Abstract: Devices and methods for selecting and stitching image frames are provided. A method includes obtaining a plurality of image frames. The method also includes identifying one or more regions of interest within one or more image frames in the plurality of image frames. The method further includes selecting, based on a respective quality measure associated with each image frame of the plurality of image frames, a set of base frames, where each identified region of interest of the one or more identified regions of interest is fully contained within at least one base frame in the selected set of base frames. The method additionally includes stitching together the selected set of base frames to create a composite image.

Abstract: Techniques and apparatuses are described that implement a camera manager system capable of generating frame suggestions from a set of frames. The camera manager system (120) utilizes at least one of a face diversity scorer (406) and an aesthetic diversity scorer (408), in conjunction with a time diversity scorer (404), to select and suggest diverse frames from a set of frames (304). In this way, the camera manager system (120) enables a computing device (102) to provide a user (10) of the computing device with a better selection of suggested frames. Through the better selection of suggested frames, the computing device (102) can improve the quality of the user’s experience in using the computing device and/or a camera application of the computing device. The better selection of suggested frames further decreases wasted resources (e.g, similar image storage, processor usage to process the capture of additional frames, battery usage associated with capturing additional frames, and the like).
