摘要： The present disclosure relates to a method of stabilizing bounding boxes for objects in a video stream, the method comprising: receiving a video stream comprising a sequence of image frames; detecting an object in the image frames and generating a bounding box surrounding the object; measuring a noise level for the video stream; and temporally filtering the bounding box over a plurality of image frames based on the measured noise level, thereby stabilizing the bounding box in the video stream. The disclosure further relates to an image processing system.

摘要： This application provides a video processing method and an electronic device, and pertains to the field of terminal technologies. The method includes: receiving a first operation input by a user; obtaining a first image in a preset default high-dynamic range HDR exposure manner in response to the first operation; obtaining ambient brightness based on the first image, and determining a target HDR exposure manner based on a preset policy, where the preset policy includes a dynamic range corresponding to video shooting, a flicker status, and a correspondence between the ambient brightness and the target HDR exposure manner; and when the target HDR exposure manner is different from the default HDR exposure manner, switching the default HDR exposure manner to the target HDR exposure manner, and continuing to perform the video shooting. In the method, seamless automatic switching is performed between a plurality of exposure manners based on an actual video shooting situation, thereby implementing efficient HDR processing in a video shooting scenario and improving video picture quality.

摘要： A method performed by an electronic device is described. The method includes obtaining a first image from a first camera, the first camera having a first focal length and a first field of view. The method also includes obtaining a second image from a second camera, the second camera having a second focal length and a second field of view disposed within the first field of view. The method further includes aligning at least a portion of the first image and at least a portion of the second image to produce aligned images. The method additionally includes fusing the aligned images based on a diffusion kernel to produce a fused image. The diffusion kernel indicates a threshold level over a gray level range. The method also includes outputting the fused image. The method may be performed for each of a plurality of frames of a video feed.

摘要： Provided are a method and apparatus for generating an image reconstruction model and an image reconstruction method and apparatus using the image reconstruction model. The image reconstruction apparatus extracts, through an encoder configured to extract a structure and a texture, a structure and a texture of each of a first medical image and a second medical image and generates, through a decoder configured to reconstruct an image based on a structure and a texture, a third medical image in which the texture of the second medical image is combined with the structure of the first medical image.
