The determination of the three-dimensional (3D) structure of biological macromolecules at different configurations can be very important for understanding biological processes at the molecular level. The detection of individual particles from electron microscopy (EM) micrographs turns into a major labor-intensive bottleneck, when the number of particles(More)
Non-photorealistic rendering (NPR) is a class of techniques defined by what they do not aim, the realistic rendering of artificial scenes. NPR techniques, on the other hand, aim to reproduce artistic techniques renderings, trying to express feelings and moods on the rendered scenes.

Stylized rendering is the process of generating images or videos that can have the visual appeal of pieces of art, expressing the visual and emotional characteristics of artistic styles. A major problem in stylizing videos is the absence of temporal coherence, something that results in flickering of the structural drawing elements (such as brush strokes or(More)
Video segmentation can be defined as the process of partitioning video into spatio-temporal objects that are homogeneous in some feature space, with the choice of features being very important to the success of the segmentation process. Fuzzy segmentation is a semi-automatic region-growing segmentation algorithm that assigns to each element in an image a(More)
