compare pixel values to each other? Is ther afunction in Matlab that can analyze the composition of an image as a function of distance?

I am interested in looking at how the image changes over a distance within the image, any recommendations?

It’s not a cell it’s just an example because I’m still trying to identify the image but yes if it’s a cell I want to know the size area and density of the cells in one region and how they change over the length of the image.

If you have any more questions, then attach your image and code to read it in with the paperclip icon after you read this:
And somehow indicate, in a separate image, the things in the image you'd like to use in computations.

That pretty much explains the basics. You can probably adapt it to your particular image.

No, drawpoints is for situations where you need to indicate single points/pixels on an image. drawrectangle and drawpolygon are for when you need to draw 2-D regions.

The answer to your question is NO, there is no MATLAB function to analyze the composition of an image as a function of distance.

Yes I think that would be helpful. Just to be safe how would I perform background substraction and also masking to get rid of other specs in the image that I might not be interested in for the future.

See attached seminar on background correction, color correction, and color calibration. I've just updated some slides from what I've posted in the past years..
