Two-stage Binary Image Operator Design: an Approach Based on Interaction Information

2007 XX Brazilian Symposium on Computer Graphics and Image Processing (SIBGRAPI 2007)  
We address the problem of binary image operator design over large windows by breaking it into two phases. Firstly, we design several operators over small sub-windows of the main window. The outputs of these first level operators are then combined into a global operator. We devise a heuristic, motivated by Information Theory, for breaking the main window into sub-windows. Preliminary results show that the proposed scheme improves operator performance over single-level operators.
