Question

I need help with 3 question in image processing.

1.visualize the function y (x) = sin (x) for interal 0-2pi. Knowing that the visualization in the computer graphic is displayed through the segments, please be careful in the steps to be given--i need matlab code
2.A set of indexed image colors is always of the class:

a)unit8 b)double c)unit16 d)logical

3.Considering the points P = [0,0] and Q = [24,10], show:
a) What is the shortest length between points P and Q in relation to neighborhood 4?
b) What is the shortest length between points P and Q in relation to the neighborhood 8?

Explanation / Answer

x = 0:pi/100:2*pi;
y = sin(x);

figure % opens new figure window
plot(x,y)

2A. uint8 (unsigned integer of 8 bits)

3.
P = 0,0
Q = 24,10

a
13 (sqrt((24/2)^2 + (10/2)^2))

b
7.8 (sqrt((24/4)^2 + (10/2)^2))
