I'm a little unclear about what exactly you're trying to do, but what I think you want is to select a region of interest, then c...
I'm working with intensity maps, so BW images. The values in one set of images are 8-bit integers in one, and double precision ...

Triangle numbers are the sums of successive integers. So 6 is a triangle number because
6 = 1 + 2 + 3
which can be displa...

Given an input vector x, find all elements of x less than 0 or greater than 10 and replace them with NaN.
Remove the nth column from input matrix A and return the resulting matrix in output B.
A = [1 2 3; 4 5 6];
Write a function which returns every other element of the vector passed in. That is, it returns the all odd-numbered elements, s...
Given a and b, return the sum a+b in c.
Given the input n, return true if n is odd or false if n is even.
Find the sum of all the numbers of the input vector x.
Input x = [1 2 3 5]
Output y is 11
Input x ...
In MATLAB, you create a vector by enclosing the elements in square brackets like so:
x = [1 2 3 4]
Commas are optional, s...
Try out this test problem first.
Given the variable x as your input, multiply it by two and put the result in y.
Since RGB images are really 3D matrices, you can use the squeeze command :
pixelRGB = squeeze(yourImage(x,y,:));
You could set up your problem in a couple of ways. The easiest would be by brute force using nested loops, though it may not be...
The entropy is calculated from the histogram of the image, so if you have the same pixel values, it doesn't matter if you shuffl...
Have you tried IMWRITE? Depending on the format you want to save as, you can specify the resolution in the command. You have t...
