Colors in a scene change under different illuminants. By adopting models that are used to describe human color constancy, the maximum-spectral-value method is proposed to estimate the illuminant from the maximum distribution of reflected lights in an image. From the experimental results, the proposed method recovers colors well with different illuminants.
Ex vivo generation of megakaryocytes from hematopoietic stem cells (HSCs) is crucial to HSC research and has important clinical potential for thrombocytopenia patients to rapid platelet reconstruction. In this study, factorial design and steepest ascent method were used to screen and optimize the effective cytokines (10.2 ng/ml TPO, 4.3 ng/ml IL-3, 15.0… (More)
OBJECTIVE A complete process for mass generation of megakaryocytes from hematopoietic stem cells under serum-free conditions has great clinical potential for rapid platelet reconstruction in thrombocytopenia patients. We have previously reported on the generation of an optimized serum-free medium (serum-free hematopoietic stem cell medium) for ex vivo… (More)
Large-scale landslides often cause severe damage to lives and properties; therefore, their identification is essential in order to adopt proper mitigation measures. The objective of this study was to set up a methodological approach to help identify large-scale landslides using Lidar data, aerial photos and field investigation. The selected study areas were… (More)
