Overlay a image with plot

65 views (last 30 days)
Hey Guys,
i want to overlay a image with a the plot i made,
The first Subplot is just the Plot an the second shall be the combination.
Here is my Code:
I = imread('Bild_1.jpg');
I=I(:,:,1);
white = sum(I,2);
[Rows,numCols] = size(I);
x0=0;
y0=0;
width=numCols;
height=Rows;
set(gcf,'position',[x0,y0,width,height])
subplot(1,2,1)
plot(white);
view([90 90]);
saveas(gcf,'Plot_01.png',[x0,y0,width,height]);
P1=imread('Plot_01.png');
P2= imrotate(P1,90,'bicubic','crop');
subplot(1,2,2)
imshowpair(P2,I,'blend','Scaling','joint')
My Problem is that the Plot and the image are in a 90° Angle to each other. Moreover the saved Plot doest not have the same (Pixel)Size.
Hope you can help me

Below are some suggestions: (only for the above code)
  1. (line 14 - 17) Instead of using subplots use figure and save the plot
  2. (line 20, 21) Rotate the image first and then resize it
Below is the code after making changes:
I = imread('Bild_1.jpg');
I=I(:,:,1);
white = sum(I,2);
[Rows,numCols] = size(I);
x0=0;
y0=0;
width=numCols;
height=Rows;
figure
set(gcf,'position',[x0,y0,width,height])
plot(white);
view([90 90]);
saveas(gcf,'Plot_01.png',[x0,y0,width,height]);
P1=imread('Plot_01.png');
P1 = imrotate(P1,90);
P2 = imresize(P1,[Rows,numCols],'bicubic');
figure
imshowpair(P2,I,'blend','Scaling','joint')
