The human hand has been used in art from the very beginnings, starting with stunning examples in Neolithic cave paintings. Early examples of the fist in graphic art can be found at least as far back as 1917 [1], with another example from Mexico in 1948 [2]. Fist images, in some form, were used in numerous political graphic genres, including the French and Soviet revolutions, the United States C...

Novel approach method for the reduction of compression artifact for MPEG–2 moving pictures is proposed. Total Variation (TV) regularization method, and obtain a texture component in which blocky noise and mosquito noise are decomposed. These artifacts are removed by using selective filters controlled by the edge information from the structure component and the motion vectors. Most discrete cosi...

Low-dose computed tomography reconstruction is an important issue in the medical imaging domain. Sparse-view has been widely studied as a potential strategy. Compressed sensing (CS) method has shown great potential to reconstruct high-quality CT images from sparse-view projection data. Nonetheless, low-contrast structures tend to be blurred by the total variation (TV, L1-norm of the gradient im...

Osteomyelitis is a bacterial disease that can become chronic, and treatment often includes a surgical operation to remove infected bone. The aim of this study was to develop and investigate in vitro bone filling composite materials that release ciprofloxacin to kill any remaining bacteria and contain bioceramic to help the bone to heal. Three composites of poly(L-lactide-co-ε-caprolactone), β-t...

Knowledge of carbon content in retained austenite (RA) with different neighbouring phases is essential to understand the chemical stability of RA, which is useful for microstructure tuning of transformation-induced plasticity (TRIP) steels. The present study investigates different morphologies and chemical compositions of RA by correlating electron backscattering diffraction, transmission elect...

This paper proposes a new variational model for joint multiplicative denoising and deblurring. It combines a total generalized variation filter (which has been proved to be able to reduce the blocky-effects by being aware of high-order smoothness) and shearlet transform (that effectively preserves anisotropic image features such as sharp edges, curves and so on). The new model takes the advanta...

Chao-Chung Cheng (SID Student Member) Chung-Te Li Liang-Gee Chen Abstract — With the maturation of three-dimensional (3-D) technologies, display systems can provide higher visual quality to enrich the viewer experience. However, the depth information required for 3-D displays is not available in conventional 2-D recorded contents. Therefore, the conversion of existing 2-D video to 3-D video bec...

Microbialites found in the low-light-intensity, hypersaline waters of Storr's Lake (SL), San Salvador Island, the Bahamas, were investigated with respect to their morphology, mineralogy, and microbial diversity. Previously described microbialite morphologies, as well as a newly identified "multi-cuspate" morphology, were observed at various depths. Electron microscopy analysis revealed the pres...

Poly(ester amide)s are an emerging group of biodegradable polymers that may cover both commodity and speciality applications. These polymers have ester and amide groups on their chemical structure which are of a degradable character and provide good thermal and mechanical properties. In this sense, the strong hydrogen-bonding interactions between amide groups may counter some typical weaknesses...
