Application of optical character recognition in the processing in the processing of thermal images

The present-day reliance on metadata in obtaining information from thermal images means that in the absence of metadata, estimating temperatures from thermal images would have to be done with user intervention, which is time-consuming when there are many thermal images to consider. This research int...
