i installed a darvi camera and taken the thermal images from this camera. i get the image in jeeg format. i want to calculate the tempratue of eache pixel of that image, i want ta calculate emistivity, region of interset. is it possible in matlab

See attached demo. I had been using hard coded coordinates for the colorbar since, once known, they won't change for that particular camera. However so many people seem to be unable to figure out what coordinates the image and color bar are at that I decided to have the user draw a box around each. I also adapted it to handle either vertical or horizontal colorbars.

@Neha Thakkar that's what the temperature image, "thermalImage", is. Just mouse around over the image and see the temperature at the bottom of the GUI. Or you can double click thermalImage in the workspace to have it popup in a spreadsheet like form inside MATLAB. If that solves it, can you click the "Accept this answer" link? Thanks in advance. 🙂

That won't because it's not using my program. It looks like you're just using some interactive MATLAB function to read in an RGB image. You need to do it from my program. You can either watch the GUI as you mouse around or specify a list of (row, column) coordinates to thermalImage array in the code.
