Superpixel algorithm aims to semantically group neighboring pixels into a coherent region. It could significantly boost the performance of the subsequent vision processing task such as image segmentation. Recently, the work simple linear iterative clustering (SLIC) [1] has drawn huge attention for its state-of-the-art segmentation performance and high computational efficiency. However, the performance...
Quartz wafer inevitably produces various physical defects in the production process. This paper focuses on the quartz wafer dirt defects, and proposes a way for image processing on the quartz wafer by using of computer vision library OpenCV. The proposed method is to find contours of the processed images to judge whether there is dirt or not. Experiments show that this method can well detect the dirt...
The stochastic packet dropouts often occur in the networked control systems (NCSs), which can degrade performance or stability of the systems. An optimal estimation of the dropped data during the transmissions is often inevitable. This paper has proposed a new compensation method for NCSs with packet dropouts using measurement predictor, the estimated measurement values for the lost information are...
Since many extremely susceptible components with low-voltage operation or high sensitivity may be affected from EMI noise and thus degrade their performance, the EMI phenomena from IC becomes an issue for semiconductor industry. In this paper, we have designed a TEM Cell and magnetic field probe with high sensitivity and spatial resolution, in accordance with the IC-EMI measurement standard IEC 61967-2...
The simulation of remote-sensing sensor is a useful tool for a variety of tasks such as the design of systems, the understanding of the image formation process, and the development and validation of data processing algorithms. Based on the analysis of the principle of SMIFTS(Spatially Modulated Imaging Fourier Transform Spectrometer), a model for simulating the image progress of SMIFTS had been developed...
A new UKF based for radar and infrared sensor registration method is provided. A so-called "hybrid states" concept is introduced to describe target's state, which consists of the target's range, bearing and elevation and its velocity in the Cartesian coordinate system. The dynamic function and the measurement function are deduced in hybrid states. Simulation results show that the proposed...
