In this thesis studies on accurate surface color measurements are considered. Errors in a spectrophotometric measurements are discussed and correction methods introduced. The wavelength interval in a tristimulus integration is considered next. The ASTM weighting functions are tested with a large data set of non fluorescent colors and shown to be useless. The thermochromic effect is also discuss...

Among the hyphomycetous endoparasites destructive to eelworms that abound in slowly decaying plant materials, as well as in agar plate cultures earlier inoculated with partly decomposed vegetable detritus, Harposporium anguillulae Lohde emend. Zopf (1888) is observed much more frequently than allied forms. In seeking an explanation for this more frequent occurrence it would seem highly signific...

This paper describes a physiologically based toxicokinetic model for 1,3-butadiene uptake, distribution, and metabolic clearance in mice. Model parameters for metabolic activity were estimated from the correspondence between computer simulation studies and experimental results as published in the literature. The parameterized model was validated with independent literature data. With the result...

A variety of multi-spectral imaging methods are discussed for acquiring spectral information from a scene. We first review conventional multispectral imaging approach. The conventional imaging systems are mostly constructed by multi-band imaging devices with different filtration mechanism at the sensor side under passive illumination. We show some imaging devices, estimation algorithms, and app...

Port-wine stain (PWS) birthmarks are one class of benign congenital vascular malformation. Laser therapy is the most successful treatment modality of PWS. Unfortunately, this approach has limited efficacy, with only 10% of patients experiencing complete blanching of the PWS. To address this problem, several research groups have developed technologies and methods designed to study treatment outc...

– For large scale satellite images, it is evitable that images will be affected by various uncertain factors, especially those from atmosphere. To minimize the impact of atmosphere medium dispersing, image segmentation is an essential procedure. As one of the most critical means of image processing and data analysis approach, segmentation is to classify an image into parts that have a strong co...

Pulsed photothermal radiometry (PPTR) enables noninvasive determination of temperature depth profiles induced in strongly scattering biological tissues and organs, including human skin, by pulsed laser irradiation. In the present study, we evaluate the potential of this technique for objective characterization of a laser tattoo removal procedure. The study involved 5 healthy volunteers (age 20–...

This paper proposes a color decomposition method for a multi-primary display (MPD) using a 3-dimensional look-uptable (3D-LUT) in linearized LAB space. The proposed method decomposes the conventional three primary colors into multi-primary control values for a display device under the constraints of tristimulus matching. To reproduce images on an MPD, the color signals are estimated from a devi...
