Publishing a research paper
Generally for computer science the accepted methodology is to publish your initial idea or concept with some preliminary results in a conference. Then afterwards if there is still more to discuss you can continue publishing conference papers or target a journal for an in depth publication.

To get started you need to find a conference that suits your area of research. For example if you are working in computer vision you might target CVPR. There are a number of databases full of conferences, which should help you find an appropriate venue. Then read the submission requirements. Usually conferences have a LateX template you can use for your paper.

You should ensure your paper conforms to all conference regulations, has been spell checked and proof read by yourself and someone else.
