The document outlines an algorithm that measures the areas between an isothermal profile line and amplitude line to quantify temperature variations in pixels across an image. It defines positive amplitude as the area above the amplitude line and negative amplitude as the area below. The algorithm calculates these area values starting from the lowest temperature point in the center of the image outwards.
