Image Processing Services

If you’ve already scanned your books or microfilm to digital files, we can make them better. Of course, Creekside Digital can also apply these processing options to scans we create for you from books or microfilm we digitize for you.

Black Border Removal / Deskew

Black Border Removal / Deskew -- Before & After

Often, raw images coming off of a scanner will be crooked, or “skewed,” and have black borders (“overscan”) showing around the edges of the original document scan. This wastes disk space by making the document files larger than they need to be, and reduces Optical Character Recognition accuracy. Creekside Digital can remove the black borders from around your scans and straighten the document at the same time, which results in smaller file sizes that will be processed more accurately by OCR. And yes, we can process grayscale and colors images, with absolutely no loss of quality! Our server-based software can process thousands of images per hour.

Geometric Curve Correction

When a bound book is digitized, the resulting scanned pages will have a certain degree of curvature to them where the pages meet in the book’s gutter – even when taking steps to minimize the effect such as using a V-shaped book cradle or glass plate to flatten the pages. To remove this distortion and maximize the accuracy of subsequent OCR processes, Creekside Digital uses cutting-edge algorithms to geometrically restore the original shape of the pages and the content they contain. We can implement this processing on scans of bound books as well as scans of microfilm containing images of bound books.

Geometric Curve Correction -- Before & After

Background Removal and Lighting Correction

Often, scans of bound works will have dark shadows present in the gutter area, due to excessive curvature or where lighting from the sides didn’t properly illuminate the entire page surface. Creekside Digital can identify and remove or minimize these shadows as well as other lighting problems such as hotspotting and glare / reflections from poorly placed illumination.

Bitonal Conversion / Downscaling / Format Shifting and Derivatives

If you don’t need all of your documents to be color or grayscale, or stored at the high resolution at which they were originally scanned, Creekside Digital can help! Our batch conversion services can process thousands of images an hour to quickly reduce color depth, decrease resolution, and shift file formats – resulting in smaller files which open faster and take up less disk space to store.

We can also create any required derivatives from your archival Digital Master files: for example, JPEG2000 lossy / lossless, downscaled searchable PDF, and XML structural metadata from your uncompressed TIFF master. Contact us for details.

PDF Compression

Using best-in-class technology from LuraTech, Creekside Digital can process your existing documents to reduce the size of your PDF files by 85% or more compared to standard PDF files. This processing results in smaller PDF files which take up less disk space, open faster, and work better on older PCs while retaining the details captured by grayscale images such as fine handwriting, rubber stamps, embossed seals, and photographs.

We're super-pleased to be part of this important project! This work is being performed to the #FADGI 4-Star specifications -- the highest level of quality possible under the Federal guidelines for the #digitization of cultural heritage materials. ... See MoreSee Less

The pilot project with the Smithsonian National Postal Museum continues and we're blowing away our projected results! The NPM object handling team has really come together, the Smithsonian team behind the scenes supporting our virtual workflow has helped us work out the minor kinks, and our vendor Creekside Digital has graciously extended our targeted number of objects, so we're up to 1,998 objects through today already--way to go team!

Creekside Digital shared Veterans Curation Program's post. ... See MoreSee Less

The Alexandria VCP had the opportunity to visit the Smithsonian National Postal Museum this week to see a Rapid Capture Digitization Project with the Smithsonian Digitization Program Office. The project, which is a collaboration of efforts by the Smithsonian’s Digitization Program Office, the National Postal Museum, and Creekside Digital, will include the digitization of 1,000 sheets of postal stamps in less than a week. To view the project in person, please visit the National Postal Museum this week, September 29th through October 2nd, between 10:00am and 4:00pm for an Open House. Unable to attend the Open House? Check the project out at the Smithsonian’s Digitization Program Office’s website at and the National Postal Museum’s blog at The Alexandria staff was also honored to have a tour of the world’s largest stamp gallery by the Museum Director, Allen Kane! Allen walked the staff through the gallery, telling some of the stories behind the stamps. The staff viewed a letter that was on the Hindenburg when it caught fire, Amelia Earhart’s flight suit, and the world’s most famous stamp, the British Guiana 1c Magenta, which had been owned by John Eleuthère du Pont. Staff also tested some of the interactive displays in the exhibit and created a stamp with self-portraits! The Alexandria VCP would like to thank Allen Kane for taking time to provide such a wonderful visit!
