this code is between tow image i need between image and video
points1 = detectHarrisFeatures(I);
points2 = detectHarrisFeatures(F);
[features1, valid_points1] = extractFeatures(I, points1);
[features2, valid_points2] = extractFeatures(F, points2);
indexPairs = matchFeatures(features1, features2);
matched_points1 = valid_points1(indexPairs(:, 1), :);
matched_points2 = valid_points2(indexPairs(:, 2), :);
figure; showMatchedFeatures(I, frame, matched_points1, matched_points2);

It is not possible to work directly with videos. Instead, you have to read (or capture) a frame of the video at a time. The frame of the video is an image, so you can just assign that image to the appropriate variable name and use your existing code.
