Implementing SIFT in Java

Question

So I\'m working on a simple Java app that allows a user to input an image as a query and have the app compare it against a database of images (which is basically no more tha

This tutorial in openimaj shows a step by step procedure on how to use SIFT from OpenImaj library.

However, If you need to the java implementation, as the tutorial says,

We’ll use the difference-of-Gaussian feature detector which we describe with a SIFT descriptor. The features we find are described in a way which makes them invariant to size changes, rotation and position. These are quite powerful features and are used in a variety of tasks. The standard implementation of SIFT in OpenIMAJ can be found in the DoGSIFTEngine class:

The API method reference for the "DoGSIFTEngine" can be found by going through the following link.

Here is the link to the full implementation
