I have to extract features of an image using the image extraction from MATLAB. It works successfully with the image provided by The MathWorks in their tutorial, but when I enter another image it doesn't work
My code for image extraction is:
boxImage = imread('stapleRemover.jpg');
%boxImage = imread('D:\matlab test\book\IMG_2294.jpg');
figure;
imshow(boxImage);
title('Image of a Box');
%sceneImage = imread('D:\matlab test\book\IMG_2291.jpg');
sceneImage = imread('clutteredDesk.jpg');
figure;
imshow(sceneImage);
title('Image of Cluttered Scene');
%detecting feature point
boxPoints = detectSURFFeatures(boxImage);
scenePoints = detectSURFFeatures(sceneImage);
figure;
imshow(boxImage);
title('100 strongest feature Points from Box Image');
hold on;
plot(selectStrongest(boxPoints, 100));
figure;
imshow(sceneImage);
title('300 Strongest Feature Points from Scene Image');
hold on;
plot(selectStrongest(scenePoints, 300));
%extracting feature descriptor
[boxFeatures, boxPoints] = extractFeatures(boxImage, boxPoints);
[sceneFeatures, scenePoints] = extractFeatures(sceneImage, scenePoints);
%finding putative point match
boxPairs = matchFeatures(boxFeatures, sceneFeatures);
matchedBoxPoints = boxPoints(boxPairs(:, 1), :);
matchedScenePoints = scenePoints(boxPairs(:, 2), :);
figure;
showMatchedFeatures(boxImage, sceneImage, matchedBoxPoints, matchedScenePoints, 'montage');
title('Putatively Matched Points (Including Outliers)');
%locating object in the scene using putative matches
[tform, inlierBoxPoints, inlierScenePoints] = estimateGeometricTransform(matchedBoxPoints, matchedScenePoints, 'affine');
figure;
showMatchedFeatures(boxImage, sceneImage, inlierBoxPoints,inlierScenePoints, 'montage');
title('Matched Points (Inliers Only)');
boxPolygon = [1, 1; % top-left
size(boxImage, 2), 1; % top-right
size(boxImage, 2), size(boxImage, 1); % bottom-right
1, size(boxImage, 1); % bottom-left
1, 1]; % top-left again to close the polygon
newBoxPolygon = transformPointsForward(tform, boxPolygon);
figure;
imshow(boxPolygon);
imshow(sceneImage);
hold on;
line(newBoxPolygon(:, 1), newBoxPolygon(:, 2), 'Color', 'y');
title('Detected Box');
It runs successfully, but when I change the image which is made by me using my camera, it stops executing code on this line:
boxPoints = detectSURFFeatures(boxImage);
Can anyone help me to out?
