3,832 annotated images of scanned Hollywood pressbooks for object detection Model

From the 1910s through the 1980s, Hollywood studios promoted their movies through the creation and dissemination of pressbooks—bound pamphlets containing publicity materials, advertising layouts, accessories for sale, and other promotional tactics. These promotional booklets were sent to exhibitors and press outlets, making them vital nodes within the wider networks of film circulation and culture. This study investigates the reach of these publications by running similarity analyses between Hollywood pressbooks and Chronicling America, the Library of Congress’ expansive collection of local newspapers. High-throughput computing infrastructure and sophisticated machine vision workflows enable us to ask questions about Hollywood pressbooks, including who used them, how, and whether the publicity text, promotional photos, and ads from the pressbooks permeated American newspapers and magazines as the studios had intended.

## Description of the data and file structure

The dataset includes 25595 images. 3,832 images were manually reviewed and annotated by FitzWhittemore, Proctor, and Riley.

The following pre-processing was applied to each image:

* Auto-orientation of pixel data (with EXIF-orientation stripping)
* Auto-contrast via adaptive equalization

The following augmentation was applied to create 7 versions of each source image:

* 50% probability of horizontal flip
* Equal probability of one of the following 90-degree rotations: none, clockwise, counter-clockwise
* Random rotation of between -10 and +10 degrees
* Random shear of between -10° to +10° horizontally and -10° to +10° vertically
* Random brigthness adjustment of between -15 and +15 percent
* Random exposure adjustment of between -10 and +10 percent
* Salt and pepper noise was applied to 0....,
