    1) Based off of the image, I can tell that ship #1 seems to be a carrier of weapons and soldiers alike. Ship # 2 looks like a runway for the aircrafts and the operators of said aircrafts. The carrier is 315 m long while the other ship is slighter longer by estimation. It can be assumed to be as long as 400 m long.

    2) The way you can tell a road or rail line was intended for missile transport is by the association of the rail lines’ with the air ships in the image. This Spatial relationship between these objects states their cultural context.

    3) If the Variance = 5106.4, Then the Standard deviation is:

    Standard deviation(σ)=√Variance=√5106.4=71.45

    The estimated distance between the background and target is 70 σ.

    4) The dynamic ranges I would use to display the scene and enhance each region of interest would be 65-1050.

    5) >> A = [40 20 30 15; 50 25 30 16; 60 28 30 14];
    >> C= cov(A)

    C =

    100.0000 40.0000 0 -5.0000
    40.0000 16.3333 0 -1.5000
    0 0 0 0
    -5.0000 -1.5000 0 1.0000

    c= corr(A)

    c =

    1.0000 0.9897 NaN -0.5000
    0.9897 1.0000 NaN -0.3712
    NaN
    -0.5000 -0.3712 NaN 1.0000
