To effectively estimate camera motion parameters (zoom, pan, tilt, swing, and focal length) from image sequences, we propose a new linear motion parameter equation and use the Kalman filtering method to solve it. Unlike the existing linear techniques, the proposed linear method accurately estimates the large rotation angles and the focal length. Experimental results show that the proposed method outperforms the conventional linear methods, especially for a large rotation angle.","PeriodicalId":92344,"journal":{"name":"Computer analysis of images and patterns : proceedings of the ...

The proposed technique is based on a matching block integration using a reliability metric of motion vectors. First, the reliability metric is computed for all the matching blocks in the target image and then, based on this value and its dependency on the direction, four neighboring matching blocks are checked whether they should be integrated or not. Finally, motion vectors are estimated for the integrated matching blocks by the block matching technique. Since the block integration is performed only for flat matching blocks or those with a simple edge, the coherence is improved while the performance of motion compensation is kept as far as possible. The examples given show the effectiveness of the proposed approach.","PeriodicalId":92344,"journal":{"name":"Computer analysis of images and patterns : proceedings of the ...

For binary images, the flat zones are the foreground and background grains (connected components) of the image. The flat zones constitute a partition of the underlying space. A connected operator is an operator that makes this partition coarser. A grain operator is a connected operator that is uniquely specified by two grain criteria, one for the foreground and one for the background components. This paper provides a discussion of connected operators and grain operators with an emphasis on connected filters, all in the context of binary images.","PeriodicalId":92344,"journal":{"name":"Computer analysis of images and patterns : proceedings of the ...

The multichannel representation of the subband signal is combined with the statistical model of the input signal to derive the multirate state-space model for a filter bank system with additive noise. Thus the signal reconstruction problem in the subband system can be formulated as the process of optimal state estimation in the equivalent multirate state-space model. With the input signal embedded in the state vector, the multirate Kalman filtering provides the minimum-variance reconstruction of the input signal. Using the powerful Kronecker product notation, the results and derivations can then be extended to the 2-D cases. Incorporated with the vector dynamical model, the 2-D multirate state-space model for 2-D Kalman filtering is developed. Computer simulation with the proposed 2-D multirate Kalman filter gives favorable results.","PeriodicalId":92344,"journal":{"name":"Computer analysis of images and patterns : proceedings of the ...

This approach is performed entirely automatically. We utilize two views of a person's face, and the fiducial points defined on a generic facial model, to modify the generic model into a 3D individual model of a face. To deform the generated individual facial model for tracking the expression of a face over time, a new method named the layered force spreading method (LFSM) is proposed which makes the animation of facial expressions looks more natural. The feasibility of our approach is demonstrated using a real facial image.","PeriodicalId":92344,"journal":{"name":"Computer analysis of images and patterns : proceedings of the ...
