Idea : design and implement a method to convey information on an audio stream using steganography with the use of convex orthogonal demixing.

Objectives :

  • design orthogonal frames for payload insertion (both in the Fourier and Gabor domains)
  • achieve message retrieval by convex demixing
  • study of the influence of the mixing parameters in a analog-to-digital noisy channel

Skills required :

  • Programming (Matlab)
  • Notions of Convex Optimization
