Defocus-aware Dirichlet Particle Filter (D-DPF)

This program includes Dirichlet Particle filter[1, 2] and Defocus-aware Dirichlet Particle Filter[2].

For parameter estimation of Dirichlet distribution, Dirichlet MLE python library is used. Greatly thanks to his work. Note that this parameter estimation is different to ones written in the paper [2].

Execution environment

• OS: Mac OS X (10.11)
• Language: Python 2.7 (Anaconda 2.4.*)
• Modules: Numpy, Scipy, Matplotlib

Usage

python ./main.py
