For static gestures image classification problems, this paper proposed a kind of image recognition method based on the unsupervised feature learning, mainly using the sparse auto-encoding neural network model to extract image edge feature which is belong to unsupervised feature learning, then let the edge feature as the input of the classifier, finally sort and identify the gesture image which having...
We have developed a cubic eggshell made of a cubic polycarbonate frame and 6 PDMS membranes. Development of embryo circulatory system was observed on the transparent side membrane. We hypothesized that blood vessels, which adhered on the side membrane for oxygen absorption, respond specifically to different oxygenated environment. To test this hypothesis, we designed patterned surfaces with selective...
We propose a novel system for the observation of living cell exposed to cyclic stretch under dynamic conditions. The developed system is mainly composed of a laptop PC, a stretching unit with three motorized stages, and a microscope with a CCD camera. The design of the cell tracking system is based on the deformation characteristics of the elastic chamber and its performance was confirmed through...
We have proposed a novel cubic (artificial) eggshell containing a chick embryo. Since the posture of the eggshell can be changed freely and the manipulation of the chick embryo is possible, the developed cubic eggshell with a chick embryo is a good model for microsurgery training. In this study, we further demonstrate the promising use of the eggshell. First, the viability of the chick embryo in the...
We propose a novel biomedical platform of a cubic (artificial) eggshell containing a chick embryo. The use of this proposed platform can eliminate the use of large animals as experimental models, making it more ethically accepted. It also has the advantages of low cost and a small size. The specific design and fabrication method of the cubic eggshell uses polydimethylsiloxane (PDMS) and polycarbonate,...
Global leaf area index (LAI) products such as MODIS LAI product et al. have relatively low spatial resolution (250m–7km) and can not meet the needs of high spatial resolution remote sensing applications. Therefore, it is necessary to explore the feasibility of the algorithm based on physical model for LAI retrieval using high spatial resolution remote sensing imagery. This study utilized the algorithm...
