Table 1

The pattern-classify mapping strategies of orthogonal cascade classifier.

Pattern-classify mapping strategy
Condition	Output
(1) If 𝐷^−1low(ℎ𝐶)>𝑣, where 𝑣 is the threshold of holding area,	𝑆sign𝐹ℎ(𝑥),sign𝐹𝑣(𝑥).
(2) Else if 𝛾∈(𝑢,𝑢^−1), where 𝛾=^def(ℎ𝐶(high,𝑑1)+ℎ𝐶(high,𝑑4))/(ℎ𝐶(high,𝑑2)+ℎ𝐶(high,𝑑3))>0 and 𝑢∈(0,1) is the threshold to distinguish a cross as the intersection of two orthogonal paths,	𝑆sign𝐹ℎ(𝑥),sign𝐹𝑣(𝑥).
(3) Else if 𝛾∈(0,𝑢),	𝑆sign𝐹𝑣(𝑥),0.
(4) Else 𝛾∈(0,𝑢),	𝑆sign𝐹ℎ(𝑥),0.
