Question

我修改了我的代码以进行细分处理。但我得到一个＆＃34;指数超过矩阵维度＆＃34;错误。代码如下。

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个单词的图像数据，我需要分割所有图像＆＃39;将数据转换为字符图像，并将它们保存为每个分段字符的不同文件。我需要按顺序保存它。

我已经尝试改变

subImage = i(:, startingColumns(k):endingColumns(k));

到

subImage = i( startingColumns(k):endingColumns(k),:);

但它仍然没有奏效。我不知道代码有什么问题。有人可以解释和帮助吗？

Answer 1

您可能希望更改第64行k中的endingColumns(k)。从代码看，startingColumns与endingColumns的元素数量相同。

如何解决＆＃34;指数超过矩阵维度＆＃34;在分割过程中（Matlab）
