In order to quickly operate large quantities of cells and obtain optimized operation sequence, it is ideal to get location information of overall cells to be operated. Therefore this paper collects low-resolution microscopic images in which we can observe a large sum of cells. To obtain their accurate locations, this paper puts forward Improved Circle Similarity Algorithm for solving the problem of...
This paper presents the application of finite element method in analysis of the electromagnetic field within real head model exposed to a time varying magnetic field produced by the circuit-driving loop. To analyze the electromagnetic field under Transcranial Magnetic Stimulation precisely and display the stimulating effect of the loops in different geometrical forms, a 3-D real head model reconstructed...
For observing the changing process of the micro objects in biomedicine area, micro image sequences need to be developed by extending the three-dimensional microscopic images in the temporal domain. Due to the slow changing rate of the micro object, micro image sequences have a large number of temporal redundancies. In order to improve the tracking efficiency, a novel scale adjustable frame mapping...
We present a registration method in which we use the penalized maximum likelihood (PML) function, as a new measure, defined by the transition probabilities between the image intensities of corresponding pixels in both images. The value of measure is computed from the joint histogram obtained from the intensities of all pixel pairs in the overlapping area of two images and if two images are geometrically...
In this paper, we use the mean shift procedure to determine the number of components in a mixture model and to detect their modes of each mixture component. Next, we have adopted the Gaussian mixture model to represent the probability distribution of feature vectors. A deterministic annealing expectation maximization algorithm is used to estimate the parameters of the GMM. The experimental results...
The tongue diagnosis is an important diagnostic method in traditional chinese medicine (TCM). In this paper, we present a novel computerized tongue inspection method based on support vector machine (SVM). First, two kinds of quantitative features, chromatic and textural measures, are extracted from tongue images by using popular image processing techniques. Then, support vector machine and Bayesian...
In solving intra-voxel fiber crossing problem in white matter fiber tracking, the classification of crossing and non-crossing regions seems essential and challenging. Although high Cp value is a usable indicator of intra-voxel orientational heterogeneity, only using this metric is not accurate enough to decide exactly whether fiber crossing occurs as the lack of an exact and recognized threshold....
The directional diffusion information obtained by diffusion tensor magnetic resonance imaging (DT-MRI) can be used to noninvasively visualize white matter fibers in human brain. And it is the unique way to reconstruct those fibers in vivo. However, there are some obstacles for the reconstruction process, e.g., partial volume effect caused by low spatial resolution negatively affects the DT-MRI results,...
