By my understanding you want to plot 8 sprays in 8 different figures. You can find the attached code for extracting boundaries from sprays and plot in different figures.
clc
clear all
close all
%bsp image
i = imread('bsp.jpg');
figure
imshow(i);
bw = imbinarize(i);
x = bwboundaries(bw);
%To plot all the sprays on single figure
figure
for k = 1:length(x)
boundary = x{k};
plot(boundary(:,2), boundary(:,1));
hold on;
end
%To plot 8 sprays on 8 figures
hold off;
for k = 1:length(x)
figure
boundary = x{k};
plot(boundary(:,2), boundary(:,1));
end
Hope it helps.
