<Intensity Transformation: Histogram Specification>
An image with intensities in the range [0, 1] has the PDF,
pr(r), shown in Fig.1(a). It is desired to transform the intensity
levels of this image so that they will have the specified pz(z)
shown in Fig. 1(a). Assume continuous quantities and find the
transformation (expressed in terms of r and z: z = T(r)) that will
accomplish this.

Consider the following joint PDF of continuous random variables X and Y: 22 – 2pxy + y2 2(1 - 02) where pe(-1,1). (a) Prove that fx,y(x, y) is a joint PDF function. (b) What is the marginal PDF of X? (c) Calculate E[XY] – E[X]E[Y]. (d) Prove that X and Y are independent if and only if p= 0 (e) Show that the conditional PDF of X, given Y = y is N(py, 1 – p2.

1)If one measures the current in series resistors, is the current measured before the resistors different than what measured between the two resistors? a) no difference, current is the same b) the difference depends on the direction of the current c)the current after the first resistor will decrease d) yes, they are different If one measures the current in parallel resistors, are the currents in parallel resistors always the same? a) no, only currents in series resistors are the same...

Question 6 2 pts Fructose 1,6-P2 aldolase functions in both glycolysis and gluconeogenesis. Starting with DHAP in Schiff base linkage with the active site lysine of aldolase, show how that intermediate reacts with G 3-P to form fructose 1,6-P2 in Schiff base linkage at the active site. Use B: and HA as necessary. Make sure that you indicate mechanism with curly arrows, and draw each step out, but don't go all the way to the end of the reaction where...
