Bringing Multiresolution Signal Processing Principles into Machine Learning / Deep Learning

Abstract: Multiresolution analysis (MRA) can be considered a powerful tool, for analyzing non-stationary and transient signals. MRA has wide applications in computer vision, transient and edge detection, medical imaging, image coding/compression, de-noising, sparse signal processing, biomedical signal processing, biometrics, radar and communications, pitch estimation and geophysics. Wavelets lead to a multiresolution analysis of signals. MRA has been found to perform well in pattern recognition applications. Due to evolving technology, exponential growth in computation facilities, and availability of big databases, Deep Learning (DL) algorithms have been extensively used in pattern recognition tasks. In MRA, wavelet functions are applied to 1D or 2D signals to extract features. At first glance, MRA and DL techniques appear disjoint. However, empirically it is observed in many applications, that when both MRA and DL techniques are combined, they produce better results than the methods which employ DL techniques directly without employing MRA. 

This talk will focus on the recent development in the field of MRA and applications, wherein MRA and DL can be combined, to exploit the benefits of both. In particular, the first part of the talk will discuss the recent developments of MRA along with DL techniques in touch-less biometrics for fingerprint matching, iris and ear recognition. The wavelet scattering network has been employed, with encouraging results.

In the second part of the talk, we will discuss a new flexible and versatile method, based on a deep learning architecture and augmentation technique, for a rotation invariant automatic ear recognition system. A convolutional neural network is trained with a set of manually generated data points. We have used geometric transformations that include rotation, flipping and zooming method to generate artificial data points, to increase the training images. We also explore the performance of different data augmentation techniques, for limited data ear recognition. The results are very encouraging, up to 45o rotation of ear images. The accuracy of the proposed model and their comparison with other models in terms of Model accuracy, Model loss and so on will also be discussed in the talk.

Deep neural networks in multimedia watermarking

Abstract: A digital watermark is an invisible or inaudible signal embedded into multimedia data that can in an undisputable manner identify the author, owner, or distributor of data. Over 20 years of development, we have obtained some useful tools for this purpose. From our point of view, the watermark must be robust to changes that are not deteriorating data quality in a significant manner. Such changes are commonly referred to as attacks.

Recently, deep neural networks (DNNs) development improved results in numerous fields of signal processing. Many benchmark results are surpassed by the application of the DNNs. The DNNs are used for developing forgeries of multimedia data (deepfakes) and for breaching security in various fields. However, the current improvement of the digital watermarking techniques by DNNs is moderate. So we are now in 

a paradoxical situation: the DNNs are successfully used to attack the digital watermarking and related systems, while the digital watermarking techniques are not significantly improved using these means.

In this presentation, we are going to describe the most recent development in the DNN application to digital watermarking. The developed system jointly trains two networks: embedder and detector. Different and varying weights are associated with these two networks in the training phase to ensure imperceptibility and detectability of the watermark. To ensure robustness to attacks, we have added a set of layers with attacks between embedder and detector network. These layers are not trainable, but are required in order to determine the corresponding gradient function for propagation within the network. Attack layers have free setup parameters which are set manually. Procedure for training with attack layers should be carefully designed to preserve convergence of network and other desirable network features. This is especially important for desynchronization attacks that are particularly difficult to be handled with DNNs. Namely, these attacks tend to change the number of available samples while the DNNs work the best with fixed-size input. We are in the process of overcoming all of these issues in our research giving excellent levels of imperceptibility and robustness to all major classes of attacks. Note that our technique is developed for signals mapped to the time-frequency domain, which is the difference from classical DNN-based approaches championed by processing raw data.

Experience in research and development of a vehicle identification system using RFID and broadband wireless networks

Abstract:  Radio Frequency Identification (RFID) technology finds its application in many areas, including vehicle identification, logistics, production control, access control, payment services. One of the promising areas of RFID use is vehicle identification. Currently, CCTV cameras are used to solve this problem. Systems for automatic registration of traffic violations make it possible to reduce the number of accidents in which more than 15,000 people die every year in Russia, and huge material damage is caused. However, the cameras' effectiveness can be reduced to 50% or less in bad weather conditions. An effective way to eliminate this shortcoming is to equip car license plates with RFID tags and receive identification numbers over the air using RFID readers placed alongside the cameras. As the experiments show, this method of vehicle identification can provide an efficiency of up to 95% even in bad weather conditions. The timeliness and relevance of creating automated safety systems on roads using RFID technology are emphasized in the decree of the Russian Federation Government on the creation of pilot zones of such systems in Moscow, St. Petersburg, and Kazan in 2022-2024.

Developing and implementing an RFID system for vehicle identification requires solving many new complex scientific and engineering problems. This report presents an overview of the results obtained by the authors over several years of research and implementation of RFID systems for vehicles identification. We present the original results of analytical and simulation modeling of the system, showing the dependence of the probability of successful identification on the speed of vehicles with the RFID tags mounted on license plates. The models consider various settings of RFID readers, tag parameters, multipath propagation of radio signals, and the Doppler effect. The report also presents an overview of the distributed software system architecture, developed under the guidance and participation of the report's authors. This system was used in pilot implementations of the system.
A large-scale experiment in Kazan, where about 1000 vehicles were equipped with RFID tags, showed that successful identification probability reached 95%. In the pilot implementations of the system in 2020-2021 in Kazan and on the Central Ring Road in Moscow Region, readers developed at the ICS RAS and vehicles license plates with RFID tags produced by PJSC «Mikron» were used.
At the end of the report, we discuss the prospects for further development and implementation of RFID systems for vehicles identification and highlight the key problems and possible solutions.
