Multi-photon fluorescence microscopy (MFM) captures high-resolution anatomical and functional fluorescence image sequences and can be used for the intact brain imaging of small animals. Recently, it has been extended from imaging anesthetized and head-stabilized animals to awake and head-restrained ones for in vivo neurological study. In these applications,(More)
Object tracking is the key issue for autonomous mobile robot navigation. In this paper, a method of mobile robot object tracking is put forward based on feedback of monocular-vision. This method implements object tracking through identifying the special sign. And this method can also simulate the spacecraft RVD. Experiments show: the method is effective for(More)

Aiming at the problem of obstacles avoidance from a single camera mounted on a robot in an unstructured indoor environment, the paper proposed an algorithm based on template matching. Firstly, the scenepsilas free space and obstructed space can be obtained by means of template matching. Secondly, we can get the robotpsilas running orientation and speed from(More)
Segmentation of neural stem cells is the preliminary step to treat and cure several brain neural diseases. There exist a number of methods to accomplish this task. However, all of these methods suffer from some problems, such as high intensity variation sensitivity, human interaction and high computational complexity. In this paper we proposed a novel(More)
An original approach to roto-translation estimation for images related by rotation and translation is investigated. The algorithm is operated in the frequency domain, where phase correlation is used for translation estimation and magnitude correlation is employed to rotation estimation. In the rotation estimation part, spectra of refereeing images are(More)
Purpose – The purpose of this paper is to describe how, in order to fulfill the specific missions under some special environments without people participating, a multi-robot object tracking and docking systems are designed based on networked control frames. Design/methodology/approach – In the process of target recognition and tracking, the tracking robot(More)
To solve the problem of edge blurring and inaccuracy in image interpolation, we propose an edge-preserving interpolation method based on in-pixel grayscale modeling and adaptive weighted linear interpolation. First, edges are determined by integrating the grayscale changes of the image window and calculating the maximal eigenvalue of the result matrix. Then(More)
