Performance Improvement in Noisy Image Enhancement

Performance improvement of text-independent speaker verification systems based on histogram enhancement in noisy environments

In this paper a histogram enhancement technique is presented in order to improve the robustness of text-independent speaker verification systems. The technique transforms the features extracted from speech such that the contrast of their histogram is enhanced. Experiments showed significant improvements for this technique compared to standard techniques both in clean testing environments, and i...

Image quality enhancement in digital panoramic radiograph

One of the most common positioning errors in panoramic radiography is palatoglossal air space above the apices of the root of maxillary teeth. It causes a radiolucency obscuring the apices of maxillary teeth. In the case of this positioning error, the imaging should be repeated. This causes the patient be exposed to radiation again. To avoid the repetition of exposing harmful X-rays to the pati...

Quality improvement in manufacturing through human performance enhancement

In the increasingly competitive global economy, survival of an industry depends on catering to customer needs by quickly producing quality products and providing quality service at an affordable price. In production, or in service, ergonomic considerations have manifested themselves in two distinct, yet related, domains. Focuses on the humans who contribute to product manufacture/service. It is...

Noisy Speech Intelligibility Enhancement

This paper addresses the study of the speech intelligibility enhancement. The speech model, noise sources, perceptual aspects of speech, and performance evaluation are reviewed. The intelligibility enhancement system based on spectral subtraction technique is investigated. Spectral density estimation device based on the algorithm of smoothed periodograms is analysed. Determination of the silenc...
