Figure 7. The results of applying the decision rules: (a) R1, (c) 
R2, (e) R3 for the CASI-48 image and (b) R1, (d) R2, 
(f) R3 for the CASI-32 image. 
About the fusion of primary results, we can say that the final 
target maps is more reliable and precise. Especially for CASI- 
32 images, the results of R3 in which all of the techniques have 
detected the pixel under test as target material. Also, they are 
able to identify the single non-target pixels surrounded by target 
pixels. But for CASI-48 images the results of R2 are better than 
others. So, results of fusion are more affected by the size of 
resolution than the rules. Then, however the fusion technique 
can enhance the results, but the role of primary mapping 
techniques is important and may be applied for pure target 
mapping.
