Convert image to binary
im2 = im2bw(im, thresh)
thresh
in the range [0,1], regardless of the class of the input image.im2bw
convert intensity or RGB images to binary
images. The output is a boolean matrix, which has value of
%T
for all pixels in the input image with luminance
grater than thresh
and %F
for all
the other pixels. (You specify thresh
in the range
[0,1], regardless of the type of the input image.)
