US 2026/0065544 A1 · VIDEO CONTENT TO SLIDE GENERATION

Abstract

Presentations are often broadcast or video recorded without handouts, such as the slides presented by a presenter of the presentation. Without handouts it is difficult and resource intensive to identify a particular slide of interest. Systems and methods are provided to automatically convert frames of a presentation video (e.g., a file or broadcast) to images in a document (e.g., Word™, PDF, etc.). Frames of the presentation are included in the document unless excluded. The frames are excluded when determined to be duplicative of a previous frame. Frames are duplicative if they are determined to be identical or nearly identical when hashed via an image hashing function. A non-identical frame is further determined to be duplicative when not identical to a previous frame but the differences are limited to only irrelevant visual content (e.g., the presenter gesturing).

Claims20

Dependent claims

A method for compressing a video presentation, comprising:

capturing a first still image from a first frame of the video presentation;
writing the first still image to a document;
capturing a second still image from a second frame of the video presentation;
comparing the first still image to the second still image to determine whether the difference is greater than a threshold;
and
when the difference is greater than the threshold, writing the second still image to the document and when the difference is not greater than the threshold, omitting writing the second still image to the document.

3 more elements

A system for compressing a video presentation, comprising:

at processor coupled to a computer memory comprising computer-readable instructions to cause the processor to:
capture a first still image from a first frame of the video presentation;
write the first still image to a document;
capture a second still image from a second frame of the video presentation;
compare the first still image to the second still image to determine whether the difference is greater than a threshold;
when the difference is greater than the threshold, write the second still image to the document and when the difference is not greater than the threshold, omit writing the second still image to the document;
and
cause a data storage component to store the document.
