Special Issue Information

Dear Colleagues,

Deep learning algorithms have significantly transformed the landscape of recognition technologies. In contemporary settings, these advanced algorithms excel, often outperforming humans in tasks such as image classification. This process is not only limited to recognizing flat images but extends to more complex operations like pixel-wise classification and object detection, where their performance remains impressive.

However, the scenario shifts when dealing with three-dimensional data. Tasks involving the recognition of objects in range images, depth maps, point clouds, and stereo images introduce unique challenges. Despite substantial progress and dedicated efforts in the field, these challenges are yet to be fully mastered. The complexities of three-dimensional data processing demand innovative approaches and refined algorithms to achieve results comparable to those obtained with two-dimensional data.

In response to these ongoing developments, we are proud to announce a Special Issue entitled "Current Advances in 3D Scene Classification and Object Recognition". This edition is dedicated to exploring groundbreaking and rigorous research that integrates various learning paradigms with three-dimensional data across multiple contexts. This Special Issue aims to highlight novel methodologies and significant advancements in several areas, including, but not limited to, enhanced algorithms for depth perception, improved techniques for processing point clouds, and innovative applications in stereo imaging. This issue will serve as a platform for scholars and practitioners to disseminate their findings and contribute to the evolving field of 3D data analysis.

Specifically, this Special Issue will cover the following topics, among others:

  • Deep Learning and machine learning with point clouds;
  • Deep Learning and machine learning with depth maps;
  • Deep Learning and machine learning with stereo vision;
  • Three-dimensional keypoint detectors and descriptors;
  • Novel representations of 3D data;
  • Three-dimensional data summarization and compression;
  • Object detection taking as input any 3D data;
  • Point-wise classification taking as input any 3D data.

Accurate and fast 3D mapping of crime scenes is crucial in law enforcement, and first responders often need to document scenes in detail under challenging conditions and within a limited time. Traditional methods often fail to capture the details required to understand these scenes comprehensively. This study investigates the effectiveness of recent mobile phone-based mapping technologies equipped with a LiDAR (Light Detection and Ranging) sensor. The performance of LiDAR and pure photogrammetry is evaluated under different illumination (day and night) and scanning conditions (slow and fast scanning) in a mock-up crime scene. The results reveal that the mapping using an iPhone LIDAR in daylight conditions with 5 min of fast scanning shows the best results, yielding 0.1084 m of error. Also, the cloud-to-cloud distance showed that 90% of the point clouds exhibited under 0.1224 m of error, demonstrating the utility of these tools for rapid and portable scanning in crime scenes.

This paper presents a comparative study of the Vertex Block Descent (VBD) and Position-Based Dynamics (PBD) algorithms, focusing on their performance in physical simulation tasks. Unity, a versatile physics engine, served as the simulation platform for the experiments. Among various types of physical simulations of deformable objects, fluids, and cloth dynamics, cloth simulations were chosen for implementation with both algorithms. The experimental setup ensured identical parameters, including time steps and movement behavior, for both algorithms across scenarios involving hanging, object-to-object collisions, and self-collisions. The results indicate that while the performance difference in frames per second (fps) between the two algorithms is negligible for simulations with a small number of nodes, the VBD algorithm consistently outperforms the PBD algorithm as the node count increases. Furthermore, this study provides practical guidelines for maintaining real-time performance, detailing the maximum node count each algorithm can support, while sustaining a minimum threshold of 30 fps, which is necessary for real-time applications. The comparison was conducted using CPU-based computation to establish a baseline for future studies in GPU-accelerated environments, where parallel processing is expected to further highlight the performance advantages of VBD. Future work will extend this research by evaluating additional physical simulation models, including the Mass-Spring System and Extended Position-Based Dynamics (XPBD), and developing optimizations to enhance the efficiency and scalability of these algorithms.

A variety of methods for 3D object recognition and registration based on a deep learning pipeline have recently emerged. Nonetheless, these methods require large amounts of data that are not easy to obtain, sometimes rendering them virtually useless in real-life scenarios due to a lack of generalization capabilities. To counter this, we propose a novel local descriptor that takes advantage of the fractal dimension. For each 3D point, we create a descriptor by computing the fractal dimension of the neighbors at different radii. Our redmethod has many benefits, such as being agnostic to the sensor of choice and noise, up to a level, and having few parameters to tinker with. Furthermore, it requires no training and does not rely on semantic information. We test our descriptor using well-known datasets and it largely outperforms Fast Point Feature Histogram, which is the state-of-the-art descriptor for 3D data. We also apply our descriptor to a registration pipeline and achieve accurate three-dimensional representations of the scenes, which are captured with a commercial sensor. Full article
