The special conditions during in vitro culture result in the formation of plantlets of abnormal morphology, anatomy and physiology. After ex vitro transfer, these plantlets might easily be impaired by sudden changes in environmental conditions, and so need a period of acclimatization to correct the abnormalities. This review is focused upon contemporary(More)
Image analysis was used in studying stomatal morphology during acclimatization of tobacco plantlets to ex vitro conditions, 45 d after transfer leaf area was 15 times, and total number of stomata per leaf four times increased. During acclimatization stomatal density was decreased considerably on both leaf sides, and was compensated by an increase in(More)
Nicotiana tabacum L. plantlets were cultured in vitro photoautotrophically (0% sucrose) and photomixotrophically (3% or 5% sucrose) at two irradiances (80 or 380 mumol m-2 s-1) with the aim of investigating the effect of these culture conditions on photosynthetic parameters and on protective systems against excess excitation energy. In plantlets grown(More)
We present a novel physics-based approach to facial animation. Contrary to commonly used generative methods, our solution computes facial expressions by minimizing a set of non-linear potential energies that model the physical interaction of passive flesh, active muscles, and rigid bone structures. By integrating collision and contact handling into the(More)
I would like to thank my supervisor, Mgr. Petr Kmoch, for his support, availability and constructive suggestions. He has guided me in the correct directions during my master thesis and helped me with his feedbacks. I would also like to express my gratitude to my family and my girlfriend for their continuous support and patience. I declare that I carried out(More)
We present a method to create personalized anatomical models ready for physics-based animation, using only a set of 3D surface scans. We start by building a template anatomical model of an average male which supports deformations due to both 1) subject-specific variations: shapes and sizes of bones, muscles, and adipose tissues and 2) skeletal poses. Next,(More)
Under-actuated 6/3-DOF haptic devices are mostly used for simple 3-DOF point-based haptic interaction because of missing torque feedback. In this work, we present a system involving sensory substitution and pseudo-haptic feedback that effectively simulate torque feedback using visuo-tactile cues. The proposed system was implemented into a 6-DOF haptic(More)
