Digital image processing is widely used in the crack detection and location. In order to guide staff maintenance equipment more effectively and timely, the image detection system based on crack which has been put forward. On the basis of LabVIEW platform, Crack image in this system is acquired that using two industrial cameras, and then used the SIFT feature matching, RANSAC and image fusion to stitch...
A new density- and grid-based clustering algorithm is proposed to identifying free shape clusters. The proposed algorithm is a non-parametric method, which does not require user specifying parameters for clustering. The algorithm divides each dimension of the data space into certain intervals to form a grid structure. The valley seeking procedure is employed to find the cluster centers where the data...
The Detection and analysis of neural spike activity is a prerequisite for studying many types of brain functions. In this paper, we introduce an open source toolbox built in MATLAB called SPKtool for spike analysis. SPKtool functions support common requirement for analysis of neural spikes, including spike detection, feature extraction, manual and semi-automatic clustering methods and graphical tools...
