Jd=diffusion(J,method,N,K)
J :待扩散的原图像
method : lin : 线性扩散 (常数 c=1).
pm1 : perona-malik, c=exp{-(|grad(J)|/K)^2}
pm2 : perona-malik, c=1/{1+(|grad(J)|/K)^2}
rmp : 复数
K :边缘门限参数
N :迭代次数
dt:时间步长 (0 < dt <= 0.25, 缺省值为0.2)
sigma2 ：如果有该参数, 则计算与高斯核做卷积的扩散系数的梯度- Jd = diffusion (J, method, N, K) J: to be the spread of the original image method: ' lin' : linear diffusion (constant c = 1). ' Pm1' : perona-malik, c = exp {- (| grad (J) |/K) ^ 2} ' pm2' : perona-malik, c = 1/{1+ (| grad (J) |/K) ^ 2} ' rmp' : the plural K: edge of the threshold parameter N: number of iterations dt: time step (0 < dt < = 0.25, default 0.2) sigma2: If this parameter is calculated to do the convolution with the Gaussian kernel the gradient diffusion coefficient相关搜索： diffusion
