coefficients for embedding the watermark, three different aspects, imperceptibility, security, and bit rate increase, have<br />

been considered. These performance factors are adjusted by defining three priority matrices. In addition, a content based<br />

key is proposed in order to overcome the collusion attack. The flexibility of our method to provide desired characteristic<br />

can be expressed as another advantage.<br />

Lip Segmentation using Level Set Method: Fusing Landmark Edge Distance and Image Information<br />

Banimahd, Seyed Reza, Sahand Univ. of Tech.<br />

Lip segmentation is an essential step in audio-visual processing systems. In this paper, we incorporate the color and edge<br />

information in level set formulation, for extraction of lip contour. We build two initiative auxiliary images by mixing of<br />

different color spaces, to extract the landmark edges for upper and lower part of lip. The performance of this approach on<br />

VidTIMIT databases is tasted and accuracy of 91.2% is reached.<br />

This paper proposes an adaptive color independent components based SIFT descriptor (termed CIC-SIFT) for image classification.<br />

Our motivation is to seek an adaptive and efficient color space for color SIFT feature extraction. Our work has<br />

two key contributions. First, based on independent component analysis (ICA), an adaptive and efficient color space is<br />

proposed for color image representation. Second, in this ICA-based color space, a discriminative CIC-SIFT descriptor is<br />

calculated for image classification. The experiment results indicate that (1) contrast between objects and background can<br />

be enhanced on the ICA-based color space and (2) the CIC-SIFT descriptor outperforms other conventional color SIFT<br />

descriptors on image classification.<br />

Joint Registration and Segmentation of Histological Volume Data by Diffusion-Based Label Adaption<br />

Bollenbeck, Felix, Fraunhofer Inst. for Factory Operation and Automation<br />

Three-dimensional serial section imaging delivers high spatial resolution and histological detail, which facilitates analysis<br />

of differentiation and development by exact labelling of tissues and cells, unknown to other 3-D imaging modalities. We<br />

propose an algorithm for interleaved reconstruction and segmentation of tissues in serial section volumes by diffusionbased<br />

registration and adaption of two-dimensional reference labellings. Iterative refinement of the global image congruence<br />

and local deformation of labellings delivers an efficient algorithm for processing of large volume data-sets. The<br />

benefits of the approach are shown by means of reconstruction and segmentation of giga-voxel serial section volumes of<br />

plant specimen.<br />

Craniofacial disorders commonly result in various head shape dysmorphologies. The goal of this work is to quantify the<br />

various 3D shape variations that manifest in the different facial abnormalities in individuals with a craniofacial disorder<br />
