A system collects a training dataset for training an artificial intelligence (AI) model. The system receives high-resolution (HR) images and information of one or more regions-of-interest (ROIs) in the HR images. The system maps a stride distribution to the ROIs, and samples the HR images with non-uniform strides according to the ROIs and the stride distribution to generate corresponding low-resolution (LR) images. The system then trains the AI model to perform super-resolution (SR) operations using training pairs formed by the HR images and respective corresponding LR images.

Region-of-interest (ROI) guided sampling for AI super resolution transfer learning feature adaptation

Aspects of the disclosure provide a frame processor for processing frames with aliasing artifacts. For example, the frame processor can include a super-resolution (SR) and anti-aliasing (AA) engine and an attention reference frame generator coupled to the SR and AA engine. The SR and AA engine can be configured to enhance resolution and remove aliasing artifacts of a frame to generate a first high-resolution frame with aliasing artifacts and a second high-resolution frame with aliasing artifacts removed. The attention reference frame generator can be configured to generate an attention reference frame based on the first high-resolution frame and the second high-resolution frame.

AI frame engine for mobile edge

Aspects of the disclosure provide a device for processing frames with aliasing artifacts. For example, the device can include a motion estimation circuit, a warping circuit coupled to the motion estimation circuit, and a temporal decision circuit coupled to the warping circuit. The motion estimation circuit can estimate a motion value between a current frame and a previous frame. The warping circuit can warp the previous frame based on the motion value such that the warped previous frame is aligned with the current frame and determine whether the current frame and the warped previous frame are consistent. The temporal decision circuit can generate an output frame, the output frame including either the current frame and the warped previous frame when the current frame and the warped previous frame are consistent, or the current frame when the current frame and the warped previous frame are not consistent.
