We present MikeTalk, a text-to-audiovisual speech synthesizer which converts input text into an audiovisual speech stream. MikeTalk is built using visemes, which are a small set of images spanning a large range of mouth shapes. The visemes are acquired from a recorded visual corpus of a human subject which is specifically designed to elicit one instantiation of each viseme. Using optical flow m...

Linear geometry interpolation (or morphing) is useful to display key frame animations. This work briefly explains prerequisites and useful properties for morphing and describes a prototype implementation within the geometry framework of OpenSG.

Image morphing techniques can create a smooth transition between two images. However, one of the main weakness of the image morphing technique is that intermediate images in the transition often have physically incorrect shading such as highlights and shadows. Moreover, we cannot alter viewing and lighting conditions when creating the intermediate images. That is because those images are obtain...

Face identification is becoming a well-accepted technology for access control applications, both in the real or virtual world. Systems based on this must deal with persistent challenges of classification algorithms and impersonation attacks performed by people who do not want to be identified. Morphing often selected conduct such since it allows modification features an original subject’s image...

This paper presents high-level strategies for controlling emotional speech morphing algorithms. Emotion morphing is realized by representing the acoustic features in their timefrequency plan that is warped and modified to generate natural morphed emotional speech. These acoustic features are desirable to be decomposed into multidimensional space and to be orthogonal. After matching these acoust...

A new type of ensemble filter is proposed, which combines an ensemble Kalman filter (EnKF) with the ideas of morphing and registration from image processing. This results in filters suitable for nonlinear problems whose solutions exhibit moving coherent features, such as thin interfaces in wildfire modeling. The ensemble members are represented as the composition of one common state with a spat...

Image morphing has been the subject of much attention in recent years. It has proven to be a powerful visual effects tool in film and television, depicting the fluid transformation of one digital image into another. This paper reviews the growth of this field and describes recent advances in image morphing in terms of three areas: feature specification, warp generation methods, and transition c...

The performance of many mechanical systems is directly related to the geometric shapes of their components, such as aircraft wings and antenna reflectors. While the shapes of these components are mostly fixed, incorporating shape morphing into these systems can increase the flexibility and enhance the performance. A synthesis approach for shape morphing compliant mechanism is presented in this ...

We present a method for naturally and continuously morphing two simple planar polygons with corresponding vertices in a manner that guarantees that the intermediate polygons are also simple. This contrasts with all existing polygon morphing schemes who cannot guarantee the non-self-intersection property on a global scale, due to the heuristics they employ. Our method achieves this property by r...

Traditional automatic face morphing techniques tend to generate blurry intermediate frames when the two input faces differ significantly. We propose a new face morphing approach that deals explicitly with large pose and expression variations. We recover the 3D face geometry of the input images using a projection on a prelearned 3D face subspace. The geometry is interpolated by factoring the exp...
