Matlab雕刻Seam函数调用

Question

我想用Matlab在图像中进行缝合。

如果我只使用脚本而不是通过调用函数来实现它，它就可以工作。当我将脚本作为一个函数并尝试调用它时会出现问题

我使用的代码

最终剧本：我用来反复调用该函数的脚本，所以我得到了结果

clear all;
close all;

%Image = 'mall.jpg';

Image_Array = imread('mall.jpg');

%We keep the dimension of the image array
[Row_Count,Column_Count,Colour] = size(Image_Array);

Image = double(Image_Array)/255;
Image = rgb2gray(Image);

for i = 1 : 10
[Image_Array,Row_Count,Column_Count]=Vertical_Seam(Image_Array,Row_Count,Column_Count);
imshow(Image_Array);
end

Vertical Seam：我用来做缝合工作的脚本。这是我想把它作为一个函数的文件，并在Finalscript中调用它，但我不知道如何（你会注意到我试图做一个功能，但因为它没有工作我把它放在％）

%function [Final_Image,Row_Count,Column_Count] = Vertical_Seam(Image_Array,Row_Count,Column_Count)

Image_Array = imread('mall.jpg');

%We keep the dimension of the image array
[Row_Count,Column_Count,Colour] = size(Image_Array);

Image = double(Image_Array)/255;
Image = rgb2gray(Image);

for repeat = 1 : 10

%Calculate the energy
[E_x,E_y] = gradient(Image);
Energy = abs(E_x) + abs(E_y);

%We run the image and keep the minimum sum-energy in Image_Array
Cumulative_Energy = zeros(Row_Count,Column_Count);

% i represent rows 
% j represent columns
for i = 1 : Row_Count
    for j = 1 : Column_Count
        if i==1
            Cumulative_Energy(i,j) = Energy(i,j);
        elseif i>1
                if j==1
                   temp1 = [Cumulative_Energy(i-1,j),Cumulative_Energy(i-1,j+1)];
                   Cumulative_Energy(i,j) = Energy(i,j) + min(temp1);
                elseif j>1 && j<Column_Count
                   temp2 = [Cumulative_Energy(i-1,j-1),Cumulative_Energy(i-1,j),Cumulative_Energy(i-1,j+1)];
                   Cumulative_Energy(i,j) = Energy(i,j) + min(temp2);   
                elseif j==Column_Count
                   temp3 = [Cumulative_Energy(i-1,j-1),Cumulative_Energy(i-1,j)];
                   Cumulative_Energy(i,j) = Energy(i,j) + min(temp3);
                end
        end
    end
end

%Find the minimum value from last column

temp_min = Cumulative_Energy(Row_Count,1);
point_min = 1;

for j = 2 : Column_Count
    if Cumulative_Energy(Row_Count,j)<temp_min
        temp_min = Cumulative_Energy(Row_Count,j);
        point_min = j;
    end
end

%Start from the minimum value from last column and backtrack to find the minimum seam

%We need an array to keep minimum energy in every row while
%backtracking
Keep_Seam = zeros(Row_Count,1);
Keep_Seam(Row_Count) = temp_min;

%We need also the point of the minimum energy (the number of column)
Keep_Point = zeros(Row_Count,1);
Keep_Point(Row_Count) = point_min;

%Paint the pixel
Image_Array = Image_Colouring(Image_Array,Row_Count,point_min);


for i = Row_Count : -1 : 1
    if i==1
        if point_min==1
            Tmp1 = [Cumulative_Energy(i,point_min),Cumulative_Energy(i,point_min+1)];
            Keep_Seam(i) = min(Tmp1);

            if min(Tmp1)==Cumulative_Energy(i,point_min)
               Keep_Point(i) = point_min; 
            else
               Keep_Point(i) = point_min+1;
               point_min = point_min+1;
            end

            Image_Array = Image_Colouring(Image_Array,i,point_min);

        elseif point_min==Column_Count

               Keep_Point(i) = point_min-1;

我想连接这两个文件，以便Finalscript将Verticalseam称为函数而不是脚本
