Find the boundary of a shape in a pixel set
Find the boundary of a shape in a pixel set
boundary(px, depth = 1, high_connexity = FALSE)
px |
pixel set |
depth |
boundary depth (default 1) |
high_connexity |
if FALSE, use 4-point neighbourhood. If TRUE, use 8-point. (default FALSE) |
px.diamond(10,30,30) %>% boundary %>% plot px.square(10,30,30) %>% boundary %>% plot px.square(10,30,30) %>% boundary(depth=3) %>% plot px <- (px.square(10,30,30) | px.circle(12,30,30)) boundary(px,high=TRUE) %>% plot(int=TRUE,main="8-point neighbourhood") boundary(px,high=TRUE) %>% plot(int=FALSE,main="4-point neighbourhood")
