AMSMW

The geometric centre of the RROI

\(R=\text {w}-20, \text{ iterations }=250, \text{ if } \min (\text {h}, \text {w})>20, \text{ and } \text {h}>1.5 \text {w}\);

\(R=\text {w}-20 \text{, } \text{ iterations }=120, \text{ if } \min (\text {h},\text {w})>20, \text{ and } \text {w}/1.5<\text {h}<1.5 \text {w}\);

\(R=\text {w}-10 \text{, } \text{ iterations }=250, \text{ if } \min (\text {h},\text {w})<20, \text{ and } \text {h}>1.5 \text {w}\);
