The algorithm of touching string segmentation is concerned in the work. We proposed an example based touching string segmentation algorithm. The supervised learning was used on the labelled examples and the Markov Random Field has been applied on. We used the belief propagation minimization method to select the candidate patches based on the compatibility(More)
An approach for improving the z-axis resolution of MRI using super resolution (SR) technology in the post processing step is proposed. The 2D multi-slice MRI is often anisotropic, the z-resolution lower than the in plane resolution. And the isotropic is necessary for certain diagnostic while the truly isotropic image is hardly obtained. In this case the(More)
In this paper, based on Novikov's explicit inversion formula for the attenuated Radon transform, we present a super resolution SPECT reconstruction algorithm with compensation for non-uniform attenuation. Unlike the former methods improving the medical image resolution via super resolution (SR) in the reconstructed image, the proposed method apply the SR(More)
An approach for improving the z-axis resolution of spiral CT using super resolution (SR) technology in the post processing step is proposed in this work. As the spiral CT has the ability to produce over-lapped slice images without over-lapped scanning, the sub-slice thickness shifts in z-axis require neither change in hardware nor any additional radiation(More)
In this paper, we proposed a novel approach to image completion for overlapping chromosomes. In our system, only given missing regions, the task can be performed automatically without human intervention. We address the problem of image completion for overlapping chromosomes in the context of a discrete global optimization problem. In order to reconstruct(More)
