Abstract: Methods, systems, and devices for motion analysis are described. Generally, the described techniques provide for computationally efficient and accurate motion analysis. A device may identify frames of a video frame sequence having a defined resolution. The device may downscale the frames to generate a plurality of downsampled images each having a resolution lower than the defined resolution. The device may generate a respective histogram vector for each pixel of each downsampled image and each pixel of the original frames. The device may determine a motion vector candidate based at least in part on the histogram vectors. The device may apply a filter to the motion vector candidates to determine a final motion vector and output an indication of motion between the frames of the video frame sequence based at least in part on the final motion vector for each pixel of the second frame.

Abstract: A method includes receiving a user input (e.g., a one-touch user input), performing segmentation to generate multiple candidate regions of interest (ROIs) in response to the user input, and performing ROI fusion to generate a final ROI (e.g., for a computer vision application). In some cases, the segmentation may include motion-based segmentation, color-based segmentation, or a combination thereof. Further, in some cases, the ROI fusion may include intraframe (or spatial) ROI fusion, temporal ROI fusion, or a combination thereof.
