Abstract: The present disclosure provides an image segmentation apparatus, method and relevant computing device. The image segmentation apparatus comprises: a feature extractor configured to extract N image semantic features having different scales from an input image, where N is an integer not less than 3; and a feature processor comprising cascaded dense-refine networks and being configured to perform feature processing on the N image semantic features to obtain a binarized mask image for the input image. A dense-refine network is configured to generate a low-frequency semantic feature from semantic features input thereto by performing densely-connected convolution processing on the semantic features respectively to obtain respective image global features, performing feature fusion on the image global features to obtain a fused image global feature, and performing pooling processing on the fused image global feature to generate and output the low-frequency semantic feature. The semantic features are selected from a group consisting of the N image sematic features and low-frequency semantic features generated by dense-refine networks. The feature processor is configured to obtain the binarized mask image based on low-frequency semantic features generated by the dense-refine networks.

Abstract: An image processing method and an image processing model training method and device. The image processing method comprises: obtaining a first original image to be processed (S101), and downsampling and blurring said first original image according to a configured downsampling processing algorithm and blur parameter to obtain a degraded image (S102). In the method, a new photo can be downsampled and blurred to obtain the degraded image similar to an old photo, and a good training sample is provided for the application of machine learning in the old photo restoration technology. An image processing model applied in the old photo restoration technology is trained on the basis of the training sample, so as to obtain the image processing model having stronger restoration capability, and when the old photo is restored by using the image processing model, the restoration efficiency is higher, and the restoration effect is better.
