1. A method for selecting a set of features for adjusting the exposure of images, the method comprising: placing a set of features in a master feature set M; initializing a current feature set C to a null value; performing the following for each feature F in the master feature set M: adding the current feature set C and the feature F to form a temporary feature set S; calculating an error E using the set S as a feature set; and performing at least one of the following: determining that the error E is less than a minimum error E MIN , assigning the value of E to E MIN and recording the identity of feature F in a variable F MIN ; and determining that the error E is greater than a minimum error E MIN , leaving the values of E MIN and F MIN unchanged; performing one of the following: determining that E MIN is less than a global error E G , assigning the value of E MIN to E G , adding the feature F recorded F MIN to the set C, and deleting the feature F recorded in F MIN from the set M, and determining that the set M is empty; and determining that E MIN is less than a global error E G , and leaving the value E G , the set C, and the set M unchanged; and selecting the set C as the set of features for adjusting the exposure of images.
