Special Issue Information

Dear Colleagues,

We are witnessing the wide diffusion of active depth sensors that represent an effective and affordable solution to capture 3D information even in low-light conditions. At the same time, computer vision and machine learning communities proposed new solutions to process depth data, individually or fused with other information such as RGB images. However, the generalization capabilities and performance of the deep learning models based on depth data, such as a depth map and its related data representations (e.g., normal images, voxels, and point clouds) have not yet been fully investigated. In this context, several challenging problems can be addressed, such as the reliable detection of people, the 3D analysis of humans in terms of body pose, and face and hand analysis, also oriented for the human–computer interaction and biometrics.

This Special Issue will publish innovative work that explores hardware and software solutions for exploiting depth information, investigating the use of ad hoc deep learning models and specific data pre-processing and normalization procedures. The particular topics of interest include, but are not limited to the following:

  • people (and face) detection;
  • human body pose estimation and refinement;
  • people tracking;
  • head pose estimation;
  • face recognition and verification;
  • face analysis;
  • action recognition;
  • gait analysis;
  • human–computer interaction;
  • hand detection;
  • hand pose estimation;
  • gesture recognition;
  • depth-based data representations

Manuscript Submission Information

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.

With the majority of research, in relation to 3D object reconstruction, focusing on single static synthetic object reconstruction, there is a need for a method capable of reconstructing morphing objects in dynamic scenes without external influence. However, such research requires a time-consuming creation of real world object ground truths. To solve this, we propose a novel three-staged deep adversarial neural network architecture capable of denoising and refining real-world depth sensor input for full human body posture reconstruction. The proposed network has achieved Earth Mover and Chamfer distances of 0.059 and 0.079 on synthetic datasets, respectively, which indicates on-par experimental results with other approaches, in addition to the ability of reconstructing from maskless real world depth frames. Additional visual inspection to the reconstructed pointclouds has shown that the suggested approach manages to deal with the majority of the real world depth sensor noise, with the exception of large deformities to the depth field.
