1. A method of generating a single observation image, the method comprising:
receiving, by one or more processors, a plurality of images, each image of the plurality of images capturing a component as a heating element traverses relative to the component along a traversing direction and applies heat thereto, the component having a metallic structure and a coating;
generating, by the one or more processors, a plurality of masked images by:
for each image of the plurality of images, positioning, by the one or more processors, a masking window relative to the heating element; and
applying, by the one or more processors, thermal data to pixels within the masking window of each image of the plurality of images;
determining a minimum or maximum value associated with each pixel of the pixels within the masking window of each image of the plurality of images over the plurality of masked images based at least in part on the applied thermal data; and
generating the single observation image of the component using the plurality of masked images such that the determined minimum or maximum value associated with each of the pixels in the plurality of masked images is represented in the single observation image.
