Feedback model inspired by biological development to hierarchically design complex structure

We propose a new feedback system, the BiDevelopment System-inspired by the development mechanism of Drosophila-and discuss possible computer graphics and data compression applications. Drosophila´s development forms complex organs from a fertilized egg by hierarchically diffusing different protein densities roughly among cells during the earlier stages and minutely during the later stages. The proposed system models this mechanism and realizes a hierarchical rough-to-detailed or simple-to-complex design, and vice versa. Unlike many conventional feedback systems, it is possible to embed our intended rough design into the mechanism, which is the most significant feature of the proposed system. We compare the BiDevelopment System to biological development with analogies, explain two example algorithms, create complex images from a simple seed code, and discuss its opposite application, data compression
