However, there is no clear evidence yet that this does not come at the price of less generalization to conditions that were not present during training. On the other hand, acoustic modeling with Reservoir Computing (RC) did not offer improved clean speech recognition but it leads to good robustness against noise and channel distortions. In this paper, the aim is to establish whether adding feature denoising in the front-end can further improve the robustness of an RC-based recognizer, and if so, whether one can devise an RC-based Denoising Auto Encoder that outperforms a traditional denoiser like the ETSI Advanced Front-End. In order to answer these questions, experiments are conducted on the Aurora-2 benchmark.","PeriodicalId":88960,"journal":{"name":"Proceedings of the ...

In this paper, the face images at different distances are simulated by varying image scales (resolutions). The performances of three face recognition algorithms (matchers) are tested with variant image scales (simulating different distances) and with two spectral images (modalities). The three selected matchers are face pattern byte, elastic bunch graph matching, and linear discriminant analysis; while the two modalities are visible and thermal images. The performance of a face recognition system can be measured by accuracy (AC) rate and false accept rate (FAR). To enhance the performance of face recognition especially at a distance, score fusion techniques are applied, which combine several scores from multiple matchers and multiple modalities. Our experiments are conducted with the ASUMS face dataset consisting of two spectral images (visible and thermal) from 135 subjects. The experimental results show that the face recognition with small image scales (simulating long distances) have low performance (e.g., AC=91.36%, FAR=8.64% for 20×20-pixel images); and score fusion can greatly improve accuracy (99.34%) meanwhile reduce FAR (0.31%).","PeriodicalId":88960,"journal":{"name":"Proceedings of the ...

Along with the benefits come considerable threats to users' privacy, as these enhanced services operate on private sensitive information, such as the true identity and location of users. This paper proposes a lightweight, distributed anonymity and location privacy service which can be deployed on mobile embedded systems (e.g. smart clothing, smart phones), even heterogeneous in nature, allowing users to form communities which help them hide their identities and exact location. Acting as a proxy the proposed service can sanitize users' requests prior to forwarding them to a location-based service (LBS). The deployment of this type of information sanitization proxy would facilitate the wider adoption of the new generation of enhanced reality applications and services, alleviating the justified concerns regarding users' privacy.","PeriodicalId":88960,"journal":{"name":"Proceedings of the ...

The key step is to use the subaperture approach in the SRC algorithm. First, the original signals are divided into subapertures in the azimuth direction of the time domain to image independently, and then the sub-bands of the frequency domain are combined to form the final SAR image. The method reduces coupling in the range and azimuth direction of the echo signal under the squint imaging mode, and addresses the problems of squint SAR in near space including overlong synthetic aperture and motion error. Simulation through point targets demonstrates the improvement in azimuth resolution, ISLR and PSLR, which verifies the effectiveness of this proposed SSRC algorithm in near space squint SAR imaging.","PeriodicalId":88960,"journal":{"name":"Proceedings of the ...

We also define associated performance metrics by modeling the mode selection problem as a hypothesis test with Gaussian distribution. Furthermore we provide the analytical expressions for correct detection, false alarm, and missed detection probabilities.

This scheme uses non-negative matrix factorization (NMF) as the feature of the image on the secondary image obtained by the ring partitioning of the original one. The image hash is rotation-invariant with arbitrary degree but it is robust against acceptable content-preserving image modifications. We re-visit the algorithm and show that the algorithm tolerates some serious security flaws. Ignoring specific areas of the image in the feature extraction stage and invariance against individual ring rotation are two existing drawbacks. Practical experiments show the mentioned weaknesses and some solutions will be proposed.","PeriodicalId":88960,"journal":{"name":"Proceedings of the ...

This paper presents a novel approach to individual identification based on a new biometric modality Transient Evoked Otoacoustic Emission (TEOAE), which is a low level acoustic signal generated by human cochlea and detected in the outer ear canal. We resort to wavelet analysis to derive the time-frequency representation of such non-stationary signal and machine learning techniques: linear discriminant analysis and softmax regression to accomplish pattern recognition. We also introduce a complete framework of the biometric system considering practical application. Experiments on a TEOAE dataset of biometric setting show the merits of the proposed method.
