Bro ask question clearly..!
According my understanding simply convert image into gray(0 to 255) image and then at that white line pixels having high values (255),then you have to apply box filter and then apply thresholding,then you get what you want.
if true %RGB image is input image I = rgb2gray(RGB) %filter for Smoothness & Removing finner detail. %Thresholding end
gray Image: https://in.mathworks.com/help/matlab/ref/rgb2gray.html
thresholding: https://in.mathworks.com/discovery/image-thresholding.html
filter: https://in.mathworks.com/help/images/ref/imboxfilt.html
