Abstract :
This work reports and illustrates the application of optimal filtering to enhance sketch contours on infrared photographs of wood paintings. Three approaches to edge detection by using optimal filtering-symmetric exponential filter of an infinitely large window size-were tested. Then one method was chosen to have a fine tuning of its parameters
