In this paper, we propose a novel hybrid method for the segmentation and automatic counting of biological cell image. the method is based on techniques of morphology, thresholding and watershed. It performs well in low contrast image where gradient-based method may fail. Experimental results on practical cell images are shown in the paper with the emphasis on the comparisons between the novel hybrid...
In this paper, a novel approach for classifying algal images was presented, which is used in flow-cytometry-based real-time red tide monitoring system. Firstly, an ensemble of support vector machines (SVMs) was trained and the test samples were labeled by them based on the summation of negative probability (SNP). Secondly, those samples most likely mistakenly labeled were picked out and re-labeled...
In order to study the mechanism of the aqueous humor circulation and its relationship to the glaucoma macroscopically with engineering methods, a dynamistic model was presented, which can be used to simulate the situation of the primary angle closure glaucoma (PACG). The frame of the model was built based on the ophthalmic ally accepted feedback mechanism between the aqueous humor circulation and...
Some methods for registration of human eyes tissue images were described in this paper. Firstly, the algorithm of moment and principal axes was used to register the image sequence of eye's tissue slices in the rough. Then, a modified segmentation-counting registration algorithm was proposed to register the image sequence more accurately, which is not only as precision as maximization of mutual information...
In this paper an axisymmetrical, linear, finite element model of human crystalline lens and zonules is constructed to simulate the accommodation process of the lens, based on the published experimental data. Some detailed modeling procedure and data processing differ from previous studies. Our results show that the optical power increases when ciliary body moves away from the lens. The outcome of...
In order to study the mechanism of the aqueous humor circulation and its relationship to the glaucoma macroscopically with engineering methods, a dynamistic model was presented, which can be used to simulate the situation and the treatment of the primary open angle glaucoma (POAG). The frame of the model was built based on the ophthalmically accepted feedback mechanism between the aqueous humor circulation...
Hepatic vessel system is one of the most complex vessel systems in human body. For liver surgical planning, morphology and topology analysis of the hepatic vessel system is of our major interest. In this article, we present a new method to analyze the liver vessel system. Starting from the raw CT data set, vessel system is segmented. Based on that, then skeleton line of the vessel system is extracted...
