Image processing based on ambient air attributes
View Patent ↗A method of processing a digital image captured by a camera includes providing an ambient air measuring device associated with the camera; using the ambient air measuring device to measure air attributes at substantially the time the digital image was captured; determining a transform for modifying the digital image from the measured air attributes; and applying the transform to the digital image to produce an improved digital image.
1. A method of processing a digital image of a scene captured by a camera comprising:
(a) providing an ambient air measuring device associated with the camera;
(b) using the ambient air measuring device to measure air attributes at substantially the time the digital image was captured; and
(c) classifying regions of the digital image according to the type of material in the scene based on the measured air attributes.
2. The method of claim 1 , wherein the material type includes inanimate and animate objects.
3. The method of claim 2 , wherein the inanimate objects include sky, grass, water, clouds, pavement, road surface, snow, automobiles, or walls.
4. The method of claim 2 , wherein the animate objects include humans or animals.
5. The method of claim 2 , wherein the regions are classified by learning the probabilities that a given material appears in an digital image captured with a variety of measured air attributes.
6. The method claimed in claim 1 , wherein the measured air attribute is ambient air temperature.
7. The method of claim 1 , a stored air attribute for each digital image also includes the time each such digital image was captured and step d) includes using the time of the captured digital images.
