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 (...)

It's very easy to implement the color correlatation in matlab .............
you simply have to read the image in three different arrays R, G, B
Then either you use CONV2 or simply make a double for loop for Sum of Absolute difference calculation seperatly on each array..............

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

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 (...)

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.

I have an application in which i take the pictures from camera, then i want to compare that picture with my specified pattern/picture. I wana develop a code which recognize the camera picture/pattern.
I wrote the following code in matlab
I=imread('G:\pics_dsp\live\1.bmp')%read image from camera
rgb=rgb2gray(I)% convert (...)

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. :-(

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 (...)

correlation is an extremely simple task.Have you sorted out the camera and matlab interface?
I don't know about the kalman filtering part. I used sum of absolute differences to track motion.
First you'll have to acquire the image, identify the object using autocorrelation then, convert it into a logical (...)

I want to locate all the portions in an image that are of white color.... I just want to know that is there a function in matlab which takes input a level and returns us the value of pixels that contain values higher than that level. If there is any other way to do this please let me know.....
