Cholinergic inputs from the medial septum are projected to pyramidal neurons in the hippocampal CA1 region and release acetylcholine (ACh) from their terminals. The cholinergic inputs are considered to be integrated with sensory inputs and to play a crucial role in learning and memory. Meanwhile, it has been reported that the relative timing between pre-(More)
Processes such as modeling, rendering and simulating hair are essential for creating virtual humans in various CG applications. CG hair motion simulations are commonly constructed using a physics-based model and have been extensively researched. While physics-based approaches have achieved effective and sophisticated hair motion, data-driven approaches for(More)
In-between creation in traditional cel animation based on the hand-drawn key-frames is a fundamental element for the actual production and plays a symbolic role in an artistic interpretation of the scene. To create impressive in-betweens, however, animators are required to be skilled for hair animation creation. In the traditional cel animation, hair(More)
The hair movement in cel character animation is sometimes inconsistent. The representation of hair, therefore, is a specialized work in cel animation. It is difficult to achieve in computer graphics, since cel animation may not be consistent with all the hair’s attributes from all camera positions. In fact, what animators create by solving physics equations(More)
We construct novel car designing tool, which helps car designers to design cars efficiently and stimulates their artistic sensibilities. Cars are synthesized by analyzing various existing car body shapes and extracting meaningful attributes that represent the features of these shapes. First, a database of existing cars is created. We analyze all shapes(More)
For improving the efficiency of 2D animation production, this paper presents a method to create in-between frames based on hand-drawn key-frames. The outlines of characters or objects on two key-frames are used as inputs. First, a skeleton linkage of the target object is automatically constructed by rasterizing each of input key-frames and then applying a(More)
