Investigations have been carried out on the distribution of AgBr-grains in unexposed photographic plates (type Q2, 11 f o r d Ltd.) used for ion detection in mass-spectrometers. Electron micrographs show that a large fraction of the grains protrude about halfway out of the gelatine matrix and that these grains are covered by a very thin gelatine layer on the side facing the ions. The mean proje...

The term provenance is traditionally applied to works of art, referring to documentation which relates to the ownership and public visibility of a particular work, but also includes documentation of production, restoration, thefts, expert opinions on condition and valuations, and any other records which help to assess its integrity. In the realm of criminal evidence, the term chain-of-evidence ...

A photographic dataset is collected for testing image processing algorithms.

The rapid growth of IT industry today has undoubtedly boosted the widespread use of computer images in both web pages and modern computer programs. Applications like online image search, automatic webpage summarization and web mining, rely heavily on image categorization. This project presents a system that categorizes non-photographic images 1 based on their textual and image features. The cor...

We propose a technique to modify colors in photographic images predicting the color appearance of objects in an image under different illuminations. Using the dichromatic surface reflectance model, we estimate the illumination spectrum and the spectrum of the diffuse surface reflectance via the color histogram and subspace analyses. With this estimated spectral information, and the spectrum of ...
