Communications to the Editor ticed for days with a laryngeal mirror until he was able to tolerate the examination without a topical anesthetic. Indeed, using a lightbulb, head mirror, wall mirror and laryngeal mirror, he learned how to visualize his own larynx. When the next opportunity arose, Mr. Brubaker again volunteered to sit for the photography session, this time without a topical anesthe...

We report retinal structural changes of a 37-year-old man diagnosed with the concomitant occlusion of cilioretinal artery and central retinal vein. Comprehensive ophthalmological evaluation was performed, followed by spectral-domain optical coherence tomography (SD-OCT, Heidelberg), optical coherence tomography angiography (OCT angiography, Optovue Inc., Fremont, California, USA), fluorescein a...

In this paper, we present an approach to a pipeline for time lapse photography using conventional digital images converted to HDR (High Dynamic Range) images (rather than conventional digital or film exposures). Using this method, it is possible to capture a greater level of detail and a different look than one would get from a conventional time lapse image sequence. With HDR images properly to...

Significance Gabriel Lippmann won the 1908 Nobel Prize in Physics for his method of reproducing colors photography. Despite significance this result, there are still misconceptions regarding approach. We provide a complete end-to-end analysis process and show, both theoretically experimentally, how spectrum reflected from plate is not same as exposing spectrum. In addition, we demonstrate that,...

Color correction techniques in digital photography often rely on the use of color charts, which require including this relatively large object field view. We propose here to QR Codes pack these charts a compact form factor, fully compatible manner with conventional black and white Codes; is, without losing any their easy location, sampling data storage features. First, we present an algorithm b...

The present work intends to focus on the examination, analysis and treatment of Pace, a contemporary color photography experimental artwork created by Nino Migliori in 1973. Given particular nature artifact, which photographic materials media art coexist complex interaction, an in-depth study its creation, structure components was deemed necessary plan perform adequate conservation treatment. p...

デジタル画像システムで鉄さびの面積算出を行うのに，二値化画像データを用いる方法が一般的である．しかし鉄さびには赤さびの他，黒い腐食生成物等が有り，二値化データを使用することは不適切な場合がある．そこでsRGBの24ビットカラー画像での評価を試みた．小面積の鉄さび像の赤さび・黒腐食生成物・金属下地の面積を目視で判定し教師データを作り，サポートベクターマシンを用いて評価した．その結果，画像を各領域に分割し，面積および面積率を算出できた．

We tested the camouflage hypothesis, or the linkage between animal (Saharan rodent) and habitat coloration, on the largest geographical scale yet conducted. We aimed to determine whether phenotypic variation is explained by micro-habitat variation and/or genetic polymorphism to determine 1) the strength of linkage between fur color and local substrate color, and 2) the divergence in fur colorat...
