MATLAB: Mapping of temperature values on ROI of image

computer visionduplicate postimage processingthermal image

I had to find the required temperature values from my ROI in a thermal video. I extracted some frames and extracted the region of interested that is still in the form of pixels. Now I want to map temperature values to that ROI from my excel file that is basically extracted from the same frame. After that I have to test whether the values are exactly from the region of interest or not? Any idea about that or any example. Waiting for you kind response. Thanks

There are only two regions: the region(s) you're interested in, and the region(s) you're not interested in. If you want to mask out the region that is the region you're not interested in, then complement the mask of the ROI. So for example to mask out (set to zero) the region outside the region of interest, you'd do this:

grayImage(~roiMask) = 0;
