FLAMINGO Freeware Download - An automatic counter for aerial images of large bird aggregations
Summary

FLAMINGO aims at detecting and counting flamingos (or any other bird species or object) on any kind of images.

We use a stochastic approach based on a marked point process of ellipses. Each ellipse represents one flamingo. The optimization of the model is performed by a new fast birth-and-death dynamics. This leads to the total number of flamingos.

The program was developed in C++ and uses an additional C++ library, the CImg library developed by D.Tschumperle under a CeCILL licence. This library can be downloaded on http://cimg.sourceforge.net/download.shtml.

Utilization - Windows

In the window version parameters input is straightforward through the GUI.

1. Open an input image. Usable formats are png and jpeg.

2. adjust the min and max size (in pixel) of the small and large axis of the ellipse.

3. Possibly change optional parameters:
The unique type of contrast in the image: 0 for dark objects on bright background or 1 for bright objects on dark background.
The birth rate that is initially fixed to 1. But, if you observe missing detection, you should increase the birth rate to, for example, 2.
The last parameter is the number of iterations of the birth-and-death dynamics. You should leave it to 2000.

4. Run.
A window open and let you draw the area of the image you want to count (clic left to start drawing).
Once you close the window, the program starts counting.


Utilization - Linux

For the linux version you have to modify the parameter file depending on the image.

1. The two first parameters refer to the input image to be analyzed and the output image after the detection where we can see ellipses placed on flamingos.

2. The following three parameters refer to the size of the flamingos searched on the image. The first represents the minimal semi-axe of the ellipses. The second is the pixel freedom of the great semi-axe (from the minimal semi-axe) and the third is the freedom of the small semi-axe (from the minimal semi-axe).

3. Possibly change optional parameters
- the unique type of contrast in the image: 0 for dark objects on bright background or 1 for bright objects on dark background.
- the birth rate that is initially fixed to 1. But, if you observe missing detection, you should increase the birth rate to, for example, 2.
- The last parameter is the number of iterations of the birth-and-death dynamics. You should leave it to 2000.
