Matlab 如何通过相关像素值缓冲像素？

我可以使用什么方法通过相关像素值缓冲像素？例如，左侧的图像显示像素半径值范围为0-5（注意“黑色”值为0）的光栅图像。右边的图像显示了我试图基于这些像素值生成的缓冲区。每个堆栈交换策略，我还包括一个用于可复制数据的MATLAB脚本

一种方法：

% Generate a grid of 0's to begin with.
m = zeros(300, 400, 'uint8');

% Generate 1000 random pixels.
numRandom = 9;
linearIndices = randi(numel(m), 1, numRandom);

% Assign a radius value of 1-5 for each pixel
m(linearIndices) = randi(5, [numel(linearIndices) 1]);



%%
buffer = false(size(m));
for radius =1:5 % update to actual range
    im_r  = m==radius;
    se    = strel('disk',radius);
    im_rb = imfilter(im_r, double(se.getnhood()));

    buffer = buffer | im_rb;
end

imshowpair(m,buffer,'montage');

编辑：nvm，这里的“缓冲区”一词的用法不清楚。@Ashish您在提供的解决方案中使用的“缓冲区”是正确的。非常感谢@Ashish。这是一个创造性的简单解决方案。
