title = "Conversion of infrared grey-level image into temperature field by polynomial curve fitting",
abstract = "A simple method to convert the infrared gray-level image into temperature field is developed by using least squares polynomial curve fitting. In this method, the correspondence between the infrared gray-level image and the associated temperature field for various emissivity values and temperature range is analyzed first. Then a second-order polynomial can be applied to fit the correspondence between the gray-level image and the associated temperature field as a function of emissivity. For multiple conversions of temperature ranges, the constants of the fitted polynomial in multiple ranges can be further fitted as a function of emissivity and temperature range. Test of the method on a cup of hot water was done. An average error less than 1% was achieved between the proposed method and the commercial ones.",
