Description: The Direct Lookup Model makes use of the Direct Lookup operator to map integer values in the Input through a lookup table. For example, if inputs are thematic (e.g., clump image) and a table (e.g. a table associating clump value to original class value), Direct Lookup will replace the DN (digital number) from the input thematic image, say, n, with the value in the nth input row of Table.
