Event Details

Attending IS&T this year at the National Archives in Washington D.C.? Join Doug Peterson, Product Manager at DTDCH, on Tuesday April 19th for our Short Course on Automatic Cropping and Deskewing.

Instructor: Doug Peterson, Cultural Heritage

Manually cropping images is labor intensive and tedious. Properly implemented, automatic cropping and deskewing can drastically reduce the time spent on this undesirable but essential task. But automatic cropping tools are not panaceas with human ­like intelligence; they are just tools with strengths and weaknesses, abilities, and limitations.

This class covers some of the theory behind automatic cropping and discusses several factors that determine the efficacy of an automatic cropping solution. We’ll explore a variety of workflows and tools that ameliorate inherent limitations and challenges of automatic cropping and deskewing. For instance, we’ll discuss how to use a “Temporary Contrast Prepass” to ensure accurate automatic cropping when there is limited tonal contrast between the subject and the background (e.g. white paper on a white background). As a logical extension, we discuss various ways to batch manipulate the crop of a set of images. How to produce derivatives with and without an Object Level Target or page split books is also addressed.

This course enables the attendee to:

  • Distinguish situations where automatic cropping and deskewing can be highly effective from situations where automatic cropping and deskewing is not currently possible
  • Understand how an automatic cropping and deskewing algorithm detects the Region of Interest
  • Modify capture workflows to facilitate effective automatic cropping and deskewing
  • Identify workarounds for situations that would typically challenge automatic cropping and deskewing tools
  • Leverage automatic cropping and deskewing to greatly increase total productivity

Intended Audience
This course is geared toward those responsible for digitization. It is equally helpful for those “in the trenches” of digitization and managers thereof. Basic experience with digitization workflows is important. Basic experience with Capture One Cultural Heritage 8 is helpful, but not essential. Previous experience with automatic cropping and deskewing workflows is not required; the class begins with the basics before continuing to advanced topics.

Doug Peterson is head product manager at the Digital Transitions Division of Cultural Heritage. He has helped many clients implement and refine automatic cropping and batch cropping workflows and worked closely with Phase One on their implementation of AutoCrop in Capture One Cultural Heritage 8.
