Table 1: Status of JPEG Systems ISO projects. application providing the service for virtual reality (VR) or 360-degree image services. To discard this unnecessary conversion of metadata formats, the JPEG working group (WG) developed the JPEG 360 international standard to guarantee the use of standardized metadata from the image-acquisition stage. In this context, as previously pointed out, the conversion of numerous images existing in the JPEG-1-dominant digital imaging environment to JPEG 360 is regarded as an essential task in continuing existing consumers' applications and services. The 360-degree images or panorama-generation systems and algorithms proposed in the literature mostly did not care about the metadata. Without proper metadata, the real purpose of such images cannot be achieved. To the best of the authors' knowledge, such an approach of implementing the emerging international standard has not been attempted before. Our work enables the transformation of a large amount of legacy 360-degree images into the standardized format, which provides a market to use the format in a standard way, which was a goal of developing the JPEG 360 standard. In this work, we also propose a low-cost panorama-acquisition system from a single pan-tilt-zoom (PTZ) camera. Our PTZ panorama application is the practical use case of our converter. The panorama will be compatible with the JPEG 360 standard and help consumers in situations such as capturing a wide field of view image of a conference or meeting. These days, because of COVID-19, virtual and online meetings/conferences have replaced face-to-face meetings [15; 16; 17]. We believe that if our PTZ panorama, with proper metadata values in the standard format, are shared with a remote attendee of a conference/meeting, he/she can see the realistic and immersive environment by viewing our PTZ panorama virtually. This paper presents the implementation of JPEG 360 to convert conventional 360-degree images to standard JPEG 360 images and the acquisition of the standard JPEG 360 panorama using a single PTZ camera. Section 2 presents a brief overview of related work. In this section, we introduce the JPEG-1 image coding standard and the JPEG-1 file structure. We also introduce standard formats used for embedding application-specific metadata to a JPEG-1 file.
