gain function
2.The high effective moistening elements of Ceramide and HA etc. penetrate the depth of pores, reaching cutis layer, activating cells, enabling dry skin to re-gain the function of water and nutrition storage, supplying the skin with enough water and nutrition, in the meantime, forming a biological water-locking film in the surface of skin, stably tenderizing skin with water for 24 hours.
3.In this paper,a thinning-like (TL) property of cellular neural networks(CNN)with opposite-sign templates and a non-unity gain output function is discovered and proved. An image thinning algorithm is realized by a multi-layer CNN,which operates with the TL property,with four local logic units (LLU). An image edge detection is achieved by another parallel CNN with a LLU.
