Abstract

The embodiment of the invention provides a method and device for eliminating moire patterns in an image. The method comprises the steps that a target image containing the moire patterns is acquired; inputting the target image into a preset generator, and taking the output of the generator as a moire elimination image corresponding to the target image, wherein the generator is a deep convolutionalneural network which is obtained through training by applying a preset generative adversarial network and is used for eliminating moire in the image. According to the method and the device, the elimination efficiency of the moire in the image can be effectively improved, the quality of the image after moire elimination can be effectively improved, and the definition of the image after moire elimination can be effectively improved.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to a method and device for eliminating moiré in images. Background technique [0002] Digital devices allow us to conveniently record the beautiful moments in our lives. With the iterative improvement of hardware performance, although the quality of digital images continues to improve, it is still difficult to obtain high-quality images on the shooting screen. Due to the asynchronous sampling frequency between the camera sensor and the screen, the overlay effect between the pixel grid of the camera and the screen causes the image output by the camera to be disturbed by moiré. [0003] At present, in the field of computer vision, there are two main types of moiré removal algorithms: the frequency band separation algorithm based on traditional image processing and the moiré removal algorithm based on convolutional neural network, both of which have serious loss of ...
