It is one of the important means to ensure safety transmission line and its equipment realize rapid identification accurate diagnosis visual defect fault points line. In this paper, an adaptive infrared image enhancement algorithm proposed based on research features various algorithms. The first filters remove random noise improve signal-to-noise ratio image; then, histogram analysis image, ada...

We investigate the relationship between the continuum enhancement and the hard X-ray (HXR) emission of a white-light flare on 2002 September 29. By reconstructing the RHESSI HXR images in the impulsive phase, we find two bright conjugate footpoints (FPs) on the two sides of the magnetic neutral line. Using the thick-target model and assuming a low-energy cutoff of 20 keV, the energy fluxes of n...

This paper describes a method for the enhancement of curvilinear structures such as vessels and bronchi in 3D medical images. A 3D line enhancement lter is developed with the aim of discriminating line structures from other structures and recovering line structures of various widths. The 3D line lter is based on a combination of the eigenvalues of the 3D Hessian matrix. Multi-scale integration ...

In this paper, we describe an approach of software product line testing which is based on formal specifications of the desired properties. In a software product line, common behaviours are maintained at subsequent levels of the product development. Commonalities among products arise from the reuse of parts of the software. It is unclear, however, in which way test cases for one product can be r...
