             abstract = "Machine design of a signal or image operator involves estimating 
                         the optimal filter from sample data. In principle, relative to the 
                         error measure used, the optimal filter is best; however, owing to 
                         design error, the designed filter might not perform well. In 
                         general it is suboptimal. The envelope constraint involves using 
                         two humanly designed filters that form a lower and upper bound for 
                         the designed operator. The method has been employed for binary 
                         operators. This paper considers envelope design for gray-scale 
                         filters, in particular, aperture filters. Some basic theoretical 
                         properties are stated, including optimality of the design method 
                         relative to the constraint imposed by the envelope. Examples are 
                         given for noise reduction and de-blurring.",
