Image mosaicing for aerial photography

Aerial surveys are a common conservation technique. They will typically consist of a number of photographs taken from a plane, which are then stitched into a much larger image which contains a large area. These stitched images are then used to count animals, monitor populations, etc. At the moment, these techniques are based on classic […]

Removing noise from hand-written transcriptions

An OCR tool developed in the school can recognise hand-written transcriptions of Ancient Egyptian. One of the remaining obstacles is ‘hatching’, that is, diagonal lines drawn to indicate that the text on the original artefact was damaged. This interferes with the segmentation into individual signs. The purpose of the project is to experiment with image […]

Identifying features in salmon scales using Computer Vision

This is a computer vision project on automatically finding the focal point (or the growth centre) of concentric growth rings on images on salmon scales. See also related project involving image processing.     Salmon scales contain visible concentric rings which can be used to determine the age and growth history of individual fish, much like […]

Analysis of early printed editions

This project is in conjunction with Dr. Clive Sneddon from the St Andrews Institute of Mediaeval Studies. The task is to develop data formats and algorithms to analyse digitisations of early printed French bibles, obtained via OCR. Early French bibles pose a number of challenges for computer processing. For particular editions, there is the problem […]

Annotation of textual artefacts and image distortion

The image of a textual artefact (consider the famous Rosetta stone) can be annotated with relevant (x,y) coordinates, e.g. where a certain word is found. Suppose now someone provides a better photo of the same object, but from a slightly different angle. Can we (semi-)automatically translate the (x,y) coordinates from the old photo to the […]
