Image editing

We carry out mass editing of digital images for archives, universities, libraries, museums and others. Typical applications include; colour enhancement/restoration, addition of Copyright statement, watermarking, deskew, despeckle, rotate, resize, add/remove visible metadata and renaming of files:

Carina Nebula, Hubble Space Telescope, July 2009. The poor-quality nth-generation derivative image on the left has been colour-corrected via the original NASA data, rotated, resized, despeckled and deskewed to emulate NASA’s own corresponding published imagery. It was then renamed according to the batch metadata, watermarked top right, and Copyright-, date- and time-stamped bottom left. Click on the images to see the full-sized versions. These bulk editing processes can be applied to any image collection regardless of size.

Deduplication

We offer two deduplication techniques; removal of exact duplicates (“weeding”) and identification of similar images (“lookalikes”):

Weeding

We locate files which are identical in computing terms and therefore to the human eye but which have different names or locations. The collection can then be weeded to free up storage space.

Lookalikes

We are able to identify visually similar images according to a given resemblance threshold; these would get through the above weeding process undetected. This powerful technique will for example find lookalikes which have been saved in different file formats, at different sizes, or at different resolutions.

Image enhancement

Our expert techniques get the most out of your images, allowing digital artwork restoration, crime scene photography analysis, and other image enhancement applications.
