中文摘要: |
线性最小均方误差估计LMMSE(wavelet-based multiscale linear minimum mean squareerror estimation)目前是小波去噪领域的热门课题,讨论了矢量空间的最小均方误差估计的新算法,主要考虑图像各层间的关系,将线性MMSE运用到矢量空间,对去噪图像边缘模糊问题有较大改善。 |
英文摘要: |
Linear minimum mean square error estimation-LMMSE(wavelet-based multiscale linear minimum mean square-error estimation) is currently a hot topic of wavelet denoising field.Vector space discussed below is the minimum mean square error estimation of the new algorithm.Considering the image more the relationship between layers and the linear MMSE applied to the vector space,blurring the edges of the image denoising have been greatly improved. |
