Abstract
Techniques and systems are described for automatic content-aware collages. Collage templates are generated based on generated set of initial points. Salient regions are determined within digital images, and the salient regions are matched with cells of a collage template. Chrominance of digital images may be mediated to provide a cohesive color scheme among the digital images, and geometric parameters of digital images may be generated to optimize visible salient regions within cells of the template. A collage is generated incorporating the digital images in corresponding cells of the template.
Claims20
In a digital medium environment to generate a collage from a plurality of digital images, a method implemented by a computing device, the method comprising:
- generating, by the computing device and responsive to receiving a user input, a template including a plurality of cells based on a set of initial points;
- determining, by the computing device and for each respective one of the plurality of digital images, a salient region based on a visual saliency of respective pixels in the respective digital image;
- matching, by the computing device, respective salient regions with respective cells based on a comparison of the salient region with the cell;
- generating, by the computing device, the collage as including the plurality of digital images based on the template and the matching;
- and
- outputting, by the computing device, the collage.
In a digital medium environment to generate a collage from a plurality of digital images, a system comprising:
- a template generation system configured to generate a template including a plurality of cells based on a set of initial points and responsive to receiving a user input to initiate creation of the collage, each cell of the plurality of cells being a complex shape;
- an image saliency system configured to determine, for each respective one of the plurality of digital images, a salient region based on a visual saliency of respective pixels in the respective digital image;
- a shape matching system configured to match respective salient regions with respective cells based on a comparison of the salient region with the cell;
- a media content editing application configured to generate the collage as including the plurality of digital images based on the template and the matched regions.
In a digital medium environment to generate a collage from a plurality of digital images, a system comprising:
- means for generating, responsive to receiving a user input to initiate creation of the collage, a template including a plurality of cells based on a set of initial points;
- means for determining, for each respective one of the plurality of digital images, a describing salient region based on a visual saliency of respective pixels in the respective digital image;
- means for matching respective salient regions with respective cells based on a comparison of moment features of the salient region with moment features of the cell, a moment feature describing characteristics of a respective group of pixels;
- means for generating the collage as including the plurality of digital images based on the template and the matching.
