note - By "explicitly" I mean compute this in MATLAB using the formula directly (not the

radon function).
