Applying OCR in the Processing of Thermal Images with Temperature Scales

Present-day thermal image processing is dependent on the use of metadata. This metadata, such as colour-to-temperatures indices that help the conversion of the colour value of every pixel in the image into a temperature reading, may be stored within the image files as supplementary information that is not immediately apparent from a glance of the image. Instead, they are kept within the image bytes, to be fetched by metadata-dependent programs that had been designed to examine to work with said metadata.
