Abstract: Framing a video effectively and efficiently in video conferencing, video recording, and live streaming can be a challenge. The framing decision preferably captures users and their actions without degrading the user experience. To address this challenge, a framing pipeline can be implemented to include a plurality of detectors, a multi-detector fusion, and a motion planner. Multi-detector fusion can merge detections produced by different detectors at different rates. Motion planner can change the framing decision based on a merged region of interest and a target region of interest produced by multi-detector fusion. The framing pipeline includes one or more features that can achieve a robust, temporally stable, and visually pleasing framed video frames that smoothly tracks users over time without causing unpleasant artifacts in the video conferencing experience.

Abstract: Systems, apparatus, articles of manufacture, and methods are disclosed to implement personalized skin tone adaptation for images and video. An example apparatus disclosed herein obtains an initial skin tone group distribution for an identified user depicted in an input image. The example apparatus also determines, based on the input image, a plurality of skin tone measurements associated respectfully with a plurality of skin tone groups corresponding to the initial skin tone group distribution. The example apparatus further outputs a revised skin tone group distribution based on the skin tone measurements, the initial skin tone group distribution, and a transition model.

Abstract: Systems, apparatus, articles of manufacture, and methods are disclosed for high quality and low power dynamic region of interest (ROI) cropping. An example apparatus disclosed herein provides a first image to image signal processor (ISP) circuitry, the ISP circuitry to implement an image processing pipeline to process the first image. The example apparatus also downscales the first image to generate a second image having lower resolution than the first image and identifies a region of interest (ROI) in the second image. The example apparatus further provides coordinates of the ROI to the ISP circuitry, the ISP circuitry to crop the first image based on the coordinates and to output a third image based on the cropped first image.

Abstract: Systems and methods for improving a temporal noise reducer (TNR) architecture that improves TNR performance and IQ. Temporal noise reduction is a core feature of a video processing pipeline, where TNR can be used to decrease noise in video streams. TNRs generally includes two main steps: motion analysis and blending. Motion analysis includes identifying moving elements, and can include generating a motion map indicating regions of the input image that are static versus regions with movement. Blending includes blending the current input image frame with the previous temporally-denoised frame. An architecture is provided that separates the motion analysis from the blending step. In particular, the architecture includes a motion analysis block that operates on the raw image at the start of the pipeline, while the blending operation is completed on the processed image at the end of the image processing pipeline.
