SPEECH-DRIVEN MOUTH ANIMATION BASED ON SUPPORT VECTOR REGRESSION
"... Visual mouth information has been proved to be very helpful for understanding the speech contents. The synthesis of the corresponding face video directly from the speech signals is strongly demanded since it can significantly reduce the amount of video information for transmission. In this paper, we ..."
Abstract
- Add to MetaCart
, we present a novel statistical learning approach that learns the mappings from input voice signals to the corresponding mouth images. A deformable mouth template model is employed to parameterize the mouth shape corresponding to different transient speech signals followed by a radial basis function

MouthType: Text Entry by Hand and Mouth
- Proc. CHI 2004
, 2004
"... In this paper we describe a novel text entry method which uses coordinated motor action of hand and mouth. A vision based algorithm is used to gauge shape parameters of the cavity of the open mouth. These are mapped to a discrete set of input states which are combined with keypad input in a factoria ..."

The Sales Effect of Word of Mouth:
, 2006
"... Weekly sales of creative goods – like music records, movies or books – usually peak shortly after release and then decline quickly. In many cases, however, they follow a hump-shaped pattern where sales increase for some time. A popular explanation for this phenomenon is word of mouth among a populat ..."

A Study on the Effectiveness of Different Patch Size and Shape for Eyes and Mouth Detection
"... Abstract – Template matching is one of the simplest methods used for eyes and mouth detection. However, it can be modified and extended to become a powerful tool. Since the patch itself plays a significant role in optimizing detection performance, a study on the influence of patch size and shape is ..."

Accommodating for 3D Head Movement in Visual Lip Reading
- IN PROCEEDINGS OF IASTED INTERNATIONAL CONFERENCE ON SIGNAL AND IMAGE PROCESSING
, 2000
"... In automatic lipreading the speaker's head movement can aect the shape of the mouth appearing in the captured images independently of the true mouth shape. Such distortion of the mouth shape can lead to incorrect phoneme recognition. We have developed a system that robustly recognises visual ..."

AN EXTENDED MULTIRESOLUTION APPROACH TO MOUTH SPECIFIC AAM FITTING FOR SPEECH RECOGNITION
, 2011
"... Active Appearance Models (AAMs) are a widely used technique for face tracking. They work by minimising the difference between an unobserved image and a synthetically generated image created by a statistical model of the deformable object, e.g. a face. The Fixed Jacobian algorithm is the most widely ..."
Abstract
- Add to MetaCart
in which the area described by the AAM is reduced as the iterations progress. This allows the fitting technique to be more accurate as the fitting progresses. The new fitting structure is implemented with the Fixed Jacobian algorithm and then compared to a standard approach where the mouth shape
Mixed Fuzzy-system and Artificial Neural Network Approach to the Automated Recognition of Mouth Expressions.
- in: Eighth International Conference on Artificial Neural Networks
, 1998
"... One of the most important parts of the automatic recognition of facial expression is recognition of the mouth expression. This paper describes a new approach to this task. Contrary to the works already done in this fields, it is knowledge- rather than graphically- based. We use here a fuzzy-system i ..."

A Comparison of Active Shape Model and Scale Decomposition Based Features for Visual Speech Recognition
- In European Conference on Computer Vision
, 1998
"... Two quite different strategies for characterising mouth shapes for visual speech recognition (lipreading) are compared. The first strategy extracts the parameters required to fit an active shape model (ASM) to the outline of the lips. The second uses a feature derived from a one-dimensional multisca ..."

Frontal-View Face Detection and Facial Feature Extraction using Color, Shape and Symmetry Based Cost Functions
, 1998
"... We describe an algorithm for detecting human faces and facial features, such as the location of the eyes, nose, and mouth. First, a supervised pixel-based color classifier is employed to mark all pixels that are within a prespecified distance of "skin color," which is computed from a train ..."
