Abstract
Provided is a method for the automatic determination of a region of interest in an image, comprising the steps of: segmenting the image into a plurality of smaller regions, each region extending over a plurality of pixels; performing an analysis on each of said regions to characterize an aspect of the region relating to its level of importance in communicating information to a viewer; grouping adjacent regions having similar aspect characteristics; and identifying at least one group as a region of interest. Also provided is a method employing the steps above for use in an automated document composition process, where overlaid content is not placed over regions of interest that are identified.
Claims18
A method for the automatic determination of a region of interest in an image, comprising:
- segmenting the image into a plurality of smaller regions, each region extending over a plurality of pixels;
- performing an analysis on each of said regions to characterize an aspect of the region relating to its level of importance in communicating information to a viewer, wherein said step of performing an analysis, includes determining a contrast value as an aspect characteristic for each region and averaging the contrast values across multiple regions;
- grouping adjacent regions having similar aspect characteristics;
- and
- identifying at least one group as a region of potential overlay.
An automated document composition process, comprising:
- receiving a document including at least one image therein;
- specifying content to be overlaid on at least a portion of the image;
- identifying at least one low interest region of the image upon which the content may be overlaid, including segmenting the image into a plurality of smaller regions, each region extending over a plurality of pixels, performing an analysis on each of said regions to characterize an aspect of the region relating to its level of importance in communicating information to a viewer, grouping adjacent regions having similar aspect characteristics, and identifying at least one group as a region of interest, wherein performing an analysis, comprises
- determining a contrast value as an aspect characteristic for each region;
- and
- averaging the contrast values across multiple regions;
- and automatically inserting at least a portion of the content into at least the one region.
