DOI: 10.1080/00015385.2019.1627020

Abstract: Tuberculous constrictive pericarditis is one of the most serious sequels of tuberculous pericarditis. Often this diagnosis is delayed or missed, resulting in even worse outcomes. Considering the st... read more here.

DOI: 10.1109/lsp.2023.3235647

Abstract: The focus measure is commonly used in the passive autofocus imaging system, which gives a sign of the image focus level. However, most methods are sensitive to image noise. The construction of an anti-noise focus… read more here.

DOI: 10.3788/col201917.061001

Abstract: Depth from focus (DFF) is a technique for estimating the depth and three-dimensional (3D) shape of an object from a multi-focus image sequence. At present, focus evaluation algorithms based on DFF technology will always cause… read more here.
