Abstract:
In the era of big data, we are exposed to more and more digital images, and
inevitably, various degrees of deterioration and distortion occur in the
process of image formation, transmission, storage, recording and display.
People's lives are becoming more and more abundant, the application of cameras
is becoming more and more common, and motion blur is also a problem that is
easy to occur in the imaging process. As images become more closely related to
people's lives, the demand for high quality images is increasing. In this
paper, we first introduce two methods for the formation of motion blur images,
namely the heavy-tailed distribution method and the Fourier transform method.
The heavy-tailed distribution method can determine whether the image is a
blurred image by using the obtained graphic, and the Fourier transform method
is mainly used to determine which kind of blurred image the fuzzy image is
specifically. Through the analysis of the causes of image formation, we have
stepwise optimization of our images from two different angles, namely,
deblurring and denoising. We first assume that the noise conditions are known,
and use the modeling method to simulate the fuzzy trajectory of the motion blur
picture, and obtain a clear image based on the obtained fuzzy trajectory
combined with the non-blind deblurring algorithm.
