how to change the histogram to the vector?

how to prove the histogram can be changed in the form of a vector?

Answer 1

[Image Analyst]

The histogram is normally already a vector of counts - the frequency of occurrence of values in your data. Nothing to convert - it's already a vector.

[counts values] = hist(data); % counts is a vector.

thank you. but, if the probability histogram is a vector? because I need to measure the similarity vector with one minus the correlation coefficient method.

[Walter Roberson]

What similarity vector is that?

Answer 2

[Walter Roberson]

You could create a histogram plot, and then go into the resulting barseries object and retrieve the YData from that object, and compare it to the original counts, and then use that retrieved set of counts to create a second histogram that will then look just like the first. The fact that the vector of data contains enough information to recreate the histogram plot will establish that the histogram can be converted to the vector.

thank you. I use vectors to calculate the similarity by using one minus the correlation coefficient of the two images with the histogram. is there any other solution of this problem?

[Image Analyst]

I'm not sure what that means. Do you have a formula for it?

[Dian Permatasari]

I create an image by using the identification method. steps are to change the image in the form of grayscale image and create a histogram, and then calculated the distance function method one minus correlation coefficient. (I have not made a formula of the distance function method). I need your help.

[Walter Roberson]

What part are you asking for assistance with?

[Dian Permatasari]

formula of one minus correlation coefficient method https://docs.google.com/document/d/1zvMfPp275GNoKWw7v6zNWAgkBQ1pqGyc2oHvoMom-1s/edit

[Dian Permatasari]

how the formula for calculating one minus correlation coefficient methods from histogram in matlab GUI?

[Image Analyst]

pBar = mean2(image1);
qBar = mean2(image2);

I think you can figure out the rest.

[Dian Permatasari]

thank you,, I tried to solve it.

[Walter Roberson]

In the formula you show, what is the dot operator, as in

(P-Pbar) . (Q-Qbar)

Is it the dot product?

[Dian Permatasari]

thank you.
