我修改了我的分割過程的代碼。但是我得到了「索引超出矩陣維度」的錯誤。代碼如下。如何解決分割過程中的「索引超過矩陣維」(Matlab)
for z = 1: 300
name1 = strcat ('data (',int2str(z),').png');
name2 = strcat ('D:\1. Thesis FINISH!!!\Data set\0 Isolated Dataset\Advertising Bold 14\source\', name1);
a = imread (name2);
myFolder = 'D:\1. Thesis FINISH!!!\Data set\0 Segmented Character\coba';
%% Binarization %%
level = graythresh (a);
b = im2bw (a, level);
%% Complement %%
c = imcomplement (b);
%% PadArray %%
i=padarray(c,[0 10]);
%% Vertical Projecttion for Character Segmentation
verticalProjection = sum(i, 1);
set(gcf, 'Name', 'Segmentation Trial', 'NumberTitle', 'Off')
subplot(2,2,1);imshow(i);
subplot(2,2,3);
plot(verticalProjection, 'b-');
grid on;
% *Defining the threshold to determine baseline area* %
threshold=max(verticalProjection)/3;
% threshold=min(verticalProjection)/3;
% threshold = 5; % Threshold >0 used to detect the baseline of cursive characters
thresholdedProjection=verticalProjection > threshold;
count=0;
startingColumnsIndex=0;
for j =1:length(thresholdedProjection)
if thresholdedProjection(j)
if(count>0)
startingColumnsIndex=startingColumnsIndex+1;
startingColumns(startingColumnsIndex)= j-floor(count/2);
count=0;
end
else
count=count+1;
end
end
endingColumns=[startingColumns(2:end)-1 j-floor(count/2)];
% *Extract each region, result of segmentation process* %
y=1;
for k = 1 : length(startingColumns)
% Get sub image of just one character
subImage = i(:, startingColumns(k):endingColumns(k));
% im = subImage;
s = subImage;
% Normalization using algorithm 2 %
p = normalization2 (s);
subplot(2,2,2);
imagesc (p);
axis equal off;
pause (1);
% figure,
imshow (p);
% Morphological Operation - Thinning %
t = bwmorph(p,'thin',Inf);
end
% savename = char (strcat (myFolder, name1));
imwrite (t, fullfile (myFolder, sprintf ('data.%d.png', y)));
y = y+1;
end;
我有300個字的圖像數據,以及我需要段中所有的圖像數據爲字符圖像,並將其保存爲每個分段的字符作爲不同的文件。我需要順序保存它。
我已經嘗試改變
subImage = i(:, startingColumns(k):endingColumns(k));
到
subImage = i(startingColumns(k):endingColumns(k),:);
但它仍然沒有奏效。我不知道代碼有什麼問題。任何人都可以請解釋和幫助?
你在哪一行得到錯誤? – Salman
