This work investigates the performance improvements achievable throug... Numerical modeling and measurement by pulsed television holography of ultrasonic displacement maps in plates with through-thickness defects [作者：Lopez-Vazquez, JC; Dean-Ben, XL; Trillo, C; Doval, AF; Fernandez, JL; Amlani, F; Bruno, OP,期刊：OPTICAL ENGINEERING, 页码：95802-95802 , 文章类型： Article，,卷期：2010年49-9] We present a novel numerical modeling of ultrasonic Lamb and Rayleigh wave propagation and scattering by through-thickness defects like holes and slots in homogeneous plates, and its experimental verification in both nea... Holographic encryption system in the Fresnel domain with convergent random illumination [作者：Kumar, P; Joseph, J; Singh, K,期刊：OPTICAL ENGINEERING, 页码：95803-95803 , 文章类型： Article，,卷期：2010年49-9] A secure holographic system is proposed, based on the principle of two-wave encryption in the Fresnel domain under convergent random illumination. The convergent random wavefront, instead of the commonly used plane wavef... New adaptive and progressive image transmission approach using function superpositions [作者：Leni, PE; Fougerolle, YD; Truchetet, F,期刊：OPTICAL ENGINEERING, 页码：97001-97001 , 文章类型： Article，,卷期：2010年49-9] We present a novel approach to adaptive and progressive image transmission, based on the decomposition of an image into compositions and superpositions of monovariate functions. The monovariate functions are iteratively ... Mixed impulse and Gaussian noise removal using detail-preserving regularization [作者：Zeng, XY; Yang, LH,期刊：OPTICAL ENGINEERING, 页码：97002-97002 , 文章类型： Article，,卷期：2010年49-9] Over the years, numerous methods have been proposed separately for restoring images corrupted by either impulse noise or Gaussian noise. Nevertheless, because of the distinct nature of both types of degradation processes... Discovering objects and their location in videos using spatial-temporal context words [作者：Sun, H; Wang, C; Wang, BL; El-Sheimy, N,期刊：OPTICAL ENGINEERING, 页码：97003-97003 , 文章类型： Article，,卷期：2010年49-9] We present a novel unsupervised learning algorithm for discovering objects and their location in videos from moving cameras. The videos can switch between different shots, and contain cluttered background, occlusion, cam... Mel-cepstral feature extraction methods for image representation [作者：Cakir, S; Cetin, AE,期刊：OPTICAL ENGINEERING, 页码：97004-97004 , 文章类型： Article，,卷期：2010年49-9] An image feature extraction method based on the two-dimensional (2-D) mel cepstrum is introduced. The concept of one-dimensional mel cepstrum, which is widely used in speech recognition, is extended to 2-D in this articl... Copyright protection scheme for still images based on an image pinned field [作者：Lee, MT; Chang, HT,期刊：OPTICAL ENGINEERING, 页码：97005-97005 , 文章类型： Article，,卷期：2010年49-9] Watermark embedding processes usually result in some degradation of the digital multimedia contents. Hence, they are not suitable for valuable and sensitive digital multimedia contents. Therefore, schemes combining signa... Robust high-definition video watermarking based on self-synchronizing signals against composite distortions [作者：Oh, TW; Lee, MJ; Kim, KS; Lee, HK; Lee, HY,期刊：OPTICAL ENGINEERING, 页码：97006-97006 , 文章类型： Article，,卷期：2010年49-9] This paper proposes a high-definition video watermarking method robust against compound geometrical attacks by camcorder capture as well as common video processing such as frame-rate conversion and transcoding. Unlike tr... Simulation scheme of dusk scene using piece-wise multiple regression based on time-series color-block images [作者：Liu, CC; Yang, CC,期刊：OPTICAL ENGINEERING, 页码：97007-97007 , 文章类型： Article，,卷期：2010年49-9] Dusk and dawn are usually the most beautiful moments of the day, and are almost always too short for busy people nowadays to witness their coming. In this work, an efficient strategy for simulating a dusk scene of an out... Single-image motion deblurring using adaptive anisotropic regularization [作者：Hong, H; Park, IK,期刊：OPTICAL ENGINEERING, 页码：97008-97008 , 文章类型： Article，,卷期：2010年49-9] We present a novel algorithm to remove motion blur from a single blurred image. To estimate the unknown motion blur kernel as accurately as possible, we propose an adaptive algorithm using anisotropic regularization. The...
