1. A method of displaying information representative of a scene, comprising the steps of: acquiring information representative of the scene from a detector configured to process information in a first range of wavelengths;filtering the acquired information more as the amount of thermal content is increased; anddisplaying an output for viewing by an operator, further comprising the step of calculating a display value for a display target pixel based on received values of surrounding pixels, wherein the display value equals approximately 1N⁢∑Pij*Aij where Pij is a matrix of received pixel values, Aij is a matrix of kernel values, and N equals the sum of Aij. 2. The method of displaying information of claim 1, wherein the first range of wavelengths is approximately 750 nm-14,000 nm. 3. The method of displaying information of claim 2, wherein the first range of wavelengths is approximately 7,000 nm-14,000 nm. 4. The method of displaying information of claim 1, wherein the acquiring information step comprises generating a two-dimensional intensity mapping of the scene. 5. The method of displaying information of claim 4, wherein the intensity mapping comprises a plurality of individual pixels arranged in rows and columns. 6. The method of displaying information of claim 5, wherein the intensity mapping has a received target pixel surrounded by a plurality of surrounding received pixels. 7. The method of displaying information of claim 1, wherein the display value is displayed in the display for viewing by an operator. 8. The method of displaying information of claim 1, wherein the thermal content is calculated by determining the difference between the lowest received pixel value of interest and the highest received pixel value of interest. 9. A vision system for viewing a scene, comprising: a housing;an infrared detector at least partially disposed within the housing;a filter coupled to the detector for filtering an output of the detector and generating a new output, the filter configured to set the amount of filtering based on a thermal content of received information; anda display for displaying the new output for an operator wherein the filter calculates a display value for a display target pixel based on a received value of pixels, wherein the display value equals approximately 1N⁢∑Pij*Aij where Pij is a matrix received pixel values, Aij is a matrix of kernel values, and N equals the sum of Aij. 10. The vision system of claim 9, wherein a greater amount of thermal content results in a greater amount of filtering. 11. The vision system of claim 9, wherein the thermal content is calculated by determining the difference between the lowest received pixel value of interest and the highest received pixel value of interest. 12. The vision system of claim 9, wherein the detector detects in a range of wavelengths from approximately 750 nm to approximately 14,000 nm. 13. The vision system of claim 12, wherein the range of wavelengths is from approximately 7,000 nm to approximately 14,000 nm. 14. The vision system of claim 9, wherein the display has a plurality of individual pixels arranged in rows and columns. 15. The vision system of claim 9, wherein the display value is displayed in the display for viewing by an operator. 16. The vision system of claim 9, wherein the filter comprises a multi-row, multi-column buffer and a multi-row, multi-column convolver.
