I have developed a method that gives similar results (in few cases: better) compared to existing methods and I want to publish it. Can I do this and if yes, how do I motivate it? More specifically:
I am a undergraduate researcher, investigating methods to detect X in images. We have a solution using two images and another method proposed in the literature before also used two images.
Recently we discovered that we can solve the same problem in a very different manner if we use three images (taken differently) and still get similar results. This technique will be based on a particular observation and it is not discussed in the literature. Does it make a good paper given that the problem can be solved using two images with similar results?
How should I write and explain it in my paper about why I am using three images instead of two, because the results obtained are similar? The way in which the three images are taken is different from taking two images and our observation in the three-image-case seems to be novel.
Edit (from comment): In some cases our previously proposed method which uses 2 images gives inaccurate results compared to 3 image solution.
