Auto Cropping for Advertisement from a 360 Image

Abstract

In recent years, computational photography technology can achieve expressions by computational calculation. As part of this technology, it is now possible to synthesize multiple camera images into 360-degree images. Ricoh has developed the world's first consumer 360-degree camera, THETA, which generates 360-degree images by combining two low-parallax fisheye lenses through the stitching. 360-degree images are widely used as advertisements of real estate. However, taking 360-degree images is time-consuming work for real estate agents because they also take conventional photos. Therefore, this paper will explain auto-cropping which reduces the amount of time for taking conventional photos by cropping conventional images from a 360-degree image.
