Multispectral image visualization through first-order fusionIEEE Transactions on Image Processing - Tập 11 Số 8 - Trang 923-931 - 2002

We present a new formalism for the treatment and understanding of multispectral images and multisensor imagery based on first-order contrast information. Although little attention has been paid to the utility of multispectral contrast, we develop a theory for multispectral contrast that enables us to produce an optimal grayscale visualization of the first-order contrast of an image with an arbitra...... hiện toàn bộ

A joint estimation approach for two-tone image deblurring by blind deconvolutionIEEE Transactions on Image Processing - Tập 11 Số 8 - Trang 847-858 - 2002
Ta-Hsin Li, Keh-Shin Lii
A new statistical method is proposed for deblurring two-tone images, i.e., images with two unknown grey levels, that are blurred by an unknown linear filter. The key idea of the proposed method is to adjust a deblurring filter until its output becomes two tone. Two optimization criteria are proposed for the adjustment of the deblurring filter. A three-step iterative algorithm (TSIA) is also propos...... hiện toàn bộ
