Graph-cut optimization has been successfully applied in many image segmentation tasks. Within this framework color information has been extensively used as a perceptual property of objects to segment the foreground object from background. There are different representations of color in digital images, each with special characteristics. Previous work on segmentation lacks a systematic study of which...
Segmentation of Synthetic Aperture Radar (SAR) images is often only understood as the partitioning of the image into rather small regions which are homogeneous with respect to scattering processes. This paper proposes an adaption of the graph-cut image segmentation framework to the unique characteristics of polarimetric SAR images by using a Wishart-distribution based distance measure for local segmentation...
The inconsistent diagnostic information often occurs in fault diagnosis of complex equipments. In order to improve the diagnosis precision, an integrated fault diagnosis method is proposed based on variable precision rough set (VPRS) and Naive Bayesian network classifier (NBNC). Firstly, according to the relative discernibility of the original fault diagnosis decision table, the β in VPRS is self-determined...
Based on Atmel Corporation's microcontroller ATmega16L and ultrasonic sensor TCT40-16F, designs an ultrasonic measurement and alarm system with high precision. Using the method of MJ echo capture, the system can realize measuring the distance well and truly, and can send the real time distance data to the LCD screen of system. Once the distance was less than the setting value, the system would alarm...
Due to their ability to model sequential data without making unnecessary independence assumptions, conditional random fields (CRFs) have become an increasingly popular discriminative model for human activity recognition. However, how to represent signal sensor data to achieve the best classification performance within a CRF model is not obvious. This paper presents a framework for extracting motif...
In terms of double-controller design technology and relay feedback identification method an autotuning IMC structure with two degree of freedom (TDF-IMC) is proposed in this paper. The model parameters of the controlled process are identified via a modified relay feedback identification method. The setpoint tracking IMC controller and disturbance attenuation IMC controller are designed, respectively,...
