Isolating Scissors in a binary image

Hey so I am stuck on this problem and would love any advice on how to start to solve it.

I have this binary image and I want to isolate the scissors from the rest of the objects in the image. My problem is I am not sure how to start.

Any help would be great!

Hi Adam,

This is similar to extracting a class of objects from a binary image using properties.

Find the code below for detecting the scissors using area property: -

Img = imread('data.png');   % read original image
complementImg = imcomplement(Img);  % complement image
grayImg = rgb2gray(complementImg); % convert to grayscale
binImg = imbinarize(grayImg);   % binarize

% Extract scissors using area property
outImg = bwpropfilt(binImg, 'area', [1200 1500]);  

% display original & output image
figure;
imshowpair(Img,outImg,'montage');

Output: -

Referring you to the following links, which might help you in understanding the code above: -https://www.mathworks.com/help/images/ref/imcomplement.htmlhttps://www.mathworks.com/help/matlab/ref/rgb2gray.htmlhttps://www.mathworks.com/help/images/ref/bwpropfilt.html
