clc; clear all; close all;
img = imread('demo.jpg');
J = rgb2hsv(img);
s = mat2gray(J(:,:,2));
bw = im2bw(s, 0.2);
bw = imclose(bw, strel('line', 5, 0));
bw = bwareaopen(bw, 6);
stats = regionprops(bw);
figure;
imshow(img);
for i = 1 : length(stats)
    rect = stats(i).BoundingBox;
    hold on; rectangle('Position', rect, 'EdgeColor', 'm', 'LineWidth', 1);
    if rect(3) > 20
        rectangle('Position', rect, 'EdgeColor', 'r', 'LineWidth', 1);
        imi = imcrop(img, round(rect));
        imi2 = imresize(imi, 3, 'bilinear');
        txt = ocr(imi2);
        text(rect(1), rect(2)-rect(4)/2, txt.Words{1}, 'Color', 'g', 'FontSize', 16)
    end
end
