Embodiment

[0044] This embodiment proposes a recurrent neural network motion blur restoration method, refer to Figure 5 , including the following steps:

[0045] S1, setting the codeword objective function;

[0046] Step S1 specifically includes: the objective function formula is as follows:

[0047]

[0048] Among them, S represents the binary codeword sequence, F() represents the discrete Fourier transform operation, min() represents the calculation of the minimum value operation, var() represents the calculation of the variance operation, n represents the length of the binary codeword, α 1 , α 2 represent their respective weight coefficients. In the experiment, their respective full weight coefficients are a 1 = 0.4, a 2 = 0.6. Coded exposure imaging is the latest imaging mode, which changes the low-pass filter in traditional imaging to a band-pass filter, enabling it to retain more image detail information during the imaging process.

Abstract

The invention provides a recurrent neural network motion blur restoration method. The method comprises the following steps: setting a codeword target function; obtaining an optimal code word through agenetic algorithm; obtaining a blurred image; preprocessing the data to generate a data set; training a long-term and short-term memory network by utilizing the data set; and inputting the test imageinto the trained long-term and short-term memory network to obtain a restored image. According to the method, a coding exposure imaging mode is adopted, optimal code word search is carried out according to coding requirements, a long-term and short-term memory network is adopted for network training, and finally a high-resolution image is obtained through training.

Description

technical field [0001] The invention relates to the field of computational optical imaging and the field of deep learning technology, in particular to a motion blur restoration method of a cyclic neural network. Background technique [0002] Motion blur image restoration has always been an important research topic in image restoration. The main cause of motion blur is that when shooting a moving target, the relative motion between the moving target and the imaging system often occurs within the exposure time of the camera, resulting in motion blur in imaging and a decrease in image resolution. In the traditional imaging process, the camera shutter is always open, and there must be many zeros in the frequency domain on the convolution filter, which makes the filter irreversible and makes motion blur a pathological problem. [0003] In order to solve the pathological problem of motion blurred images, researchers conduct research from two perspectives: image imaging mode and d...
