What was needed was Heron's regula, a counter signal to rein in the chief signal, to dampen the effect of the perpetual recycling. 所以，這里就需要某種類(lèi)似于海倫的調節裝置的東西，能夠產(chǎn)生抑制主信號的反向信號，減弱不斷重復的循環(huán)所帶來(lái)的影響。
A multi-kernel nonlinear diffusion model for image denoising based on image decomposition was studied, which got the major signal and the minutiae through different models. 摘要研究了一種基于圖像分解的多核非線(xiàn)性擴散去噪方法，利用兩個(gè)非線(xiàn)性擴散模型分別提取圖像的主信號和細節信息。
