For the purposes of convolution, images can be thought of as functions on pairs of integers. The image has a given intensity value at each x and y coordinate; we can imagine, as we have been, that all values outside the boundaries of the image are zero. Although images are

of two inter-related real harmonic functions: u(x,y) = Re f(z) and v(x,y) = Im f(z). Before delving into the many remarkable properties of complex functions, let us look at some of the most basic examples. In each case, the reader can directly check that the harmonic functions provided by the real and imaginary parts of the complex function are

3.2. Real-valued functions We specialize to the case of real-valued functions f: X!R or extended real-valued functions f: X!R: We will consider one case or the other as convenient, and comment on any di er-ences. A positive extended real-valued function is a function f: X![0;1]: Note that we allow a positive function to take the value zero.

For 16-bit images, the image min and max are used for scaling instead of 255. Log For 8-bit images, applies the function f(p) = log(p) * 255/log(255) to each pixel (p) in the image or selection. For RGB images, this function is applied to all three color channels. For 16-bit images, the image min and max are used for scaling instead of 255.

the formula gives real number values in a small interval around x= a. For example 1 x a is not analytic at x= a, because it gives 1 at x= a; and p x ais not analytic at x= abecause for xslightly smaller than a, it gives the square root of a negative number. Taylor Series Theorem: Let f(x) be a function which is analytic at x= a.

### 2 Complex Functions and the Cauchy-Riemann Equations

Some of the most interesting examples come by using the algebraic op-erations of C. For example, a polynomial is an expression of the form P(z) = a nzn+ a n 1zn 1 + + a 0; where the a i are complex numbers, and it de nes a function in the usual way. It is easy to see that the real and imaginary parts of a polynomial P(z) are polynomials in xand

However, not all of these sets of numbers are elds of numbers. For example, 3 and 5 are in N, but 3 5 is not. Also, 3 and 5 are in Z, but 3=5 is not. This shows that N and Z are not elds of numbers. However, Q;R, and C are all elds of numbers. There are other (weird) examples of elds, but for this class you may assume that the word

### Injective and surjective functions

negative numbers aren t squares of real numbers. For example, the square root of 1 isn t a real number. However, like every function, this is sujective when we change Y to be the image of the map. In this case, f(x) = x2 can also be considered as a map from R to the set of non-negative real numbers, and it is then a surjective function. Thus,

Note that because the points are distinct, this determinant is not equal to zero. Because the determinant of coeﬃcient matrix of the linear system (1) is non-zero, that matrix is non-singular so that there exists a unique set of numbers a0, a1, a2, a3, , an−1, an that solve those linear systems. But those numbers are the
