With the aim of achieving a correlation, I need to create two images of size
256 * 256, which contains a letter F and serve as a target, while the other has two letters E and F showing the scene .
I'm stuck in, how to center the letter F in the middle of the image, and how, after correlation, display (...)

Every time I get an image, I need to compare it with a lot of existing images and take an appropriate decision. But, the 'elseif' statement makes it very slow. But I cant use switch case because the switch expression needs to be a scalar or string. How can I do my comparison in a faster way?
Please help. :-(

I want to match a test image with the template image in matlab, For this task i am using normxcorr2 function for correlation, this function returns an array of correlation between template and test image.
This function works fine when template image is a (...)

Template is the pattern you want to find in the image. For example if you are looking for circles in an image, a smaller image containing only a circle is the template. Once you calculate the cross-correlation between a template T and an image I, you obtain an image X.

Hi, I am a third year mechanical engineering student and have been assigned to design matching algorithm based on image "correlation" using matlab. I am free to research and inspire myself from any source code I can find, as I will be awarded with marks for research. The problem is I must use the matlab function (...)

To generate a Rayleigh fading channel model, you first generate real and image part of the independent Gaussian process, then you need design a filter to have the spretrum similar to Jakes model, i.e, to have the Bessel function as the auto-correlation. Passing through the I, Q Gaussian process to this filter, you oculd get the Rayleigh fadung mode
