I have a binary image, and have extracted the largest and second largest images from a grayscale image (using bwareafilt). This gives me the image below:
How do i extract the image on the right (the second largest image)?
Using regionprops I have the Area, Centroid and Bounding Box for both blobs, but I am not sure how to use these values to extract the image on the right.
Thank you.

large_1=bwareafilt(binary_image,1); %Extracting Large Blob
large_2=binary_image & ~large_1; % Logical Operation to get 2nd largest Blob
large_2=bwareafilt(large_2,1); % Remove extra small blobs
imshow(large_2);
