Title:
METHOD, APPARATUS AND DEVICE FOR ELIMINATING IMAGE NOISE AND CONVOLUTIONAL NEURAL NETWORK
Document Type and Number:
WIPO Patent Application WO/2018/018470
Kind Code:
A1
Abstract:
Disclosed are a method, apparatus and device for eliminating image noise and a convolutional neural network. The method comprises: obtaining a generation scene of an image to be denoised; obtaining, from a correlation between a pre-set scene and a network weight coefficient, the network weight coefficient corresponding to the current generation scene, wherein the network weight coefficient comprises a convolution weight coefficient and a synthesis proportion coefficient; according to the convolution weight coefficient corresponding to the current generation scene, adjusting a convolution weight coefficient of a convolution unit at each convolution layer in the convolutional neural network; according to the synthesis proportion coefficient corresponding to the current generation scene, adjusting a proportion coefficient of a convolution operation result output by different convolution units in the last convolution layer synthesized by an output layer in the convolutional neural network; and by using the adjusted convolutional neural network, denoising the image to be denoised. By means of the method, apparatus and device and the convolutional neural network provided in the present invention, the denoising effect for an image can be improved.
