Special Issue Information

High dynamic range (HDR) imaging is a well-established technology that enables the acquisition, storage, manipulation, delivery, and evaluation of a higher dynamic range than the one available in traditional 8-bit per color channel technology (standard dynamic range (SDR) technology). This has brought a number of advantages, such as more realistic color reproduction, more details in bright and dark areas, better contrast, improved colors, etc. This has revolutionized the way we are now experiencing entertainment, as well as the way we are using images and videos in the image processing and computer vision fields. HDR imaging has finally moved from academia to the market.

We are experiencing a large use of HDR technology in the entertainment sector, and are also starting to see its use in industrial applications. On the other hand, we are assisting in a paradigm change in the image-processing area, where traditional techniques are surpassed by more flexible deep-learning-based approaches. In the last few years, we are also observing this specific trend in the HDR imaging field. This has brought a number of challenges that need to be addressed in order to make deep-learning-based HDR approaches more robust and resilient to unseen data and/or data which is too noisy.

Topics included but not limited to

Deep-learning-based techniques for images/videos for:

  • High dynamic range (i.e., camera, image and vision, sensors);
  • Single/multi-exposure HDR content acquisition;
  • Image fusion for HDR content;
  • HDR formats and standardization;
  • HDR objective metrics;
  • HDR de-ghosting artifacts removal;
  • Tone mapping/inverse tone mapping;
  • Color correction for HDR content;
  • Gamut adjustment for HDR content;
  • Real-time HDR applications;
  • Mixed reality for HDR;
  • Image-based lighting.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sensors is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs).

Inverse Tone Mapping (ITM) methods attempt to reconstruct High Dynamic Range (HDR) information from Low Dynamic Range (LDR) image content. The dynamic range of well-exposed areas must be expanded and any missing information due to over/under-exposure must be recovered (hallucinated). The majority of methods focus on the former and are relatively successful, while most attempts on the latter are not of sufficient quality, even ones based on Convolutional Neural Networks (CNNs). A major factor for the reduced inpainting quality in some works is the choice of loss function. Work based on Generative Adversarial Networks (GANs) shows promising results for image synthesis and LDR inpainting, suggesting that GAN losses can improve inverse tone mapping results. This work presents a GAN-based method that hallucinates missing information from badly exposed areas in LDR images and compares its efficacy with alternative variations. The proposed method is quantitatively competitive with state-of-the-art inverse tone mapping methods, providing good dynamic range expansion for well-exposed areas and plausible hallucinations for saturated and under-exposed areas. A density-based normalisation method, targeted for HDR content, is also proposed, as well as an HDR data augmentation method targeted for HDR hallucination. Full article
