Hi Sammy,

I'm not really sure what you are asking. Can you clarify what you mean - maybe give some examples?

I think all of us know what a histogram is.

What data are you attempting to plot in such a histogram?

Without more information you are on your own I'm afraid.

No, for at least a couple of reasons.

1) This site is NotACodeMill.(⇐click) You are expected to ShowSomeEffort.(⇐click)

2) There are many different possible interpretations of "histogram for a video", so you need to TellTheDetails(⇐click) about what exactly you're looking for, what exactly you tried, and what exactly you're having trouble with.

If you can follow those guidelines, there's a lot of great help to be found here. Good luck!

Of course.

If it is data it can be mapped.

How do you store the analysis? In memory (collections etc.) or in a database?

If you can mock it up in Excel (or openoffice.. whatever spreadsheet), then you can use Java to plot your histogram.


No one here is going to do your job for you.
We help those who are willing to learn.

It is a safe bet that most folks here know what a histogram is. We also know what still images and videos are.

What most folks here probably DON'T know is how you "use a histogram" on either a still image or a video image. I don't know how you "use a histogram" for anything. I know how to generate a histogram from data points. I know how to read a histogram. I've never done it, but I could probably figure out how to display one using java.

But I have no idea how to "compare (a video) using histogram".

A histogram is basically a graph. That means you need at least two variables. We have no idea if what you want is a histogram based on the color of each pixel, based on the number of dogs in the image, on the number of pixels that change from image to image...

You really need to tell us the details if you expect to get any real help. The best that I can tell, you are just stringing together random words and asking us to help you with that.
