Acoustic Hear-Through (HT) or acoustic transparent transmission technique is used to enable natural listening of ambient sounds while wearing headphones. Based on the structure of in-ear headphones with active noise cancellation, this paper presents the design of an acoustic HT digital filter and embeds the headphone system with HT function. Combined with the speech spectral subtraction algorithm, the speech enhancement is applied based on the HT system to achieve selective HT of noisy speech. Compared with the acoustic transfer functions in the natural listening environment and the no HT headphone-wearing environment, the proposed HT headphone performs well in reducing the attenuation of the headphone system. Finally, the idea that the proposed selective HT function has great potential to improve the quality and intelligibility of the noisy speech heard by the eardrum is verified.","PeriodicalId":330562,"journal":{"name":"2022 14th International Conference on Signal Processing Systems (ICSPS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131304956","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on the idea of PCANet model, we construct a multiscale space to calculate across-scale local differences of expression images to obtain the holist and local information. Then, we implement L1-norm PCA to learn the convolution filters of two stages from the across-scale local differences. Afterwards, we encode the output images by binary hash and concatenate all the block-wise histograms to form expression features. Finally, we employ support vector machine (SVM) with linear kernel for classification. Extensive experiments are conducted on both controlled and uncontrolled expression databases, including CK+, JAFFE, ISED and BAUM-2i.

In order to mitigate the impulsive noise, a new direction finding method-global median value filtering method has recently been proposed, which exploits the characteristic that the impulsive noise appears with randomness. However, this algorithm can not detect more sources than the number of sensors. In this paper, a median filtering method based on non-circular signals is proposed, and it is extended to nested array scenarios, which expands the virtual array aperture and improves the number of estimated sources and DOA estimation performance. Then the traditional second order moment DOA estimation method can be used to process the covariance matrix of the filtered received data. To further reduce the computational complexity of this algorithm, the reduced dimensional MUSIC (RD-MUSIC) method is introduced for DOA estimation. Simulation results show that the method has better DOA estimation performance than existing methods, especially in the strong impulsive noise environment.","PeriodicalId":330562,"journal":{"name":"2022 14th International Conference on Signal Processing Systems (ICSPS)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120991364","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The existence of ground clutter and sea clutter, mutual interference in the detection of slow and high-velocity targets, azimuth Doppler folding of moving targets, range cell migration and other problems lead to serious defocusing of high-speed moving targets, which is difficult to effectively detect in SAR image. Ultimately, these lead to the difficulty of motion parameter estimation and imaging. Therefore, when the traditional SAR imaging algorithm is used to image the moving target of the spaceborne SAR, the target is usually in a defocused state, which leads to the degradation of the detection performance. In this paper, combined with the BP algorithm, a spaceborne SAR moving target detection algorithm based on two-dimensional velocity (range velocity and azimuth velocity) search is designed to match the Doppler parameters. After realizing the ergodic focusing of the moving target at a uniform speed, target detection is followed. Then the detection probability and imaging quality of the moving target can be improved by comparing the associated amplitude values at different search speeds. The simulation results verify the feasibility and effectiveness of the algorithm.","PeriodicalId":330562,"journal":{"name":"2022 14th International Conference on Signal Processing Systems (ICSPS)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131892465","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we propose a multi-view SAR image recognition method based on a bidirectional convolutional long and short term memory (Conv-LSTM) network. Firstly, we use a Log-Gabor filter to extract angle-stable monogenic features to reduce inter-class differences. Secondly, feature dimensionality reduction is performed using a multilayer perceptron (MLP) network. Finally, a bidirectional LSTM network is used to integrate the SoftMax classifier for target recognition.
