Real-time, adaptive measurement of corneal shapes
eye—the cornea, see Figure 1—is of tremendous importance to good vision. By the early 19th century, physicians recognized the cornea’s role in the refraction process. In the present day, several types of refractive surgery—such as corneal transplants and laser adjustment of the cornea—have become well established as techniques for improving a patient’s sight. To support these types of surgery, ...
متن کاملEstimating the Mode Shapes of a Bridge Using Short Time Transmissibility Measurement from a Passing Vehicle
This paper reports on the analysis of the signals sent by accelerometers fixed on the axles of a vehicle which passes over a bridge. The length of the bridge is divided into some parts and the transmissibility measurement is applied to the signals recorded by two following instrumented axles. As the transmissibility procedure is performed on the divided signals, the method is called Short Time ...
متن کاملReal-time damage detection of bridges using adaptive time-frequency analysis and ANN
Although traditional signal-based structural health monitoring algorithms have been successfully employed for small structures, their application for large and complex bridges has been challenging due to non-stationary signal characteristics with a high level of noise. In this paper, a promising damage detection algorithm is proposed by incorporation of adaptive signal processing and Artificial...
متن کاملReal-time Adaptive Gray Threshold Measurement in Extracting Traffic Parameters
In order to extract traffic parameters effectively in all day time, an adaptive gray threshold traffic parameters measurement (AGTTPM) system is built in this paper. In AGTTPM, a novel real-time adaptive gray threshold (RAGT) measurement method is presented to overcome the over sensitivity of vision based system to illumination changing. RAGT is a method which could highly enhance the detection...
متن کاملA Real Time Adaptive Multiresolution Adaptive Wiener Filter Based On Adaptive Neuro-Fuzzy Inference System And Fuzzy evaluation
In this paper, a real-time denoising filter based on modelling of stable hybrid models is presented. Thehybrid models are composed of the shearlet filter and the adaptive Wiener filter in different forms.The optimization of various models is accomplished by the genetic algorithm. Next, regarding thesignificant relationship between Optimal models and input images, changing the structure of Optim...
