slic的matlab实现

以下是SLIC算法的Matlab实现：

close all;
clc;

% 读取图像
I = imread('1.jpg');
figure, imshow(I);

% 设置参数
s = 15; % 超像素尺寸
errTh = 10^-2; % 错误阈值
wDs = 0.5^2; % 空间权重

% 执行SLIC算法
Label = SLIC(I, s, errTh, wDs);

% 显示超像素轮廓
marker = zeros(size(Label));
[m, n] = size(Label);
for i = 1:m
    for j = 1:n
        top = Label(max(1, i-1), j);
        bottom = Label(min(m, i+1), j);
        left = Label(i, max(1, j-1));
        right = Label(i, min(n, j+1));
        if ~(top == bottom && bottom == left && left == right)
            marker(i, j) = 1;
        end
    end
end
figure, imshow(marker);

% 标记超像素区域
I2 = I;
for i = 1:m
    for j = 1:n
        if marker(i, j) == 1
            I2(i, j, :) = 0;
        end
    end
end
figure, imshow(I2);

% 显示连通域处理后的聚类结果
temp = mod(Label, 20) + 1;
figure;
imagesc(label2rgb(temp-1, 'jet', 'w', 'shuffle'));
title('连通域处理后的聚类结果');
axis image;
axis off;
