Great efforts have been made to develop color appearance models to predict color appearance of stimuli under various viewing conditions. CIECAM02, the most widely used color appearance model, and many other color appearance models were all developed based on corresponding color datasets, including LUTCHI data. Though the effect of adapting light level on color appearance, which is known as "Hunt Effect", is well known, most of the corresponding color datasets were collected within a limited range of light levels (i.e., below 700 cd/m2), which was much lower than that under daylight. A recent study investigating color preference of an artwork under various light levels from 20 to 15000 lx suggested that the existing color appearance models may not accurately characterize the color appearance of stimuli under extremely high light levels, based on the assumption that the same preference judgements were due to the same color appearance. This article reports a psychophysical study, which was designed to directly collect corresponding colors under two light levels— 100 and 3000 cd/m2 (i.e., ≈ 314 and 9420 lx). Human observers completed haploscopic color matching for four color stimuli (i.e., red, green, blue, and yellow) under the two light levels at 2700 or 6500 K. Though the Hunt Effect was supported by the results, CIECAM02 was found to have large errors under the extremely high light levels, especially when the CCT was low.

Visual effect adalah bagian yang penting dalam pembuatan film ataupun animasi sebagai salah satu faktor pendukung dalam membangun emosi cerita. Visual effect yang baik dapat diciptakan dengan berbagai cara yang sederhana hingga cara yang rumit dengan melibatkan berbagai teknik gabungan software atau plugin dan juga menggunakan komputer dengan kemampuan tinggi. Dalam pengaplikasiannya di animasi pendek 3D tanpa dialog berjudul Little Kites Story, visual effect digunakan sebagai sarana penyampaian emosi dan memperkuat penggambaran sebuah suasana yang tenang dan damai. Visual effect yang diaplikasikan akan dibuat dengan memaksimalkan kemampuan komputer pada industri kecil atau industri rumahan. Keywords : visual effect, industri rumahan, penyampaian emosi, penggambaran suasana, efisiensi

Visual Effect can be used to enhance storytelling in the filmmaking process. The Visual Effects technology itself already has grown to become faster and better in production. However, in the Visual Effects Department, the artist needs digital props to show what’s on the screen. Therefore, this study seeks to create props for Visual Effects needs. This present study describes how to create believable props for visual effects needs in a short film called “Mie Medan”. It concludes that to create a visual effect props, we have to consider to create real-scale and proportion in each set and props to gain believability in film, the hue, and saturation of the color and texture itself will gain more realistic and sense of flavor to the film.

AbstrakKarya ini sebenarnya adalah sebuah eksperimen, sebuah eksplorasi atas kemungkinan-kemungkinan penerapan motif jumputanbiru pada permukaan keramik. Proses ini bagaimana sebuah penjelajahan tanpa akhir yang hasil-hasilnya menawarkan secaravisual ruang untuk berimajinasi yang selalu penuh dengan kejutan yang dihasilkan dari ikatan, lipatan, kerutan, jelujur, danpewarnaan. Warna dan motif pada kain shibori biru dan pada keramik warna biru cobalt memiliki persamaa yang dekat dalamhal warna. Kesamaan ini dipandang sebagai representasi shibori biru yang diterapkan pada tekstil. Efek visual memunculkanspirit jumputan biru pada keramik yang tidak lagi mengacu pada pemaknaan yang ada pada kain jumputan biru.AbstractThe work I have completed is basically an experiment, an exploration of the possibilities applying blue shibori motif on ceramicsurface. This process is like a never-ending exploration of which the results visually offer space to have imaginations, alwaysfull of surprises resulting from the process of knotting, folding, wrinkling, stitching and coloring. The color and motif on blueshibori cloth and on cobalt blue ceramic have close similarity in color. This similarity is regarded as the representation of blueshibori as applied on textile. The visual effect of this process brings out the spirit of blue shibori on ceramic, which does notrefer to the meaning existing in the blue shibori cloth.

BACKGROUND Background: Nowadays, the application of computer technology in the medical field is more and more extensive, and many diseases can achieve better diagnosis and treatment effects through computer technology. OBJECTIVE Objective: The paper applies intelligent facial dynamic image information to the clinical treatment of peripheral acupuncture and moxibustion for the treatment of peripheral facial paralysis. An automatic acupoint positioning algorithm based on facial information dynamic image is proposed, which provides an objective and standard basis for the treatment of facial acupuncture and moxibustion. METHODS Methods: The paper selects the head threshold, that is, the facial dynamic image information as the research background, and divides the facial features according to the "three courts and five eyes" rule, and uses the Minimum Eigenvalue operator to detect the corner points of the facial features, locate the facial features, and use the face. The feature position is used as a reference coordinate for facial acupoint positioning. RESULTS Results: After verification, it was found that the positioning was accurate, and the peripheral facial paralysis of the patient was improved after warm acupuncture point positioning treatment, which improved the facial nerve function of the patient, improved the treatment efficiency and shortened the treatment time. Therefore, this technology is worthy of clinical promotion. CONCLUSIONS Conclusion: Through experimental analysis, the algorithm is proved to be effective and accurate. Based on facial dynamic image information to locate acupoints, warm acupuncture has a significant effect on peripheral facial paralysis, which can significantly improve facial nerve function and shorten treatment time, which is worthy of clinical promotion.
