Animation of a Blooming Flower Using a Family of Complex Functions M ζ , α ( z ) = exp ( − α ζ + z ζ − z )
Models and Techniques in Computer Animation, 1993Co-Authors: Sung Yong ShinAbstract:Recently, Kim et. al.(1992) addressed the properties of a family of complex functions M ζ, α(z) = exp\(( - \alpha \frac{{\zeta + z}}{{\zeta - z}})\) where α > 0 and |ζ| = 1. When Newton’s method is applied to solve M ζ,α (z) − 1 = 0, the basins of attraction for its roots show flower-like self-similar structures which vary according to the value of α. From an artistic point of view, we explore those self-similar strucures for an Animated Sequence of flower blooming by extending M ζ,α (z) for α ≠ 0.

Effects of visual grouping strategies of computer-Animated presentations on selective attention in science
Educational Technology Research and Development, 1991Co-Authors: Lloyd P. RieberAbstract:The effects of visual grouping strategies involving Animated and static graphic presentations on selective attention were studied. Also studied was the ability of students to learn a scientific rule presented incidentally in an Animated Sequence. A total of 39 fourth-graders participated in an introductory lesson on Newton's laws of motion. Two levels of Visual Presentation (Static Graphic, Animated Graphic) were crossed with two levels of Visual Grouping (Grouped, Ungrouped). A within-subjects factor consisted of two levels of Learning Intent (Intentional, Incidental). Results showed that students given Animated presentations of lesson content outperformed students receiving static presentations, but only when the Animated lesson frames were presented in groups, or “chunks,” of textual and visual Sequences. Results also showed that students were able to successfully extract information pertaining to an application of Newton's second law incidentally presented in Animated Sequences. These latter results replicate earlier findings.

IMAGE MORPHING USING HYBRID MESH-KLT ALGORITHM
International Journal of Advanced Research in Computer Science, 2018Co-Authors: Deepalakshmi RAbstract:Image morphing provides visual effects in TV and film. Image Morphing springs from the word Metamorphosis. Transition of source image to target is termed as Morphing. This is frequently used in an animation technique that morphs the initial image into the final image. The morphing strategy has 2 stages: Starting point it warps 2 pictures to possess similar form and in later step it cross dissolves ensuing pictures. This paper uses hybrid mesh-field warping methodology to make a structure of image morphing of facial animation with low simplicity. An attempt is made in morphing using hybrid mesh-KLT algorithmic rule combined with Cross Dissolving technique. During morphing method, the program can output N range of pictures. These pictures are used consecutive to develop a brief Animated Sequence.

Symposium on Computational Geometry - Adaptive mesh generation for real-time terrain modeling
Proceedings of the twentieth annual symposium on Computational geometry - SCG '04, 2004Co-Authors: M. L. GavrilovaAbstract:In this simulation we demonstrate how real-time multi-resolution approaches based on underlying geometries are used in terrain visualization. The Animated Sequence demonstrates applications based on the modified ROAM scheme and the adaptive loop subdivision methods.

An Implementation of Image Morphing Through Mesh Morphing Algorithm
2012Co-Authors: Urvashi Bhushan, G. P. Saroha, Disha TiwariAbstract:The term "morphing" is used to describe the combination of generalized image warping with a cross-dissolve between image elements. The term is derived from "image metamorphosis". Morphing is an image processing technique typically used as an animation tool for the metamorphosis from one image to another. The idea is to specify a warp that distorts the first image into the second. Its inverse will distort the second image into the first. As the metamorphosis proceeds, the first image is gradually distorted and is faded out, while the second image starts out totally distorted toward the first and is faded in. Thus, the early images in the Sequence are much like the first source image. The middle image of the Sequence is the average of the first source image distorted halfway toward the second one and the second source image distorted halfway back toward the first one. The last images in the Sequence are similar to the second source image. The middle image is key if it looks good then probably the entire Animated Sequence will look good. For morph between faces, the middle image often looks strikingly life-like, like a real person, but clearly it is neither the person in the first nor second source images.The morph process consists of warping two images so that they have the same "shape", and then cross dissolving the resulting images. Cross-dissolving is the major problem as how to warp an image. In this paper the image morphing is implemented using mesh warping algorithm and the software is implemented in java using netbeans and images are used from the internet and from digital camera. The program will output N images that perform the morphing. These images can then be edited together into a short Animated Sequence. Keywords— Morphing, Distorted, Faded, Cross-Dissolve, Warping.
