I have used this code of HOG (Histogram of gradient) for clustering the text-images. I have got the row vector 1x1440 . How can i pass it into k mean clustering algorithm for clustering.

img = imread('1.jpg');
[featureVector,hogVisualization] = extractHOGFeatures(img);

Here, my k-mean clustering code: I cannot pass a complete feature vector as one feature(single value).

inputFeature = featorvector;
[cidx2,extra] = kmeans(inputFeature,2);

Here is image 1.jpg :

Please post a sample image, answering a question is always easier if we can run your code. – m7913d Mar 13 '17 at 10:54
