MATLAB: How to insert a background image into a 3d plot

backgroundimreadimshowuistack

Hi, I'm wondering how to go about inserting a 2d image into the background of a 3d plot, with the inserted image not interfering with the plot. Any advice would be greatly appreciated.

Try something like this

img = imread('peacock.jpg');
ax1 = axes();
imshow(img, 'Parent', ax1);
ax2 = axes('Color', 'none');
ax2.XAxis.LineWidth = 2;
ax2.YAxis.LineWidth = 2;
ax2.ZAxis.LineWidth = 2;
hold on
plot3(rand(1,10), rand(1,10), rand(1,10), 'r', 'LineWidth', 4)
view(3)

Try this

I = imread('cameraman.tif');
BW = edge(I,'canny');
[J,rect2] = imcrop(BW);
[r,c] = find ( BW == 1 );
pP = [c r];
f = figure;
ax = axes;
imshow(I)
hold on
plot(pP(:,1),pP(:,2),'.w','MarkerSize',5)
rectangle('Position',rect2,'EdgeColor','red','LineWidth',3)
frame = getframe(gca);
imwrite(frame.cdata, 'TH.tif')

If you are using R2020a, then MATLAB also introduced exportgraphics

I = imread('cameraman.tif');
BW = edge(I,'canny');
[J,rect2] = imcrop(BW);
[r,c] = find ( BW == 1 );
pP = [c r];
f = figure;
ax = axes;
imshow(I)
hold on
plot(pP(:,1),pP(:,2),'.w','MarkerSize',5)
rectangle('Position',rect2,'EdgeColor','red','LineWidth',3)
exportgraphics(gca,'TH.tif')
