**Preface to "Digital Signal, Image and Video Processing for Emerging Multimedia Technology"**

Recent developments in image/video-based deep learning technology have enabled new services in the field of multimedia and recognition technology. The technologies underlying the development of emerging services are based on essential signal and image processing algorithms. In addition, the recent realistic media services, mixed reality, augmented reality and virtual reality media services also require very high definition media creation, personalization and transmission technologies, and this demand continues to grow. To accommodate these needs, international standardization organizations and industries are studying various digital signal and image processing technologies to provide a variety of new or future media services. In this issue, we present a collection of quality papers concerning advanced signal/image processing and video data processing, including deep learning approaches. This book comprises 23 peer-reviewed articles covering a review of the development of deep-learning-based approaches and presenting original research on learning mechanisms and video signal processing. This book also covers topics including data security and protection and advanced digital signal/image processing. This volume will be a good collection for designers and engineers in both academia and industry that would like to develop an understanding of emerging technology in digital signal, image and video processing, and students will also find this book to be a useful reference.
