Problems solved by technology
[0004] However, in a dual-dynamic environment, there are many reasons for image blurring. If only one blurring factor is used to construct a blurring kernel to process the image, then other blurring factors cannot be deblurred, so that the image after deblurring Can't achieve enough clarity

Embodiment Construction
[0028] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.
[0029] In a dual-dynamic environment, there are many reasons for image blur, among which the two most important reasons are the defocus blur caused by motion blur kernel distance changes. The method provided by the embodiment of the present invention establishes a dual-dynamic The motion blur kernel and defocus blur kernel model of the blurred image, use the motion blur kernel and defocus blur k...

The invention relates to a method for restoring a double dynamic blur image, which includes: acquiring a double dynamic blur image y, establishing an image pyramid of the double dynamic blur image, and establishing a motion blur kernel and a defocus blur kernel of the double dynamic blur image y based on the image pyramid. , among which, the resolution of the blurred image in the image pyramid increases sequentially from the top to the bottom; calculate the motion blur kernel, defocus blur kernel and the optimal value of the clear image of the current layer in the image pyramid; calculate the motion blur based on the current image layer kernel, defocus blur kernel and the optimal value of the clear image, calculate the motion blur kernel, defocus blur kernel and the optimal value of the clear image of the next image layer until the clear image at the bottom of the image pyramid is calculated. The method provided by the embodiment of the present invention estimates the clear image in the process of continuously optimizing the motion blur kernel and the defocus blur kernel, so that the clear image reaches sufficient clarity.
Description
technical field [0001] The invention relates to the technical field of image processing, in particular to a method for restoring double motion blurred images. Background technique [0002] As time goes by, the tentacles of "mobile electronic eyes" will penetrate into every corner of the city and play an increasingly important role in protecting our "safe city". A safe city is also an important measure of a city's modern management level, and an important measure to realize the security and stability of a city and even the entire country. Only by establishing a reasonable and effective urban video surveillance management system can the government management department discover problems at the first time and propose countermeasures and emergency plans. [0003] The monitoring devices in the urban video surveillance management system, such as cameras and surveillance videos, often capture blurry images. In order to obtain clear images, in the prior art, the blurred images are ...
