A method for computing the width of blur is presented based on the gradient image of blurring image.

提出了一种基于模糊图像的梯度图像计算模糊宽度的方法。

And the restoration equation with specific constraint can restore space-variant blurring image effectively.

The features achieve partial invariance to local variations, such as affine or 3D projections, by blurring image gradient locations.

They concluded that the black drop results from blurring of the image (whether from Earth's atmosphere, or inevitable imperfections of the telescope) combined with the way that the disc of the sun fades in brightness towards its rim.

Dr Massey and his colleagues were able to map the matter (both dark and visible) in the bit of the firmament covered by the Cosmic Evolution Survey by looking for characteristic distortions in the shape of distant galaxies that only Hubble, which is beyond the image-blurring effects of the atmosphere, can see.

Combined with the COOLPIX P7700's powerful CMOS sensor, this bright, large-aperture NIKKOR lens provides reduced noise, beautiful background blurring, fast performance and high image quality whether shooting stills or Full HD video.
