Abstract
Various techniques are provided to process infrared images. In one implementation, a method of processing infrared image data includes receiving infrared image data associated with a scene. The infrared image data comprises a plurality of pixels arranged in a plurality of rows and columns. The method also includes selecting one of the columns. The method also includes, for each pixel of the selected column, comparing the pixel to a corresponding plurality of neighborhood pixels. The method also includes, for each comparison, adjusting a first counter if the pixel of the selected column has a value greater than the compared neighborhood pixel. The method also includes, for each comparison, adjusting a second counter if the pixel of the selected column has a value less than the compared neighborhood pixel. The method also includes selectively updating a column correction term associated with the selected column based on the first and second counters.
