Journal ArticleDOI
Suppression of moiré fringes due to sampling of halftone screened images
TL;DR: In this method, halftone screened images are sampled twice with different sampling rates, and the selection of proper frequency components less suffering from aliasing errors can effectively suppress moire fringes.
Journal ArticleDOI
High‐speed recording of full‐parallax holographic stereograms by a parallel exposure system
TL;DR: A full-parallax holographic stereogram, which is suitable for the holographic 3-D printer (holoprinter), is being developed for the output device of three-dimensional image hard copies of computer data.
Journal ArticleDOI
Compensation of motion blur in CCD color endoscope images
TL;DR: A digital method is proposed for the restoration of images color-shifted by the object motion that makes use of phase-only matching followed by a resampling operation to compensate for a space-variant shift between different primary color images.
Proceedings ArticleDOI
Multispectral image enhancement for H&E stained pathological tissue specimens
TL;DR: It is shown that with multispectral imaging the difference between collagen fiber and smooth muscle can be visualized even from an H&E stained image, a capability compared to the conventional RGB imaging systems to delineate tissue structures with subtle colorimetric difference.
