How can I merge image points extracted from extractFeatures function into the original image?

Hi everyone!
I just extracted surfPoints with the extractFeatures function
[imagesFeatures{i}, imagesPoints{i}] = extractFeatures(imGray, detectSURFFeatures(imGray));
I know I can plot the surf extracted points with the plot function
figure(1); imshow(images{1}); hold on;
plot(imagesPoints{1}.selectStrongest(10),'showOrientation',true);
However I would like to merge the points and the original image into a single image. That is because I want to show all the features of my dataset of images with the montage function.
Thank you so much,
Marcos

Hi,
Run the below sample code in loop for the dataset and montage over the saved images
I = imread('cameraman.tif');
points = detectSURFFeatures(I);
[features, valid_points] = extractFeatures(I, points);
f = figure;
imshow(I); hold on;
plot(valid_points.selectStrongest(10),'showOrientation',true);
saveas(f,'Result.png')
Hope this helps
