# Readme file for The Flutter Shutter Code Calculator. Basic use :

Use script_uniform.sh or script_gaussian.sh to reproduce the
examples presented in the paper. It compiles and run the program with adequate
parameters.

# ABOUT

* Author  : This software was written by Yohann Tendero <tendero@math.ucla.edu>



#TO REPRODUCE THE EXAMPLES OF THE PAPER
One can use one of the 2 shell scripts. The commands are 
./script_gaussian (for the truncated Gaussian experiments)
./script_uniform (for the uniform motion model)

THESE SCRIPTS NEED GNUPLOT TO PROCUDE THE PLOTS.

# OVERVIEW

This source code provides in implementation of the algorithm described in
"The Flutter Shutter Code Calculator" (IPOL)

* the executable file is flutter_optimizer

This program writes text files.

- Compilation.
Automated compilation requires the make program.



# COMPILATION
1. Download the code package and extract it. Go to that directory.

2. Compile the source code (on Unix/Linux/Mac OS).
Run make


# USAGE

'flutter_optimizer' takes 8 or 9 parameters:
`flutter_optimizer flag_motion_model motion_model_param_1 code_length exposure_time_factor code_file_name Fourier_transform_file_name efficency_file_name  efficency_risk_file_name`

* flag_motion_model: 0: (truncated) Gaussian or 1 uniform motion model
* Gaussian standard-deviation, or range, or v_{max}.
* code_length: L the length of the code.
* exposure_time_factor: $c$ parameter, control the support of the flutter shutter function.
* code_file_name: name of the text file to write the code coefficients $\alpha_k$
* Fourier_transform_file_name: name of the text file to write the code Fourier transform of the code
* efficency_file_name: name of the text file to write the efficiency $R(v)$ function
* efficency_risk_file_name: name of the text file to write the average efficency and the risk.

example : ./flutter_optimizer 0 0.25  52 5  code.txt TF_code.txt rendement.txt mean_sdt.txt
