how to store pixel location and color from impixelinfo

How can I retrieve data stored in the impixelinfo function.

I have used impixelinfo to display location and RGB colors of an image as well as the temperature of a grayscale image whenever the mouse hovers over a specific point the image. My issue is that I want to store the specific temperature and color value to a variable wherever the mouse hovers to be used for further analysis

How can I retrieve the impixelinfo being displayed and store it in a variable

William to get the values of the image under the path you've drawn you need to draw the path and record it's coordinates as you draw it. Then you can extract the values at those coordinates. I'm attaching a demo where you can use drawfreehand to do that.

this'll work appreciate it

What you describe is more Data Cursor http://matlab.izmiran.ru/help/techdoc/creating_plots/data_ex7.html

impixelinfo is more for extracting pixel information over a line. Internally, impixelinfo() determines whether the change in x coordinates is greater than the change in y coordinates, takes the longer of the two, and uses that as the independent variable for interp2 purposes.

When I right click on the image the only option that I get is to copy pixel info
