Abstract

Provided are a method, system, and article of manufacture for generating a video output by combining a first video input and a second video input. A first input image is accessed from the first video input and a second input image is accessed from the second video input, wherein the second input image includes a selected element recorded in front of a monochromatic background. A first region and a second region are generated from the first input image. An output image that includes the first region and the second region with a gap separating the first region from the second region is generated. The selected element is placed at least over the gap in the output image, wherein predetermined areas of the first region and the second region remain visible in the output image. The output image is included in the video output.

in response to the generating of the output image, placing the selected element at least over the gap in the output image, wherein predetermined areas of the first region and the second region remain visible in the output image; and

in response to the placing of the selected image at least over the gap, including the output image in the video output, wherein the selected element is an area of that includes text, wherein the generating of the first region and the second region and the placing of the area that includes the text causes that area that includes the text to be mapped around a moving presenter, wherein the text always remain readable to a viewer.

2. The method of claim 1, wherein the first input image comprises a presentation material, wherein the second input image comprises a presenter standing in front of the monochromatic background, wherein the presenter is the selected element included in the second input image, wherein in the output image the presenter does not obscure the predetermined areas included in the presentation material, and wherein the first video input and the second video input are received by a computational device that generates the video output in real time.

3. The method of claim 1, wherein the first region includes a first set of text and the second region includes a second set of text, and wherein the predetermined areas that remain visible in the output image include the first set of text and the second set of text.

4. The method of claim 1, wherein the first input image is split into the first region and the second region based on physical features included in the first input image.

5. The method of claim 1, wherein the compressed version of the first region, the compressed version of the second region, and the gap fit the provided screen size, without loss of visually identifiable features.

6. A system for generating a video output by combining a first video input and a second video input, the system comprising:

memory; and

processor coupled to the memory, wherein the processor executes operations, the operations comprising;

accessing a first input image from the first video input and a second input image from the second video input, wherein the second input image includes a selected element recorded in front of a monochromatic background;

in response to the accessing, generating, via the processor, a first region and a second region from the first input image;

in response to the generating of the first region and the second region, generating an output image of a provided screen size that includes a compressed version of the first region and a compressed version the second region with a gap separating the first region from the second region;

in response to the generating of the output image, placing the selected element at least over the gap in the output image, wherein predetermined areas of the first region and the second region remain visible in the output image; and

in response to the placing of the selected image at least over the gap, including the output image in the video output, wherein the selected element is an area of that includes text, wherein the generating of the first region and the second region and the placing of the area that includes the text causes that area that includes the text to be mapped around a moving presenter, wherein the text always remain readable to a viewer.

7. The system of claim 6, wherein the first input image comprises a presentation material, wherein the second input image comprises a presenter standing in front of the monochromatic background, wherein the presenter is the selected element included in the second input image, wherein in the output image the presenter does not obscure the predetermined areas included in the presentation material, and wherein the first video input and the second video input are received by a computational device that generates the video output in real time.

8. The system of claim 6, wherein the first region includes a first set of text and the second region includes a second set of text, and wherein the predetermined areas that remain visible in the output image include the first set of text and the second set of text.

9. The system of claim 6, wherein the first input image is split into the first region and the second region based on physical features included in the first input image.

10. The system of claim 6, wherein the compressed version of the first region, the compressed version of the second region, and the gap fit the provided screen size, without loss of visually identifiable features.

11. A computer readable storage medium for generating a video output by combining a first video input and a second video input, wherein code stored in the computer readable storage medium when executed by a processor causes operations, the operations comprising:

accessing a first input image from the first video input and a second input image from the second video input, wherein the second input image includes a selected element recorded in front of a monochromatic background;

in response to the accessing, generating, via the processor, a first region and a second region from the first input image;

in response to the generating of the first region and the second region, generating an output image of a provided screen size that includes a compressed version of the first region and a compressed version the second region with a gap separating the first region from the second region;
