i’m Nur Anis study on a research about the classification of satellite image(Landsat 8 Image) using Artificial Neural Network.
I don’t know how to extract the features from the images in matlab to I continue train and classify the image into five classes.
If you don't have pure background then you will end up with more and false keypoints. MK-RoD is prone to false SIFT keypoint matches. So simply, the algorithm will not work if you use background.
Hi Caglar, you have done a great work, I have a question. Why is it recommendable to use a pure black background? I mean, what happens with the algorithm and the keypoints if you don´t have that background?
