Focus stacking is an effective approach to extending the depth of field of a camera, yet is challenging with regard to 1) controlling focal planes in forming a stack and 2) fusing the focal stack into composites that are free from defocusing, i.e., all-in-focus. 

The IEEE Signal Processing Society Boston Chapter has been selected as the recipient of the 2022 Chapter of the Year Award!

While message-passing neural networks (MPNNs) are the most popular architectures for graph learning, their expressive power is inherently limited. In order to gain increased expressive power while retaining efficiency, several recent works apply MPNNs to subgraphs of the original graph.

Greetings to everyone as we prepare to celebrate the 75^th anniversary of SPS during 2023! Membership of SPS, or any group, is based on the relationships, built between members. The IEEE Signal Processing Society has observed that sustained relationships lead to sustained membership growth. In its efforts to build a large and strong base of membership, SPS has spent the past few years focusing its attention on Student Members. 

Brain data are inherently large scale, multidimensional, and noisy. Indeed, advances in imaging and sensor technology allow recordings of ever-increasing spatio-temporal resolution. Multidimensional, as time series data are recorded at multiple locations (electrodes, voxels), from multiple subjects, under various conditions.

As an authentication method, biometrics offer unparalleled convenience and security. With very little for users to remember and do, there is also very little that they can do incorrectly, thus limiting the attack surface of an authentication system. Unfortunately, biometrics also present a challenging privacy/security tradeoff: biometric data...

Dr. Li is a Singaporean scientist, and a Chinese Teochew native. He is now a Presidential Chair Professor at the School of Data Science, The Chinese University of Hong Kong, Shenzhen, China. He did his Ph.D in digital signal processing of speech in 1990, and spent the past three decades to refine the technology. 

As the most widely-used spatial filtering approach for multi-channel signal separation, beamforming extracts the target signal arriving from a specific direction. We present an emerging approach based on multi-channel complex spectral mapping, which trains a deep neural network (DNN) to directly estimate the real and imaginary spectrograms of the target signal from those of the multi-channel noisy mixture.
