Blind image quality assessment refers to the problem of evaluating the visual quality of an image without any reference. In this paper, we present a no-reference blur metric for images and video using information contained in the image itself. We look at the sharpness of the sharpest edges in the blurred image, which contains information about the blurring,(More)
There is no targeted strategy for different noises for the Magnetic Resonance Sounding detecting underground water at present, in order to improve the filtering effects, save the measure time, and then ensure the accuracy of inversion result, the targeted strategy are provided in this paper. The signal measured from Magnetic Resonance Sounding (MRS)(More)
The adaptive filter is an effective method to dealing with such kind of non-steady random signal of the heart rate. The algorithm of clipped- error LMS algorithm with variable step size of segmenting type was proposed. We adopted auto-regression predict filter estimating the noise of heart rate signals through Doppler ultrasound sensor. We used it as the(More)
