Layout is based on a hierarchical page partition, which provides explicit control over the aspect ratios and relative areas of the photos. We present an efficient method for finding a partition that produces a photo arrangement suitable for the shape of the page. Rather than relying on a stochastic search we employ a deterministic procedure that mimics the natural process of adding photos to the layout one by one.","PeriodicalId":184798,"journal":{"name":"2004 International Conference on Image Processing, 2004.

A nesting-structured framework is developed to combine a series of boosted classifiers into an efficient object detector. For omni-directional face detection, our method has achieved a rather high performance and the processing speed can reach 217 ms per 320/spl times/240 image. Experiment results on the CMU+MIT frontal and the CMU profile face test sets are reported to show its effectiveness.","PeriodicalId":184798,"journal":{"name":"2004 International Conference on Image Processing, 2004.

It delineates object boundaries by detecting a path with the minimum energy on the image. A worm algorithm based on deformable models is proposed to find the minimal path by using the dynamic programming technique. The proposed algorithm overcomes the shortcomings of traditional deformable models such as fastidious initialization and inefficiency on segmenting objects with complex shapes or topologies. After presenting the algorithm, its performance on various synthetic and medical images is shown. Experimental results indicate that the proposed algorithm is robust to noise and edge discontinuities.","PeriodicalId":184798,"journal":{"name":"2004 International Conference on Image Processing, 2004.

Isotropic rotationally invariant features are extracted from these subbands.

There are many approaches in the past that exploited either spatial or temporal correlations for generating prediction signals of an image in a block-by-block basis. Our method proposed in this paper exploits both spatial and temporal correlations at once to predict the pixels to be encoded. The prediction is achieved by using a template matching mechanism, with reference to previously reconstructed groups of pixels in the same frame or adjacent frames, to fill in the pixels of target regions of a frame. This process is conducted at both the encoder and decoder, and hence allows the decoder to produce the same predictor as the encoder does without any side information. Our coder uses the proposed prediction in addition to conventional motion compensation means. Simulation results show that our approach achieves up to 11.14% of improvements at the same PSNR over a codec which uses conventional block-based motion compensation.","PeriodicalId":184798,"journal":{"name":"2004 International Conference on Image Processing, 2004.

The above procedure is repeated until the final level is reached.

In particular, our scheme originates four descriptions from the spatially downsampled polyphase components of the original frames. Each description is compressed independently with the recent H264/AVC video coding standard, it is packetized and sent over an error prone network. In case of errors in one or more descriptions, appropriate concealing is applied at the receiver, before insertion of the corrected frames into the corresponding receiver frame buffers. We propose and compare different concealment solutions and a post processing stage to attenuate visual effects related to MD coding. We analyze the trade off between robustness to channel errors and coding efficiency, comparing the proposed technique with single description (SD) video coding with H264/AVC. Experimental results validate the effectiveness of the proposed scheme.","PeriodicalId":184798,"journal":{"name":"2004 International Conference on Image Processing, 2004.

It plays an important role in human computer interaction. This paper proposes a new approach to facial event recognition by combining active shape models (ASMs) and coupled hidden Markov models (CHMMs). Based on the assumption that a complex facial event can be decomposed into multiple coupled processes, ASMs are used to track global facial features and to decouple pattern attributes for upper and lower faces separately. These two interacting processes are modeled as a CHMM for training and recognition. Four basic facial events are investigated. Preliminary experiments yield consistent results that show the significant advantage of CHMMs over conventional HMMs for facial event mining in video.","PeriodicalId":184798,"journal":{"name":"2004 International Conference on Image Processing, 2004.

The points to be reconstructed are chosen from the contours of images, and a world-based formulation of the reconstruction problem and associated epipolar geometry is used. The result is a powerful mean of transparently integrating contributions from multiple images, and increased robustness to situations such as occlusions or apparent contours. Two steps for adding robustness are proposed: cross-checking, which validates a reconstructed point taken from an image by projecting it on a special subset of the remaining images; and merging, which fuses pairs of reconstructed points that are close in 3D space and that were initially chosen from different images. Results obtained with a synthetic scene (for ground truth comparison and error assessment), and two real scenes show the improved robustness achieved with the steps proposed.","PeriodicalId":184798,"journal":{"name":"2004 International Conference on Image Processing, 2004.
