Non-uniform illumination, cause problems in various areas of photography, such as mosaicing of panoramas, face recognition and microscopy. The remedying procedure is often called illumination or shading correction/normalisation. The paper propose a method that can be used both for minimising the change in intensity over the image, but also for increasing the contrast in low … Continue reading Illumination Correction – how to preserve medium sized objects

This paper propose an efficient way of visualising handwritten script signs based on their similarity. The image below to the left shows how the number one from the MNIST dataset has been clustered and visualised as small islands.  The image to the right shows a heat map of each island and one can clearly see … Continue reading Creating an Atlas over Handwritten Script Signs

  Libraries and cultural organisations have a rich amount of digitised historical handwritten material. A vast majority of this material has not yet been transcribed. The task of making these historical collections available for public access is challenging, especially in performing a simple text search across the collection. Machine learning based methods for handwritten text … Continue reading Making Large Collections of Handwritten Material Easily Accessible and Searchable
