TiO2 nanoparticles with different quantity Ni doping were synthesized by hydrothermal process. XRD, SEM, BET were used to characterize the crystal phase and micro-topography of samples. Besides, combining with mathematic morphology and fractal theory, the data of characterition were analyzed, the distribution and evolution of the microstructure of samples were discussed as well in this paper. The...
Most image inpainting techniques require a human to identify manually the portion to be inpainted. We propose a new detection algorithm which can automatically detect defect portions in an image, including arbitrary scratches by color ink. The proposed algorithm is based on the characteristics of uniform gray of scratches and structural information of scratches. In this algorithm, we apply top-hat...
Target discrimination is the key step of automatic target detection in synthetic aperture radar (SAR) images. Aiming at the issue of aircraft discrimination in high resolution SAR images, a novel discrimination method is proposed with using texture features. First of all the method of gray level co-occurrence matrix is used to generate eight discrimination texture features: mean, variance, deficit...
