I am currently working on an image and I wanted to know how I can count the numbers of buckles (lines) on an image. Find attached is the image in question and I wait in anticipation for a positive response.

You can refer the following code snippet to count the approximate number of number of buckles using bwlabel function:
% Read image
I = imread("0050.png");
% Binarize image
BW = im2bw(I);
% Label connected components in 2-D binary image
% numOfConnComponents is approximately equal to number of buckles
[labels numOfConnComponents] = bwlabel(~BW);
% Show the labelled connected components
coloredLabelsImage = label2rgb(labels, 'hsv', 'k', 'shuffle');
imshow(coloredLabelsImage);
You can use bwareaopen function to further improve the accuracy of detected number of components by removing smaller buckles from the binary image.
