In addition, module variations between the two eyes can result in different colors being seen with the left and right eyes. Binocular rivalry is expected for large color differences between the two eyes, which can severely affect product usability. Thus, it is important to characterize and predict the binocular rivalry in HMDs caused by interocular color differences. As a step toward this end, we propose the first binocular color difference metric, ΔE*bino, to predict the just noticeable binocular rivalry for a pair of solid colors. A psychophysical experiment was conducted using Meta Quest 2, in which we presented different colors to the left and right eye. The collected data were analyzed to derive the metric using ROC curves. We show that the ΔE*bino metric showed significant improvements over conventional color difference formulae. Both the ΔE*bino formula and the anonymized experiment results are available for download.","PeriodicalId":10459,"journal":{"name":"Color Research and Application","volume":"49 1","pages":"51-64"},"PeriodicalIF":1.4,"publicationDate":"2023-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127096001","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For many years, the innovative urban and architectural experiment inspired and supported by Adriano Olivetti, financed by his company for a large part of the twentieth century, was less well known internationally. His patronage and his far-sighted vision for urban society have produced results of great relevance in the history of Italian industrialization and Modern Architecture. Since 2018, the architectural assets, the archives, cultural heritage and social experiments, have become part of the UNESCO Catalogue of World Heritage Sites (Ivrea, industrial city of the 20th century). Today, many of these heritage buildings, characterized by external surfaces decorated with colored tiles of different types, have several conservation problems, due in many cases to the lack of ordinary maintenance. At the same time, the unavailability of original materials makes the planning of appropriate intervention solutions for maintenance and restoration difficult. This report intends to give an account of this event through two convergent approaches: (i) on the level of method, continually seeking a precise analysis of the materials, trying to refrain from the image of an ‘Olivetti's architecture’ flattened only on rationalist models—chromatically limited—to do justice to a less minimalist vision that has characterized the architectural heritage on matter since its inception; (ii) on the operative level, giving an account of the attempts to recover and restore that “world of colours” that is the Olivetti's city, also with a correct lexical reading of the architectural elements and the finding of materials (an operation declined toward “what can be done today”, given that many original products are unavailable and manufacturers are no longer in activity).","PeriodicalId":10459,"journal":{"name":"Color Research and Application","volume":"49 1","pages":"144-162"},"PeriodicalIF":1.4,"publicationDate":"2023-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122445509","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, medical images taken by operators with different skill levels have a considerable variation in visual quality. Poor illumination of images increases uncertainty in clinical treatment and lead to the risk of misdiagnosis. This paper proposes a novel bilateral tone-mapped gamma correction to enhance the visual quality of medical images without affecting the natural color quality. First, the proposed tone-mapped gamma correction is employed to enhance the intensity values of poorly illuminated medical images. Then, bilateral enhancement curve adjustment is performed to effectively improve the global luminance content of the input image with features and richer information. The image quality assessment measures like entropy, blind/reference less image spatial quality evaluator, natural image quality evaluator, perception-based image quality evaluator, contrast enhancement based image quality parameter, and color contrast fog density evaluates the superior performance of the proposed technique. The experimental results significantly enhance the intensity difference between dark and bright areas and can aid clinical experts and intelligent health fields.","PeriodicalId":10459,"journal":{"name":"Color Research and Application","volume":"48 6","pages":"748-760"},"PeriodicalIF":1.4,"publicationDate":"2023-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50126687","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper reviews various approaches to using color on buildings: for example, the evolution of regional styles due to the availability of pigments and materials, the use of color as a form of decorative drapery, and the emphasis of a building's pure form without any additional color. Central to the paper is the analysis of the dichotomy between the reality of the process of actually experiencing a city and its buildings on the one hand and the design process on the other—a dichotomy between reception and production, thus, a contradiction between an “atmospheric world” of human perception and cognition and a professional world of imaginative design, in which the spatial atmosphere created by color, material, and light often emerges only as a by-product at the end of a conceptual and diagrammatic planning process. The paper proposes a different way of going about the architectural design process that encompasses holistic thinking in color, material, and light right from the start.","PeriodicalId":10459,"journal":{"name":"Color Research and Application","volume":"48 5","pages":"543-556"},"PeriodicalIF":1.4,"publicationDate":"2023-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/col.22876","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50118801","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
