4)impulse extension脉冲扩展
5)pulse broadening脉冲扩宽
6)shock-diffusion冲击扩散
1.A shock-diffusion equation with local coupling term is presented,where an inverse diffusion(shock)is performed to sharpen edges along the normal directions to the isophote lines(edges),while a normal diffusion is done to remove noise and artifacts(“jag-gies”)along the tangent directions on the contrary.提出了带有局部耦合项的冲击扩散方程,其沿着等照度线(边缘)的梯度方向实施反向扩散(冲击)以锐化边缘;相反地沿切线方向实施正向扩散以去除噪声和锯齿伪像。
