Choosing the Optimal Spatial Domain Measure of Enhancement for Mammogram Images

Figure 3

Image enhancement using unsharp masking. Higher unsharp mask scale results in higher contrast in enhanced image.

(a) Original image

(b) Unsharp mask scale = 0.5

(c) Unsharp mask scale = 0.8

(d) Unsharp mask scale = 1.1

(e) Unsharp mask scale = 1.4

(f) Unsharp mask scale = 1.7
