When video is shot in noisy environment, the voice of a speaker seen in the video can be enhanced using the visible mouth movements, reducing background noise. While most existing methods use audio-only inputs, improved performance is obtained with our visual speech enhancement, based on an audio-visual neural network. We add to the training data videos with synthetic background noise taken fro...

In this paper, we introduce a non-linear enhancement technique called Audio-Visual Codebook Dependent Cepstral Normalization (AVCDCN) and we consider its use with both audio-only and audio-visual speech recognition. AVCDCN is inspired from CDCN [1] [2], an audio-only enhancement technique that approximates the non-linear effect of noise on speech with a piece-wise constant function. Our experim...

Satellite images are being used in numerous fields of aspects. The major controversy of various types of images is their resolution. In this paper, proposed a new satellite image resolution enhancement technique based on the interpolation of the high frequency sub bands obtained by discrete wavelet transform and the input image. The proposed declaration intensification technique uses DWT to dec...

An image resolution enhancement technique based on interpolation of the high frequency subband images obtained by discrete wavelet transform (DWT) and the input image. The edges are enhanced by introducing an intermediate stage by using stationary wavelet transform (SWT). DWT is applied in order to decompose an input image into different subbands. Then the high frequency subbands as well as the...

The effect of progesterone and testosterone on interferon production and on the viral infection-enhancing (VIE) activity of estrone and hydrocortisone was investigated. Neither hormone interfered with interferon production. Progesterone reduced the VIE activity of estrone but not that of hydrocortisone. Testosterone had no effect on the VIE activity of either hormone. It is concluded that the l...

AIMS Conventional computed tomography (CT) approaches provides limited visualization of the entire endoluminal changes of aortic dissection (AD), which is essential for its treatment. As an important supplement, three-dimensional CT virtual intravascular endoscopy (VIE) can show relevant details. This study aims to determine the value of VIE in displaying the entry tear and intimal flap of AD. ...

In this study, the researcher chose three different vocabulary techniques (Visual Representation, Textual Enhancement, and Glossing) and compared them with traditional method of teaching vocabulary. 80 advanced EFL Learners were assigned as four intact groups (three experimental and one control group) through using a proficiency test and a vocabulary test as a pre-test. In the visual group, stu...

Underwater images are widely used in ocean resource exploration and environment surveillance. However, due to the influence of light attenuation noise, underwater usually display degradation phenomena such as blurring color deviation; an enhancement method is required make more visible. Currently, there two major approaches for image enhancement: traditional methods based on physical or non-phy...
