How do you find the perimeter of a binary image?
BW2 = bwperim( BW ) returns a binary image that contains only the perimeter pixels of objects in the input image BW . A pixel is part of the perimeter if it is nonzero and it is connected to at least one zero-valued pixel. BW2 = bwperim( BW , conn ) also specifies the pixel connectivity, conn .
How do you find the area of binary images?
Description. total = bwarea( BW ) estimates the area of the objects in binary image BW . total is a scalar whose value corresponds roughly to the total number of on pixels in the image, but might not be exactly the same because different patterns of pixels are weighted differently.
How to fill holes in binary image matlab?
BW2 = imfill( BW ,"holes") fills holes in the input binary image BW . In this syntax, a hole is a set of background pixels that cannot be reached by filling in the background from the edge of the image. BW2 = imfill( BW , conn ,"holes") fills holes in the binary image BW , where conn specifies the connectivity.
How does Bwlabel work in Matlab?
L = bwlabel( BW ) returns the label matrix L that contains labels for the 8-connected objects found in BW . L = bwlabel( BW , conn ) returns a label matrix, where conn specifies the connectivity. [ L , n ] = bwlabel(___) also returns n , the number of connected objects found in BW .
