Ethical Dilemmas in the Sciences [From the Editor] IEEE Signal Proc. Mag. (IF 15.204) Pub Date : 2022-05-06 Christian Jutten
“Science without conscience is only ruin of the soul” said François Rabelais. This centuries-old quote still resonates, today maybe louder than ever. I began to write this editorial at the end of February when Russian tanks and soldiers invaded Ukraine and waves of bombers began dropping their bombs on Ukrainian cities, targeting civilian buildings, hospitals, and schools. This dramatic event was a

While I am writing this column, the Russia–Ukraine war is raging. As bombings, destruction, and human suffering flood the daily news, I deeply feel the pain of our Ukrainian colleagues, those who have friends and family in the affected areas, those who had to put their studies and careers on hold to fight for their survival. I also acknowledge the agony of those around the world who are watching the

Fire, Water, and Signal Processing: Researchers are turning to signal processing to help them address challenges posed by two of the planet’s fundamental forces [Special Reports] IEEE Signal Proc. Mag. (IF 15.204) Pub Date : 2022-05-06 John Edwards
Fire and water, two of nature’s basic forces, are each capable of sustaining or destroying life and property. Research projects in California and Hawaii are, respectively, helping displaced families cope with devasting wildfires, and investigating a way to increase water supply availability on isolated islands. Both projects are relying on signal processing to help them meet their goals.

Federated Learning: A signal processing perspective IEEE Signal Proc. Mag. (IF 15.204) Pub Date : 2022-05-06 Tomer Gafni, Nir Shlezinger, Kobi Cohen, Yonina C. Eldar, H. Vincent Poor
The dramatic success of deep learning is largely due to the availability of data. Data samples are often acquired on edge devices, such as smartphones, vehicles, and sensors, and in some cases cannot be shared due to privacy considerations. Federated learning is an emerging machine learning paradigm for training models across multiple edge devices holding local data sets, without explicitly exchanging

The Constant-Q Harmonic Coefficients: A timbre feature designed for music signals [Lecture Notes] IEEE Signal Proc. Mag. (IF 15.204) Pub Date : 2022-05-06 Zafar Rafii
Timbre is the attribute of sound that makes, for example, two musical instruments playing the same note sound different. It is typically associated with the spectral (but also the temporal) envelope and assumed to be independent from the pitch (but also the loudness) of the sound [1] . This article shows how to design a simple but effective pitch-independent timbre feature, well adapted to musical

Kalman Filtering in Non-Gaussian Model Errors: A New Perspective [Tips & Tricks] IEEE Signal Proc. Mag. (IF 15.204) Pub Date : 2022-05-06 Arman Kheirati Roonizi
It is well known that the optimality of the Kalman filter relies on the Gaussian distribution of process and observation model errors, which in many situations is well justified [1] – [3] . However, this optimality is useless in applications where the distribution assumptions of the model errors do not hold in practice. Even minor deviations from the assumed (or nominal) distribution may cause the

The Polyphase Prony Method [Tips & Tricks] IEEE Signal Proc. Mag. (IF 15.204) Pub Date : 2022-05-06 Krzysztof Duda, Tomasz P. Zieliński
Frequency and damping factor estimation, i.e., modal signal analysis, is a very important technical topic [1] – [11] . The Prony method [3] is widely used for frequency and damping estimation [4] , [5] and is quite popular, although it suffers from poor noise immunity. In this article, we present a simple-to-implement trick, without any additional computational load, that improves the noise immunity

Privacy-Preserving in-Bed Human Pose Estimation: Highlights from the IEEE Video and Image Processing Cup 2021 Student Competition [SP Competitions] IEEE Signal Proc. Mag. (IF 15.204) Pub Date : 2022-05-06 Shuangjun Liu, Xiaofei Huang, Lucio Marcenaro, Sarah Ostadabbas
Every person spends around one third of his/her life in bed. For an infant or a young toddler, this percentage can be much higher, and for bed-bound patients it can go up to 100% of their time. In-bed pose estimation is a critical step in many human behavior monitoring systems that are focused on prevention, prediction, and management of at-rest or sleep-related conditions in both adults and children

Understanding how networks of neurons process information is one of the key challenges in modern neuroscience. A necessary step to achieving this goal is to be able to observe the dynamics of large populations of neurons over a large area of the brain. Light-field microscopy (LFM), which uses a type of scanless microscope, is a particularly attractive candidate for high-speed 3D imaging. It captures

The Markov Random Field in Materials Applications: A synoptic view for signal processing and materials readers IEEE Signal Proc. Mag. (IF 15.204) Pub Date : 2021-12-28 Mary Comer, Jeff Simmons
The Markov random field (MRF) is one of the most widely used models in image processing, constituting a prior model for addressing problems such as image segmentation, object detection, and reconstruction. What is not often appreciated is that the MRF owes its origin to the physics of solids, making it an ideal prior model for processing microscopic observations of materials. While both fields know

Surfing Virtual Waves to Thermal Tomography: From model- to deep learning-based reconstructions IEEE Signal Proc. Mag. (IF 15.204) Pub Date : 2021-12-28 Péter Kovács, Bernhard Lehner, Gregor Thummerer, Günther Mayr, Peter Burgholzer, Mario Huemer
Thermographic imaging is a fast and contactless way of inspecting material parts. Usually, with model-driven evaluation procedures, lateral heat flow is ignored, and, thus, 1D reconstruction is applied to detect defects. However, to correctly size defects, the lateral heat flow must be considered, which requires a full 3D reconstruction. The 3D thermal defect imaging is a major challenge because heat

The Cramér–Rao Bound for Signal Parameter Estimation From Quantized Data [Lecture Notes] IEEE Signal Proc. Mag. (IF 15.204) Pub Date : 2021-12-28 Petre Stoica, Xiaolei Shang, Yuanbo Cheng
Several current ultrawide band applications, such as millimeter-wave radar and communication systems [1] – [3] , require high sampling rates and therefore expensive and energy-hungry analog-to-digital converters (ADCs). In applications where cost and power constraints exist, the use of high-precision ADCs is not feasible, and the designer must resort to ADCs with coarse quantization. Consequently,

The shape of a surface determines how it interacts with wireless radio-frequency signals. Taking a homogenous metal plate as an example, we can bend and rotate it in different ways to make the incident wireless signal become diffusely or specularly reflected in the desired manner.
