Abstract
A method for thermal imaging includes extracting pixel intensity data from a plurality of images corresponding to electromagnetic radiation emitted from one or more targets, creating an array for each image pixel in the plurality of images, wherein each pixel array represents a distribution of intensity data from corresponding pixels in each of the images, removing from each pixel array an amount of intensity data such that a remaining amount of intensity data represents an approximate equivalent to a distribution of intensity data uncontaminated by interference; and generating a thermal image representing the one or more targets based on the remaining amount of intensity data in each pixel array.
Claims19
A method for generating a thermal image of a glass gob, the method comprising:
- extracting pixel intensity data from a plurality of images corresponding to electromagnetic radiation emitted from one or more glass gobs;
- generating an array of intensity data for each representative pixel in the plurality of images, wherein each array represents a distribution of intensity data from corresponding pixels in each of the images;
- filtering the intensity data in each array to exclude an amount of intensity data such that a remaining amount of intensity data represents a distribution of intensity data uncontaminated by interference;
- and
- generating a thermal image of a glass gob based on the remaining amount of intensity data in each array.
