  1. Read relevant material for Chamfer system [5], hierarchical object detection [9], assembly techniques [1, 3, 8], and survey material [6].
  2. Download and install OpenCV library [2]. Get familiar with the programming with the library [10].
  3. Practice usage of part detectors. Run simple tests on several images. Make a module that can be later integrated with the aggregated algorithm
  4. Develop (very simple) labeling application. The application should load a series of images (e.g. all *.ppm files from a given folder), present a GUI that allows a user to draw rectangles, and save parameters of the rectangles. For each image: number and coordinates of all rectangles in a text of Matlab file.
  5. Label around 200 images (2 minutes/image x 200 images = 7 hours = 3 days x 2.5 hours/day). It is recommended that this step is performed quite early in the pro ject, since the evaluation of detectors requires labeled images.
  6. Given labeled images, test individual detectors in a systematic setup (ROC curves)
  7. Design/implement/test assembly algorithm (Several versions are welcome).
    • Start simple. Use the evaluation results of part detectors to decide which parts are most reliable.
    • Think of constraints on distance and size of one part relative to the other.
    • Think of color (appearance) similarities between body parts.
    • See [1, 8, 7] for inspiration.
  8. Perform systematic tests on labeled images. Compare results with individual detectors. Compare processing time.
  9. Write paper, prepare a presentation.
