  • Most commercial digital still cameras use a single sensor array (e.g., CMOS or CCD) with color filter array (CFA) to reduce the cost and size. Since the image obtained with CFA has only one color value per pixel, the demosaicing is needed to acquire missing two color values. Although many demosaicing methods have been proposed, they still have artifacts such as rainbow and zippering artifact. In this paper, we propose the simple demosaicing algorithm using tendency of neighbor pixels with the enhanced weighting function. In the experimental results, our algorithm shows much better subjective qualities of the images than conventional demosaicing algorithm and improves objective qualities.

  • Astaxanthin is a valuable pigment source for many aquacultured species, including salmonoids, shrimp, sea bream, and ornamental species. Conjugated linoleic acid (CLA) and ascidian tunic extracts were mixed with the basal diet of rainbow trout to investigate their pigmentation effects. Synthetic Carophyll Pink and natural carotenoids that came from the tunic extracts were incorporated into muscle and skin tissues. The main carotenoids found in muscle after 8 weeks were canthaxanthin in CP12 (13.4%), and CP52 (17.2%), and astaxanthin in CP12 (58.5%), and CP52 (59.2%) in the Carophyll Pink group, while those in skin were canthaxanthin in CP14 (34.5%), and CP54 (29.2%), and astaxanthin in CP14 (32.0%), and CP54 (36.5%) in the ascidian tunic extract group. The total carotenoid content in skin (53.0-69.3 mg/kg) was greater than that in muscle (9.5-13.8 mg/kg).

  • This study was carried out to make the new products of color moot as a functional food by variation of the color and flavor through addition of gamgyul, Daccus Carota Var. Sativa, Vitis vinifera, soy sauce, and Pimpinella brachycarpa N., respectively. For all the products, the color was observed by Colorimeter and the sensory evaluation was performed to evaluate their effectiveness and usefulness. The A$_w$ (water activity) test of color mooks has performed to examine their water activity individually. The A$_w$ of color moot was higher than that of the white one. The characters of texture of color mook as a function of the amount of the color and the flavor added were measured by a texture analyzer (XT-RA, Texturometer). By the TPA test, the rainbow and orange color mook examined were high in the springiness.

  • This study compared the food quality of domesticated(RT-DS) and freshwater (RT-F) rainbow trouts Oncorhynchus mykiss. The proximate composition of RT-DS was 73.8% moisture, 20.6% crude protein, 4.2% crude lipid, and 1.1% ash and was similar to RT-F. No differences were found in the red color, odor and taste intensities, calcium, and potassium between RT-DS and RT-F based on the Hunter a values, volatile basic nitrogen content, odor intensity and using an electronic nose, and taste intensity using an electronic tongue. The crude protein, total amino acid contents, and taurine, glutamic acid, glycine, alanine and anserine contents in free amino acids were higher in RT-DS than in RT-F. There was no difference in hardness between RT-DS and RT-F.

  • Recently, as the prepress mainstream is changed to the digital workflow, various digital proofing systems such as high price dye sublimation printers and low price ink jet printers are widely used in printing industry. However, most of the digital proofing devices have lower resolution than analog proofing systems and differ with actual color presses in the color gamuts. Therefore, proper color compensations are needed for digital color proofing in order to match colors between the proofs and the press sheets. This study shows the application method of Look-up Table to the digital color proofer of Rainbow, the analog proofer of Matchprint-II, and an actual offset press is effective on the color compensations.

  • Natural dyeing is considered to be an alternative to chemical staining in terms of harmful VOC-free and environmentally-friendly ingredient. This study was concerned with an evaluation of color performance of naturally dyed- and painted veneer for cylindrical laminated veneer lumber etc. according to the used condition in terms of existence of light and heat in drying. From the results, the color changes by the color of dyed veneer and the type of paint are likely to be affected by fading condition of light or heat. In the future, long-term outdoor exposure test needs to be additionally followed in order to evaluate durable usability of colored veneers.

  • The wood veneers were clearly rainbow-colored with natural dyes. As shown through Korean-style jacket with stripes of multi-colors beyond traditional obang colors (red, blue, yellow, black and white colors), eco-friendly coloring methods representing Korean colors familiar from old times could be used nobly by coloring natural wood veneer being raw material of wood products. In terms of industrialization, the study to manifest korean color, substituting chemical stains such as dye and pigment, would be necessary. In order to realize this purpose, the study about economical dyeing materials and characteristics, that is, mordant, dyeing and drying techniques showing environment-friendly coloring and high coloration level ought to be followed. In addition to this, investigating discoloration transition by fading test for interior and exterior uses would have to be carried out.

  • This study investigated the sensory characteristics (texture, odor, taste and color) of jerky produced from ground sea rainbow trout (SRT) Oncorhynchus mykiss frame muscle (FM). The hardness of the ground SRT-FM jerky was 453.9±91.0 g/cm2, which was lower than that of commercial animal jerky (893.5±404.6 g/cm2) and commercial fish jerky (1,394.4±363.5 g/cm2). The difference in the hardness values of the ground SRT-FM jerky and commercial animal jerky was not significant. The volatile basic nitrogen content of the ground SRT-FM jerky was 48.3±1.6 mg/100 g, which was higher than that of commercial fish jerky (21.6±6.2 mg/100 g) and commercial animal jerky (18.2±6.3 mg/100 g). However, the fish odor of the ground SRT-FM jerky was masked by the presence of various additives. The hydrophilic and lipophilic browning indices of the ground SRT-FM jerky were higher than those of the commercial jerky. The total taste value of the ground SRT-FM jerky was 169.0, and the major amino acids were glutamic acid and aspartic acid. These results suggest that ground SRT-FM jerky would be acceptable to consumers.

  • A new Cymbidium cultivar 'White Princess' was released by the National Horticultural Research Institute (NHRI) in 2005. A cross was made in 1995 between 'Cymbidium 2113', light purple colored petal and medium plant sized variety, and 'Lucky Rainbow Randevous', a dark purple petal with red lip and large type variety. The ninety progenies were obtained after planting and acclimatization in green house. In 2000, a line (9526747) was selected and multipliticed after test of its flower color, leaf shape, flower stalk, and vigorous growing habit. After evaluation trial for two growing seasons, the selected line was named as 'White Princess'. The 'White Princess' has white petals (WN 155A) with red lip (RP59D) color and large sized leaves, and flowers (leaf length is about 88 cm and flower diameter is about 8 cm) with semi-erect flower stalks. Blooming started from December to January in optimal culture conditions. High temperature (more than $30^{\circ}C$) and low light intensity(less than 10,000Lux) should be avoided for the appropriate growth.
