Abstract:
Systems and methods for providing panoramic image and/or video content using multi-resolution stitching. Panoramic content may include stitched spherical (360-degree) images and/or VR video. In some implementations, multi-resolution stitching functionality may be embodied in a spherical image capture device that may include two lenses configured to capture pairs of hemispherical images. The capture device may obtain images (e.g., representing left and right hemispheres) that may be characterized by 180-degree (or greater) field of view. Source images may be combined using multi-resolution stitching methodology. Source images may be transformed to obtain multiple image components characterized by two or more image resolutions. The stitched image may be encoded using selective encoding methodology including: partitioning source images into a low resolution/frequency and a high resolution/frequency components; stitching low resolution/frequency components using coarse stitching operation, stitching high resolution/high frequency components using a refined stitch operation; combining stitched LF components and stitched HF components.
