How to detect and track object as a input in ( ARkit ) octave ? - machine-learning

Question

In my AR project i have to detect a input as object ???
I tried one code in Octave platform but shows error as
error: 'detectSURFFeatures' undefined near line 10 column 14
error: called from
plz at line 10 column 13
I installed the image acquisition package and image package then also converted color image to grayscale image using rgb2gray()
But I cant install the computer vision system tool in octave
How to install that tool on octave ?could you please help me to resolve that problem
This is my coding .........
referenceImage=imread('l.jpg');
figure(1)
imshow(referenceImage);
referenceImageGray = rgb2gray(referenceImage);
figure(2)
imshow(referenceImageGray);
referencePts=detectSURFFeatures(referenceImageGray);
referenceFeatures=extractFeatures(referenceImageGray,referencePts);
figure;
imshow(referenceImage), hold on;
plot(referencePts.selectStrongest(50));
video= vision.VideoFileReader('nothing.mp4','VideoOutputDataType','uint8');
for k=1:30
step(video);
end
