医学图像配准,医学图像2D_3D配准,基于vc++开发。(The registration of pre-operative volumetric datasets to
intra-operative two-dimensional images provides an im-
provedway of verifying patient positionandmedical instru-
ment location. In applications from orthopedics to neuro-
surgery, it has a great value in maintaining up-to-date in-
formation about changes due to intervention. We propose a
mutual information-based registration algorithm which es-
tablishes the proper alignment via a stochastic gradient as-
centstrategy. Ourmaincontributionliesinestimatingprob-
ability density measures of image intensities with a sparse
histogrammingmethodwhichcouldlead to potentialspeed-
up over existing registration procedures and deriving the
gradient estimates required by the maximization procedure.
Experimental results are presented on fluoroscopy and CT
datasets of a real skull, and on a CT-derived dataset of a
real skull, a plastic skull and a plastic lumbar spine seg-
ment.)

LSB替换隐写
说明: LSB(英文 least significant bit)即最低有效位。LSB加密是信息隐藏中最基本的方法。由于人们识别声音或图片的能力有限,因此我们稍微改动信息的某一位是不会影响我们识别声音或图片的。(LSB replace steganography)

混合高斯模型使用K(基本为3到5个) 个高斯模型来表征图像中各个像素点的特征,在新一帧图像获得后更新混合高斯模型,用当前图像中的每个像素点与混合高斯模型匹配,如果成功则判定该点为背景点, 否则为前景点。通观整个高斯模型,他主要是有方差和均值两个参数决定,,对均值和方差的学习,采取不同的学习机制,将直接影响到模型的稳定性、精确性和收敛性。由于我们是对运动目标的背景提取建模,因此需要对高斯模型中方差和均值两个参数实时更新。为提高模型的学习能力,改进方法对均值和方差的更新采用不同的学习率 为提高在繁忙的场景下,大而慢的运动目标的检测效果,引入权值均值的概念,建立背景图像并实时更新,然后结合权值、权值均值和背景图像对像素点进行前景和背景的分类。(Gaussian mixture model using K (essentially 3-5) Gaussian model to characterize the features of each pixel in the image, in the image of the new frame for updated Gaussian mixture model, with each pixel in the image with a Gaussian mixture current model matching, if successful, determined that the point of the background points, otherwise the former attraction. Throughout the entire Gaussian model, he mainly has two parameters determine the variance and the mean, the mean and variance of the study, to take a different learning mechanism, will directly affect the stability, accuracy and convergence model. Since we are moving object extraction of the background modeling, so the need for the Gaussian model variance and mean two parameters real-time updates. In order to improve the learning ability of the model, an improved method for updating the mean and variance of different learning rates to improve in the busy scene, large and slow moving object detection results, the introduction of)
