History The 63rd page of the Book of Hours (Use of Utrecht), c. Indeed, for many areas and time periods, they are the only surviving examples of painting. They are also the best surviving specimens of medieval painting, and the best preserved. They are among the most common items to survive from the Middle Ages many thousands survive. Illuminated manuscripts continued to be produced in the early 16th century but in much smaller numbers, mostly for the very wealthy. The introduction of printing rapidly led to the decline of illumination. Drawings in the margins (known as marginalia) would also allow scribes to add their own notes, diagrams, translations, and even comic flourishes. Very early printed books left spaces for red text, known as rubrics, miniature illustrations and illuminated initials, all of which would have been added later by hand. Paper manuscripts appeared during the Late Middle Ages. Books ranged in size from ones smaller than a modern paperback, such as the pocket gospel, to very large ones such as choirbooks for choirs to sing from, and "Atlantic" bibles, requiring more than one person to lift them. A very few illuminated fragments also survive on papyrus. These pages were then bound into books, called codices (singular: codex). Most medieval manuscripts, illuminated or not, were written on parchment or vellum. While Islamic manuscripts can also be called illuminated and use essentially the same techniques, comparable Far Eastern and Mesoamerican works are described as painted. The majority of extant manuscripts are from the Middle Ages, although many survive from the Renaissance. Examples include the Vergilius Romanus, Vergilius Vaticanus, and the Rossano Gospels. The earliest surviving illuminated manuscripts are a small number from late antiquity, and date from between 400 and 600. Often used in the Roman Catholic Church for prayers, liturgical services and psalms, the practice continued into secular texts from the 13th century onward and typically include proclamations, enrolled bills, laws, charters, inventories and deeds. We describe how our idea can be used with existing image formats by embedding the estimated distribution in the RAW image to enable users to generate visually plausible white-balance images.Various examples of pages from illuminated manuscriptsĪn illuminated manuscript is a formally prepared document where the text is decorated with flourishes such as borders and miniature illustrations. Using this new ground truth data, we describe how to train a lightweight neural network method to predict the scene's illumination distribution. As part of this effort, we extend the Cube++ illumination estimation dataset to provide ground truth illumination distributions per image. Motivated by this observation, we revisit AWB to predict a distribution of plausible illuminations for use in white balance. We performed a user study that revealed that non-dominant illuminations often produce visually pleasing white-balanced images and, in some cases, are even preferred over the dominant illumination. However, in natural scenes, there are often many light sources present. AWB methods estimate an image's dominant illumination and use it as the target "white point" for correction. A camera's auto-white-balance (AWB) module operates under the assumption that there is a single dominant illumination in a captured scene.
