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.

Using Matlab, plot the following ultrasound pressure wave as a function of x for t =1 P(t, x) = Poe** cos(@t – kx) where a = 0.15 neper/m, where neper is a dimensionless quantity, k = 1 rad/cm, o = 1 rad/s, and Po = 15 N/m2. Submit your ".m" file as well as the resulting graph labeled appropriately.
Given two control points A and B with known coordinates in both image and ground systems. Using the two dimensional similarity transformation, calculate the four parameters a, b, c and d. If X(A) = 678987.2 m; Y(A) = 7186939 m; x(A) = -5.076 mm; y(A) = 88.682 mm, and X(B) = 679059.4 m; Y(B) = 7187550 m; x(B) = 93.476 mm; y(B) = 81.863 mm.
An image has four possible gray levels, named r1, r2, r3, and ra. The probabilities of each gray level are: p(r1) = 0.066666666666667, p(r2) = 0.34666666666667, p(r3) = 0.42666666666667, and p(ra) = 0.16. If variable length coding is used to compress the image, the shortest code will be associated with which probability? Select one: O a. 0.8533 Ob. 0.0667 O. 0.4267 Od. 0.2133 Oe. 0.0333
