Bottleneck-type Neural Net Architecture for Image Compression for laboratory work.

Armadillo C++ linear algebra library

The CImg Library for image processing

for Ubuntu:

sudo apt-get install libarmadillo-dev libarmadillo6
sudo apt-get install cimg-dev

Before installing Armadillo, it's recommended to install LAPACK, BLAS and ATLAS

n – height of rectangle;

m – width of rectangle;

p – number of neuron for second layer;

e – error degree;

α – learning step;

argv[1] - path to image

Z – compression ratio;

Iteration – number of iterations;

E – total error for the training sample;
