A reversible watermarking algorithm with high data-hiding capacity has been developed for electrocardiogram (ECG) signal based on wavelet transforms. In signal, the energy is concentrated in QRS complex waves. So selection of coefficients hiding should avoid making waves distort obviously. The hides bits expansion selected frequency sub-band Harr transform lifting scheme. Due to a slightly modification non waves, imperceptibility embedded watermark ECG well guaranteed. performance evaluated...

We present a bidirectional transformer network to exploit the long-range informative dependency both in temporal and spatial domains for video deblurring. Motivated by fact that optical flow is related latent frames rather than blurry ones degradation process, we first develop pre-deblur module generate initial so can use these estimate better exploring information. Then propose an effective explore information, where it aggregates information of whole sequence through backward forward...

Omnidirectional (or "360 degree") video, representing a panoramic view of spherical 360° ×180° scene, can be encoded using conventional video compression standards, once it has been projection mapped to 2D rectangular format. Equirectangular format is currently used for mapping 360 degree representation coding HEVC/JEM. However, in the top and bottom regions image, corresponding "north pole" "south representation, significantly warped. We propose perform rotation input prior HEVC/JEM...

In this article, an instance-based naive Bayes (INB) method is proposed to interpret out-of-control signals. By training one for classifier, considers the similar features between test instance and instances. For three benchmark examples with small number of variables, experimental results show that INB outperforms all techniques in overall average performance; cases more than two performs better most scenarios. large can be applied practical problems. This research indicates very...

A novel tetranuclear copper complex (TCC) has been successfully synthesized and characterized using high resolution mass spectrometry (HRMS), Fourier transform infrared spectroscopy (FTIR) X-ray single crystal diffraction technique. TCC was capable of triggering by Glutathione (GSH) to produce Cu (Ⅰ), then the resulted (Ⅰ) further converted overexpression endogenous H2O2 into •OH, a highly cytotoxic reactive oxygen species (ROS), thereby killing cancer cells. showed cytotoxicity 4T1, MCF7,...

Most researches treated anomalies as deviations in the overall traffic volume. However, not all of network incidents result significant volume change. Feature-based analysis enables detection that are difficult to isolate In order accurately detect anomaly, this paper proposes a methodology based on Exponentially Weighted Moving Average (EWMA). It utilizes feature entropy convenient summary statistic for distribution's tendency be concentrated or dispersed. Then, it predicts normal by and...

Electrical discharge machining (EDM) is an effective method to process micro-hole for electrically conductive materials regardless of the hardness. However, accuracy and cost are greatly affected by EDM parameters, which slight fluctuations in actual process. In view this, reliability-based design optimization (RBDO) introduced balance electrode wear aperture gap when unavoidable uncertainties considered. Kriging model trained inherited Latin hypercube (ILHD) expected feasibility function...

Video deblurring is a challenging task since the blur caused by camera shake, object motions, etc. The success of state-of-the-art methods stems mainly from exploiting temporal information neighboring frames through alignment. When there exists occlusion among sequence, these approaches become less effective for inaccurate In this paper, we propose an occlusion-aware network to handle video deblurring. proposed module first generates coarse pixel-wise alignment filter explore and then learns...

Linear wireless sensor networks are characterized by a linear topology and multihop forwarding patterns. Sensors closer to the base station usually required forward large amount of traffic for sensors farther from station, leading environment cannot be effectively monitored. The energy consumption balance is achieved in paper adjusting distance between nodes. nodes near become short because they have more traffic. node deployment converted optimization problems distribution network lifetime...

Pre-/post-processing filters obtained from lapped transforms achieve higher coding efficiency by exploiting transform block boundary correlation. Existing approaches however do not explicitly consider the impact of pre-filtering on prediction efficiency, thereby resulting in a lower overall rate-distortion performance. We present framework where are designed with an objective function based model. The post-filter is constructed so as to reverse pre-filter processing at decoder. show how...
