我試圖從掃描圖像中提取浮游生物.

大綱也不錯,但是,現(xiàn)在我不知道如何提取圖像,因此可以單獨保存每個浮游生物.我嘗試使用標簽,但是有很多噪音,它標出了每一個規(guī)格.我想知道是否有更好的方法來做到這一點.

這是我的代碼：

I = imread('plankton_2.jpg');

figure, imshow(I), title('original image');

[~, threshold] = edge(I, 'sobel');

fudgeFactor = .5;

BWs = edge(I,'sobel', threshold * fudgeFactor);

figure, imshow(BWs), title('binary gradient mask');

se90 = strel('line', 3, 90);

se0 = strel('line', 3, 0);

BWsdil = imdilate(BWs, [se90 se0]);

figure, imshow(BWsdil), title('dilated gradient mask');

BWdfill = imfill(BWsdil, 'holes');

figure, imshow(BWdfill);

title('binary image with filled holes');

BWnobord = imclearborder(BWdfill,1);

figure, imshow(BWnobord), title('cleared border image');

seD = strel('diamond',1);

BWfinal = imerode(BWnobord,seD);

BWfinal = imerode(BWfinal,seD);

figure, imshow(BWfinal), title('segmented image');

BWoutline = bwperim(BWfinal);

Segout = I;

Segout(BWoutline) = 0;

figure, imshow(Segout), title('outlined original image');

label = bwlabel(BWfinal);

max(max(label))

for j = 1:max(max(label))

[row, col] = find(label == j);

len = max(row) - min(row)+2;

breadth = max(col)-min(col) +2;

target = uint8(zeros([len breadth]));

sy = min(col)-1;

sx = min(row)-1;

for i = 1:size(row,1)

x = row(i,1)-sx;

y = col(i,1) - sy;

target(x,y)=I(row(i,1),col(i,1));

end

mytitle =strcat('Object Number:',num2str(j));

figure, imshow(target);mytitle;

end

for j = 1:max(max(label))

[row, col] = find(label == j);

len = max(row) - min(row)+2;

breadth = max(col)-min(col) +2;

target = uint8(zeros([len breadth]));

sy = min(col)-1;

sx = min(row)-1;

for i = 1:size(row,1)

x = row(i,1)-sx;

y = col(i,1) - sy;

target(x,y)=I(row(i,1),col(i,1));

end

mytitle =strcat('Object Number:',num2str(j));

figure, imshow(target);mytitle;

end
