Face detection is the most basic processing in the face recognition process. If the detection method is not appropriate, it can cause the recognition process to collapse. Face detection is very important in face recognition. The facial pattern is very complex and susceptible to external interference. Common facial detection algorithms generally have weaknesses such as high computational complexity, slow speed, and high false alarm rates. In this paper, a skin color model detection method based on the YCbCr color space is used for facial detection, which solves the problem of high computational complexity. Morphological theory is also used for subsequent image processing. © 2024 SPIE.

EEG signals can be considered a secure and safe way to capture human brain activity. EEG signals can play a vital role in motor imagery applications to control hands, feet, etc. Brain computer interface (BCI) is method of connecting human brain to laptop or computer. To control the movement of hands and feet, a BCI system is required. The generated EEG signal is read via computer and, as per EEG signal command, is set for motory movement of the hand and feet. Therefore, in motor imagery EEG applications, proper classification of the EEG signal is desired to distinguish hand and foot movements. In this work, an EEG signal classification is done using Deep Neural Networks (DNN) method and the results are compared with recent notable methods.

Today, the increasingly complex external environment and the goal of building a harmonious society have put forward higher requirements for security check work. Traditional security inspection methods are facing enormous challenges. With the maturity of intelligent security technology, Intelligent security inspection has become a trend. Security check that requires both reasoning speed and accuracy, this paper proposes a lightweight target detection network, which takes YOLOX as the overall framework and Mobilenet-V3 as the backbone network. The effectiveness of the network is proved by the simulation experiment on the public data set OPIXray and can achieve a real-time computing speed of 87.7FPS. © 2022 SPIE.

Recent researches have proven that deep denoising autoencoder is an effective method for noise reduction and speech enhancement, and can provide better performance than several existing methods. However, training deep denoising autoencoder has proven to be difficult computationally. The goal of this study is to develop a modular approach for training deep denoising autoencoders as a set of classifiers based on collaborative learning. Each classifier is a multilayer deep denoising autoencoder network and specialized for a particular enhancement task and handles a subset of the complete training dataset. The approach performance was assessed using a perceptual evaluation of speech quality and the segmental signal-to-noise ratio. We have trained two individual DDAEs with three and five hidden layers respectively for comparison purposes. We have also compared our proposed model with the traditional spectral subtraction and, log MMSE methods. The results showed that DDAE with three and five hidden layers was sufficient (deeper is better), while the proposed approach provided higher intelligibility results and was more suitable for high-quality cases. © 2022 IEEE.

Passive brain-computer interface (BCI) based on electroencephalographic (EEG) signals show promise for monitoring human vigilance in critical settings that continuously strain human attention. However, the lack of extensive public datasets limits progress in artificial intelligence research. To overcome this problem, we implemented generative adversarial networks (GANs) to augment existing EEG datasets. We focused on two datasets: a publicly available resting-state dataset and a custom one simulating industrial activities. After extracting time-variant alpha indices using continuous wavelet transform, we compared the generated data with real data using the L2 distance metric and autocorrelation function. We additionally assessed two forecasting models trained on original and augmented datasets, comparing their predictions. The integration of synthetic data led to an improvement in signal behavior prediction, as evidenced by a 32% reduction in mean absolute error for the resting-state dataset. Furthermore, a metric inspired by the Frechét Inception Distance was computed using the forecasting model to discern the distributions of embeddings for the real and generated data, with results showing a strong resemblance between the two. This study challenges the limitation of acquiring domain-specific EEG data and aims to develop a robust signal generation framework. © 2024 IEEE.

Skin disorders are the most frequent health problems that people face around the world, and they come with a hefty price tag. Chickenpox, impetigo, infectious erythema, scabies, and skin warts are chronic and incurable skin disorders that cause severe morbidity in the form of physical discomfort. The technique of image processing is used in our procedure of identifying skin problems. Because this approach is based on Deep Convolutional Neural Network Learning, extremely precise results can be obtained by employing these techniques. The patient submits a photo of the affected area of the skin to the prototype as an input. In this photograph, the Deep Learning technique is employed, and as a result, the discovered skin disease is displayed as the output. © 2022 IEEE.

Speech is the most convenient communication mode. Speech signal, while transmission degrades due to various factors such as white noise addition, noise from the surrounding environment, etc. Wind noise gets added in mobile phones and corrupts speech signals leading to listener's fatigue. Speech enhancement is a research area focusing on improving the quality and intelligibility of degraded speech signals. Wind noise, being non-stationary, is difficult to remove. This work focuses on reducing the effect of wind noise using various speech enhancement algorithms such as Multi-band Spectral Subtraction, Minimum Mean Square Error Short-Time Spectral Amplitude (MMSE-STSA), MMSE log STSA and Wiener filtering. The experiments are conducted considering wind noise alone and in combination with white noise. The performance of these speech enhancement algorithms on wind noise is evaluated using measures such as overall SNR, segmental SNR, Perceptual Evaluation of Speech Quality (PESQ), Itakura Saito Spectral distance and Short-Time Objective Intelligibility (STOI). © 2022 IEEE.

The homomorphic encryption algorithm Paillier is a cryptographic method that can be applied in areas such as privacy-preserving computation and federated learning. However" due to the inherent complexity and computational overhead of the algorithm, it may affect real-time requirements when dealing with a large volume of encrypted data. In this paper, we propose a method to improve the efficiency of the encryption algorithm by combining GPU parallel processing technology with homomorphic encryption. Through experiments on encrypting and decrypting plaintexts of different sizes, the results show that the introduction of GPU significantly improves the encryption and decryption speed Compared with other parallel processing methods" the acceleration effect of our proposed method is more significant. © 2023 IEEE.

Addressing the issues of excessive redundant nodes, non-smooth paths, and low search efficiency in the path planning process of the traditional A∗ algorithm, this paper proposes an improved Dynamic Expansion Neighborhood A∗ algorithm for optimal path planning. Firstly, building upon the traditional A∗ algorithm, the search neighborhood is dynamically expanded by combining the 8-neighbor and 24-neighbor search algorithms, dynamically adjusting the search scope to reduce redundant nodes. Secondly, through modification of the heuristic function, introducing weights, and optimizing the estimation function to enhance path search efficiency. Finally, the obtained path is subjected to smoothing processing to eliminate corner sharp points, improving path smoothness. Simulation results demonstrate that the improved A∗ algorithm outperforms the traditional algorithm in terms of length, node count, and smoothness of the planned path. © 2023 IEEE.
