How to crop different size of plant seed automatically?

Hello everyone.

I have a microscope scanned seed image. I want to find the boundary of the edge seeds and then crop the boundary of the edge and save all the cropped seeds. What should I do? For example: first image is original image.

In the second picture, the total number of plant seeds is around 10.

3rd, I find the boundary of the edge and at least I want to crop a few.

How to crop as shown in last figure?

Hi Ariunzaya,

I understand that you have the image which is having all the blue bounding boxes and you are looking for a method to extract all the different bounding boxes as a seperate image.

To crop multiple bounding boxes from an image and save each crop as a separate image, you can follow the steps outlined below. This example assumes you have the coordinates of the bounding boxes in the format [x, y, width, height], where (x, y) are the coordinates of the top-left corner of the bounding box.

Here's a basic MATLAB script that demonstrates how to do this:

% Load the image
image = imread('path_to_your_image.jpg');

% Assuming you have 3 bounding boxes for demonstration
boundingBoxes = [
    100, 50, 120, 150; % Box 1
    250, 75, 100, 125; % Box 2
    400, 100, 150, 200; % Box 3
];

% Number of bounding boxes
numBoxes = size(boundingBoxes, 1);

% Loop through each bounding box and crop the image
for i = 1:numBoxes
    bbox = boundingBoxes(i, :);
    x = bbox(1);
    y = bbox(2);
    width = bbox(3);
    height = bbox(4);
    
    % Crop the image based on the bounding box
    croppedImage = imcrop(image, [x, y, width, height]);
    
    % Save the cropped image
    croppedImageFilename = sprintf('cropped_image_%d.jpg', i);
    imwrite(croppedImage, croppedImageFilename);
end

I hope it helps!
