摘要： An image processing method. The method includes: An electronic device obtains N images, where the N images have a same quantity of pixels and a same pixel location arrangement, and N is an integer greater than 1; the electronic device obtains, based on feature values of pixels located at a same location in the N images, a reference value of the corresponding location; the electronic device determines a target pixel of each location based on a reference value of the location; and the electronic device generates a target image based on the target pixel of each location.

摘要： This application discloses an image segmentation method in the field of artificial intelligence. The method includes: obtaining an input image and a processing requirement; performing multi-layer feature extraction on the input image to obtain a plurality of feature maps; downsampling the plurality of feature maps to obtain a plurality of feature maps with a reference resolution, where the reference resolution is less than a resolution of the input image; fusing the plurality of feature maps with the reference resolution to obtain at least one feature map group; upsampling the feature map group by using a transformation matrix W, to obtain a target feature map group; and performing target processing on the target feature map group based on the processing requirement to obtain a target image.

摘要： An image deformation apparatus comprising processors and a memory storing in non-transient form data defining program code executable by the processors to implement an image deformation model. The apparatus is configured to: receive an input image; extract arrangement parameters of a feature from the input image; extract appearance parameters of the feature from the input image; generate deformed arrangement parameters by modifying the location of at least one point of the feature; and render an output image comprising a deformed feature corresponding to the feature in dependence on the deformed arrangement parameters and the appearance parameters. The apparatus may enable the arrangement of the deformed feature of the output image to be controlled while maintaining the overall appearance of the feature of the input image.
