Embodiment Construction

[0081] Such as Figure 1-3 As shown in one of the above, the present invention proposes a method for repairing and reproducing old movies based on deep learning. The repair process mainly includes de-interlacing, video de-noising, video de-blurring, video interpolation and super-resolution technology. The specific process is as figure 1 shown. All convolution layers in the present invention use a convolution kernel with a size of 3×3, and the specific steps are as follows:

[0082] Step 1: Extract frames from the video through ffmpeg, and form the training data set of the deinterlacing model, the training data set of the video frame interpolation model, the training data set of the deblurring network and the training data set of the super-resolution model;

[0083] Step 1.1: Form a training data set for the deinterlacing model (model1):

[0084] Step 1.1.1: Extract frames from the video through ffmpeg to obtain each frame of image, scan the obtained video frames in even fie...

Abstract

The invention discloses a method for repairing and reproducing old films based on deep learning, which includes the following steps: S1, extracting the frames of a video through ffmpeg, and forming training data sets of a de-interlacing scanning model, a video frame interpolation model, a de-blurring network and a super-resolution model respectively; S2, training a de-interlacing scanning networkmodel; S3, training a video frame interpolation network model; S4, training a de-blurring network; S5, training a super-resolution network; and S6, training a de-noising network. In the invention, oldfilms are repaired by using de-interlacing scanning, video de-noising, video de-blurring, video frame interpolation and super-resolution technologies based on deep learning. Compared with manual operation, the stability is higher, the computing speed is improved, and the accuracy of image restoration is improved. The method has the advantages of good restoring effect of processed images, high clarity of restored images, convenience of use, low cost, and the like.

Description

technical field [0001] The present invention relates to deep learning and computer vision, in particular to a method for repairing and reproducing old films based on deep learning. Background technique [0002] Film cultural heritage is a precious memory of a country and a nation, an important part of the future intangible cultural heritage, and an excellent carrier for modern Chinese culture to go global. For traditional red movies and movies that reflect the positive spirit of hard work in modern China, modern technology can be used to restore and present them more fully. However, due to the limitations of shooting technology in the past, a large number of old films can no longer meet people's viewing needs for high-definition vision. [0003] There are a huge number of film reels in my country that need to be restored. There are 20,000 to 30,000 feature films in existence, but now only about 60 old film reels can be repaired each year. According to the current restorati...
