Secret Image Sharing Based on Encrypted Pixels
IEEE Access, 2018 The well-known Thien and Lin's (k, n) secret image sharing (SIS) scheme and its extended versions are threshold schemes, in which a secret image is shared among n shadow images and it can be recovered from any k shadow images.

Arthritis Care &Research, EarlyView.Objective Foot orthoses are thought to improve pain by potentially modifying internal mechanical forces. To test this, we explored whether foot orthoses can modify patterns of bone marrow lesions (BMLs) in people with midfoot pain. Methods Forty‐two people were recruited with midfoot pain, and magnetic resonance imaging–confirmed midfoot BMLs ...

Systematic approach to nonlinear filtering associated with aggregation operators. Part 2. Frechet MIMO-filters [PDF]
, 2017 Median filtering has been widely used in scalar-valued image processing as an edge preserving operation. The basic idea is that the pixel value is replaced by the median of the pixels contained in a window around it.

Prototype high angular resolution LEKIDs for NIKA2
, 2018 The current resolution of the NIKA2 260 GHz arrays is limited by the $1.6\times 1.5 mm^2$ inductor size on the individual pixels. In view of future updates of the instrument, we have developed a prototype array with smaller pixels that is experimentally ...

The Astronomical Journal, 2010 The third US Naval Observatory (USNO) CCD Astrograph Catalog, UCAC3 was released at the IAU General Assembly on 2009 August 10. It is a highly accurate, all-sky astrometric catalog of about 100 million stars in the R = 8 to 16 magnitude range. Recent epoch observations are based on over 270,000 CCD exposures, which have been re-processed for the UCAC3 ...

Memristor-Based Edge Detection for Spike Encoded Pixels
Frontiers in Neuroscience, 2020 Memristors have many uses in machine learning and neuromorphic hardware. From memory elements in dot product engines to replicating both synapse and neuron wall behaviors, the memristor has proved a versatile component. Here we demonstrate an analog mode

Advanced Engineering Materials, EarlyView.Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

Fusion of Weighted Mean Reconstruction and SVMCK for Hyperspectral Image Classification
IEEE Access, 2018 Conventional classifiers treat hyperspectral image (HSI) as a list of spectral measurements without considering the spatial relationship between pixels. Therefore, these methods discard the information associated with spatial correlations among distinct ...

Advanced Engineering Materials, EarlyView.Excellent combinations of strength and impact toughness are obtained in a bilayer composite of high‐strength carbide‐free bainitic (CFB) steel and high‐ductility twinning‐induced plasticity (TWIP) steel. The composite absorbs energy at small strains when the notch is placed on the TWIP side and at high strains when the notch is placed on the CFB side ...

Planning with Pixels in (Almost) Real Time
, 2018 Recently, width-based planning methods have been shown to yield state-of-the-art results in the Atari 2600 video games. For this, the states were associated with the (RAM) memory states of the simulator.
