Hello, Pat.
It is possible to count the nails.
You just need to perform some morphologichal operations, such as
erosion, area open, etc.
Then, in the next step you need to count the objects. You can use regionsprops command.
Here my demo :
Irgb = imread('n7vGa.jpg');Igray = rgb2gray(Irgb);Ibw = im2bw(Igray, 0.9);se = strel('square',2);Imorph = imerode(Ibw,se);Iarea = bwareaopen(Imorph,130);Idiff = Imorph - Iarea;Ifinal = bwareaopen(Idiff,70);stat = regionprops(Ifinal,'BoundingBox');str = sprintf('number of detected nails : %d', length(stat));imshow(Irgb); title(str); hold on;for cnt = 1 : length(stat) bb = stat(cnt).BoundingBox; rectangle('position',bb,'edgecolor',rand(1,3)); endAnd the result :
Is that you meant??
Try the command
which realI suspect that you have a variable defined in your workspace that is named real when you are really trying to call the function real. If this is the case, clear real and then try the code.
clear real
