Abstract: Techniques and systems are provided for processing one or more low light images. For example, a short exposure image associated with one or more shutter speeds can be obtained. A long exposure image is also obtained, which is captured using a slower shutter speed than the one or more shutter speeds associated with the short exposure image. An output image can be generated by mapping color information from the long exposure image to the short exposure image.

Abstract: Techniques and systems are provided for segmenting one or more frames. For example, incremental optical flow maps can be determined between adjacent frames of a plurality of frames. Using the incremental optical flow maps, a cumulative optical flow map can be determined between a first frame of the plurality of frames and a last frame of the plurality of frames. A segmentation mask can be determined using the first frame of the plurality of frames. Foreground pixels of the segmentation mask for the last frame of the plurality of frames can then be adjusted relative to corresponding foreground pixels for the first frame. The foreground pixels can be adjusted using the cumulative optical flow map between the first frame and the last frame of the plurality of frames.

Abstract: Systems and methods are provided for trimming content for projection within the bounds of a projection target. The systems and methods trim the content for projection based on one or more characteristics of the projection target, including a shape, outline, and distance to the projection target. Moreover, the systems and methods designate void areas where no content will be projected based on the one or more characteristics, and the void areas will be generated or otherwise projected along with the content so that the content is projected onto the projection target and the void areas are projected outside of the projection target such that the projected content does not significantly spill onto surfaces or objects outside of the projection target.

Abstract: Systems, methods, and computer-readable media are provided for transferring color information from a no-flash image of a scene to a flash image of the scene using a localized tonal mapping algorithm. In some aspects, an example method can include obtaining a no-flash image and a flash image, mapping color information from the no-flash image to the flash image, and generating an output image including the flash image modified based on the mapping to include at least a portion of the color information from the no-flash image.

Abstract: Techniques and systems are described herein for determining dynamic lighting for objects in images. Using such techniques and systems, a lighting condition of one or more captured images can be adjusted. Techniques and systems are also described herein for determining depth values for one or more objects in an image. In some cases, the depth values (and the lighting values) can be determined using only a single camera and a single image, in which case one or more depth sensors are not needed to produce the depth values.

Abstract: Techniques are described for combining two or more images that are taken with varying brightness degrees to generate a composite image. In one embodiment, at least two weight masks are generated based on one or more characteristics of the two or more images. A first image A first weight mask is used to combine color channels of one or more pixels of the two or more images and a second weight mask is used to combine intensity channels of the one or more pixels of the two or more images.
