How can we re construct images with equation for temperature distribution. ?

I have the thermal images for one side of the glass and an equation of temperature distribution on the other side . how can construct thermal images on the other side from the images avilable now and the equation. T_other side = -0.25807*T_availble_side+ 53.3947

Thanks in advance

How can i change the linear eqaution to a polynomial equation of second ordder or more and also similar change by using exponential equation

Once you have your temperature image (not pseudocolored image), you can do whatever math on it that you want.

Not able to use the polynomial functin ?

[Image Analyst]

I don't understand what you're asking. Are you asking me if I am not able to use a polynomial function? Well, yes of course I know how to use a polynomial function. Who doesn't? It's rather straightforward. And no one is preventing me from using a polynomial function whenever I want to.

If that's not what you meant, then please explain using complete sentences that are very explicit so there is no doubt of ambiguity about what you mean.

I have the thermal images for one side of the glass and an equation of temperature distribution on the other side . how can construct thermal images on the other side from the images avilable now and the equation. T_other side = (-0.1816)+1.32947*(T_availble_side)- 0.00974 (T_availble_side)^2

See my attached demo.

[JINU SUDHAKARAN Mr]

can you please explain the method. The image you attached is corresponding to the first image. is it?

how can we use the eautaion for conctructing the images: kindly please explain these parts in the answer.

How we can we applied to a group of images at a time?

I tried to run the code and it shows results upto the hisdtogram. From that poertion how can we proceed?

THANKS IN ADVANCE

1. can you please explain the method. The image you attached is corresponding to the first image. is it? The method is explained in numerous comments in the code. Basically I extract the color bar to create a look up table to convert the RGB image into a temperature image.
2. How can we use the eautaion for conctructing the images: kindly please explain these parts in the answer. Again, it's well explained by tons of comments in the code. There are probably as many lines of comments in there as lines of code. The main line of code is this: indexedImage = rgb2ind(rgbImage, storedColorMap)
3. How we can we applied to a group of images at a time? You could make the main part into a function and call that function in a loop. See the FAQ: https://matlab.fandom.com/wiki/FAQ#How_can_I_process_a_sequence_of_files?
4. I tried to run the code and it shows results upto the hisdtogram. From that poertion how can we proceed? At the end of the script you have the temperature image. It's an image where each pixel location is the temperature. You must know what you want to do with that image. If you don't know why you want the image, then why are you even working with the image at all. Maybe you just want the mean temperature of the image, or maybe you want the area of some hot region in the image. Once you know what you want to do you use standard image analysis functions to measure it. If you're still confused, see my Image Segmentation Tutorial: https://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862&sort=downloads_desc

Use gtext() to display the equation
