In lovetoken/bsid: Background Subtraction and Image Denoising (BSID)

creating M matrix

M matrix 만들기 creat_vm()

creat_vm(path="./example_data/airport_sub/")
M <- bsid_env$M

M 확인하기 save_anipic()

save_anipic(M, save.name="airport_sub_M")

PCP algorithm

Principal Component Pursuit algorithm 를 이용하여 L, S matrix 만들기 PCP()

PCP(M)
L <- bsid_env$L
S <- bsid_env$S

L, S 확인하기

save_anipic(L, save.name="airport_sub_L")
save_anipic(S, save.name="airport_sub_S")

L matrix

S matrix

M matrix 에 PWNPoint type White Noise 추가하기

임의위치의 픽셀값을 1로 부여하여 잡음을 추가 WN_point()

WN_point(M)
Mstar <- bsid_env$Mstar

M⋆ 확인하기

save_anipic(Mstar, save.name="airport_sub_Mstar")

Mstar PCP

PCP(Mstar)
Lstar <- bsid_env$L
Sstar <- bsid_env$S

save_anipic(Lstar, save.name="airport_sub_Lstar")
save_anipic(Sstar, save.name="airport_sub_Sstar")

L⋆ 확인하기

S⋆ 확인하기

Image Denoising

M′ 만들기 (method="MDMR_filter")

denoising(Mstar, method="MDMR_filter", W0=1, lambda=0.1)
Mprime <- bsid_env$prime

save_anipic(Mprime, save.name="airport_sub_Mprime")

M′ 확인하기

S′ 만들기 (method="median_filter")

denoising(Sstar, method="MDMR_filter", W0=1, lambda=0.1)
Sprime <- bsid_env$prime

save_anipic(Sprime, save.name="airport_sub_Sprime")

S′ 확인하기

S′ + L⋆ 확인하기

Mpprime <- Sprime + Lstar

save_anipic(Mpprime, save.name="airport_sub_Mpprime")

MSE compare

∣ ∣ M − M′ ∣ ∣F

norm(M-Mprime, type="F")

## [1] 83.78163

∣ ∣ M − (S′ + L⋆) ∣ ∣F

norm(M-Mpprime, type="F")

## [1] 43.66876

∣ ∣ M − M′ ∣ ∣F  ≥   ∣ ∣M − (S′ + L⋆) ∣ ∣F
