To better understand and preserve works of art, knowledge is needed about the pigments used to create the artwork. Various noninvasive techniques have been used previously to create pigment maps, such as combining X-ray fluorescence and hyperspectral

Deep Neural Networks (DNN) are now widely used in computer vision, due to their recent success in large-scale image classification. Despite the impressive performance of DNN in supervised optical character recognition (OCR) for handwritten documents,

A world map painted by Henricus Martellus c. 1491 is widely acknowledged to be of great importance in the history of cartography, but has been little studied since it came to the attention of scholars in 1959 because the pigments used to write the de

A few years ago, a young man to whom I had just been introduced told me that I had saved his life. I hardly knew who he was. "More properly, GPS saved my life," he continued, "and since you had so much to do with GPS, in a very real sense you saved m

Simulations of flatbed scanners can shorten the development cycle of new designs, estimate image quality, and lower manufacturing costs. In this paper, we present a flatbed scanner simulation a strobe RGB scanning method that investigates the effect

Error-diffused quantization has been applied to the generation of cell-oriented computer-generated Fourier transform holograms, resulting in reduced reconstruction errors. Improvements are demonstrated when applied to the algorithms of Lohmann, Lee a

This article describes the introduction of a specialized error diffusion algorithm to the quantization in cell-oriented computer generated holograms. This error diffusion quantization allows the adaptation of the calculation of the CGH to application
