Abstract One of the primary purposes seismic stratigraphy is to evaluate components layer relationships within a depositional chronology. Prestack images contain wealth information, such as variations in offset and azimuth event, naturally produce higher-resolution facies analysis results than poststack data. However, prestack data usually suffer from potential unreliability issues due low sign...

In precision machining, the milling tool’ geometry has a great influence on milled surface quality. The research tool state monitoring was mainly based one-dimensional signals and two-dimensional images, which could indirectly obtain wear area, but it not provide volume of breakage thereby making difficult to achieve quantitative analysis wear. This paper proposed three-dimensional (3D) reconst...

Wavelets and their associated transforms are highly efficient when approximating and analyzing onedimensional signals. However, multivariate signals such as images or videos typically exhibit curvilinear singularities, which wavelets are provably deficient of sparsely approximating and also of analyzing in the sense of, for instance, detecting their direction. Shearlets are a directional repres...

Over the recent years, volume of medical images and related digital records, called electronic generated, shared, stored by different intelligent devices, sensors, Internet things networks, to name a few, has drastically increased. Such records are shared cloud providers for storage further processing. However, an increasingly serious concern is illegal copying, modification, forgery records. T...

Traditional noise removal methods like Non-Local Means create spurious boundaries inside regular zones. Visushrink removes too many coefficients and yields recovered images that are overly smoothed. In Bayesshrink method, sharp features are preserved. However, PSNR (Peak Signal-to-Noise Ratio) is considerably low. BLS-GSM generates some discontinuous information during the course of denoising a...

Reversible Data Hiding (RDH) is the process of transferring secret data hidden inside cover media to recipient so can securely retrieve both and media. The RDH approach applied in this study field telemedicine, medical-secret conveyed privately via medical video. Morse code-based encryption technique tends encrypt by compression using Arithmetic coding technique. Discrete Shearlet transform (DS...
