Description: 分割是在MRI analysis.We的基本问题之一，同时考虑了多种MR图像分割，其中，例如，可能是一个系列的问题经过一段时间的扫描相同的组织（的2D/3D）图像，图像的数量，或不同的切片图像的对称部分。 MR图像的多是分割份额常见的结构信息，因此他们可以协助彼此分割的程序。我们提出了一个贝叶斯共同分割算法在共享的信息整个图像是通过利用马尔可夫随机场前，和吉布斯采样后采样是有效的聘用。由于我们的共同拉动分割算法考虑到所有的图像信息的同时，它提供比个人更准确和坚实的结果分割，如支持从模拟和实际结果的例子。-Segmentation is one of the basic problems in MRI analysis.We consider the problem of simultaneously segmenting multiple MR images, which, for example, could be a series
of (2D/3D) images of the same tissue scanned over time,different slices of a volume image, or images of symmetric parts. The multiple MR images to be segmented share
common structure information and hence they are able to assist each other in the segmentation procedure. We propose a Bayesian co-segmentation algorithm where the shared information
across images is utilized via a Markov random field prior, and a Gibbs sampler is employed for efficient posterior sampling. Because our co-segmentation algorithm pulls
all the image information into consideration simultaneously,it provides more accurate and robust results than the individual
segmentation, as supported by results from both simulated and real examples.

Description: Gabor wavelet transform applied to feature extraction of ophthalmic images.
We investigate a new approach for measuring ocular
refractive errors (astigmatism, near-sightedness and shortsightedness)
from images of the human eye [1]. This
approach uses Support Vector Machines (SVMs) to
analyse data features extracted from images of the eye
acquired with a technique known as Hartmann-Shack [2]
and output measures for the eye´ s refractive errors. Prior to
analysis and feature extraction an image processing stage
takes place to identify and crop the region of interest
considering domain spatial and geometrical information.
Then a set of relevant image features are extracted using
wavelet and Garbor Transforms. These features are finally
fed into a SVM module for analysis that provides a
diagnosis of refractive errors present in the ocular globe
under investigation.

Description: 该论文是CVPR2009最佳论文，提出了一种新的图像去雾方法。-In this paper, we propose a simple but effective
image prior- dark channel prior to remove haze from a single
input image. The dark channel prior is a kind of statistics
of the haze-free outdoor images. It is based on a key
observation- most local patches in haze-free outdoor images
contain some pixels which have very low intensities in
at least one color channel. Using this prior with the haze
imaging model, we can directly estimate the thickness of the
haze and recover a high quality haze-free image. Results on
a variety of outdoor haze images demonstrate the power of
the proposed prior. Moreover, a high quality depth map can
also be obtained as a by-product of haze removal.

Description: the noise deteriorates the
interpolation performance in digital images, it is effective to
employ denoising prior to the interpolation. In this paper, we
propose a novel interpolation framework in which denoising
and image sharpening methods are embedded. In the
proposed framework, the image is first decomposed using the
bilateral filter into the detail and base layers which represent
the small and large scale features, respectively. The detail
layer is adaptively smoothed to suppress the noise before
interpolation and an edge-preserving interpolation method is
applied to both layers. Finally, the high resolution image is
obtained by combining the base and detail layers.
Experimental results show that the proposed algorithm
outperforms the conventional methods

Description: Single image haze removal has been a challenging
problem due to its ill-posed nature. In this paper, we propose a
simple but powerful color attenuation prior for haze removal from
a single input hazy image. By creating a linear model for modeling
the scene depth of the hazy image under this novel prior and
learning the parameters of the model with a supervised learning
method, the depth information can be well recovered.
