This is a generic template for a project page. Project pages describe the projects going on at the AIRLab and are listed in the [[Projects]] page. Feel free to copy (but ''not'' to cut or modify) the contents of its 'edit' tab and re-use them as a basis for your own project's page. The instructions to do that are given at [[Projects#HOWTO add a new project to the AIRWiki]].
 
 
Of course this is only intended as a hint: ''your'' page must contain also all the details about your work. In particulat you need to write down in detail if your work can cause any risk to you or to others.

Part 1: project profile

Project name

Nonphotorealistic Rendering of Speed Lines

Project short description

The aim of this project is to experiment some new techniques for syntesizing speed lines from video.

Given a video with a moving object (a person, or something else), we will be able to draw some lines on the last video frame which should convey the object motion in the previous k frames. Beside we will be also able to draw some lines during the video reproduction.

Part 2: project description

The aim of this project is to experiment using some new techniques for syntesizing speed lines from video.

Given a video with a moving object (a person, or something else), we will be able to draw some lines on the last video frame which should convey the object motion in the previous k frames. Beside we will be also able to draw some lines during the video reproduction.

Approach

In order to solve the problem we followed these tasks:

1. We synthesized different videos with a clear separation between a moving foreground and background using blender.

2. We studied how to analyzing video in matlab. In particular we learned how to access and analyze single video's frames.

3. We implemented three different techniques in order to obtain speed-lines.

The Implemented techniques are: Envelope Speed-Lines, Replication Of Contours, Harris Corners Speed-lines. We developed a simple matlab GUI in order to experiment with different parameters within a video.
