In contrast to the extensively researched modeling of plant architecture, the modeling of plant organs largely remains an open problem. In this paper, we propose a method for modeling lobed leaves. This method extends the concept of sweeps to branched skeletons. The input of the model is a 2D leaf silhouette, which can be defined interactively or derived(More)
This contest involved the running and evaluation of computer vision and pattern recognition techniques on different data sets with known groundtruth. The contest included three areas; binary shape recognition, symbol recognition and image $ow estimation. A package was made available for each area. Each package contained either real images with manual(More)
We studied the effect of xenogenic neonatal cardiomyocytes on enzymatic processes in rat myocardium under conditions of epinephrine-induced damage. It was found that transplantation of the cell preparation restricts the zone of suppressed enzyme activity in the myocardium and promotes its recovery. Less pronounced metabolic disturbances corresponded to less(More)
Template matching is rarely used for symbol recognition in practice because of the variation in scale, orientation, and line thickness and position found in actual images. An answer to this is to use an adaptable template, one that can be scaled and rotated easily. Here the use of such a template, based on vector representation of symbols, is explored.(More)
The effects of transplantation of xenogenic neonatal heart cells on energy processes were studied in rat myocardium during the early period of epinephrine injury. Transplantation promoted a less pronounced ATP hydrolys to adenosine monophosphate and inorganic phosphate, a higher level of creatine phosphate, pyruvate, lactate, retention and activation of(More)
