Abstract: The present disclosure relates to methods and apparatus for image processing. The apparatus can generate object mask information for one or more objects in a first image of a plurality of images in a scene. In some aspects, the first image can be at least one of a downscaled image, a down-sampled image, or a low resolution image. The apparatus can also determine one or more object classifications of the first image based on the generated object mask information. Additionally, the apparatus can identify a modification to at least one of the one or more object classifications based on a second image of the plurality of images in the scene. In some aspects, the apparatus can adjust or maintain the one or more object classifications based on the identified modification to at least one of the one or more object classifications.

Abstract: The present disclosure relates to methods and devices for video or frame processing including an apparatus, e.g., a video or frame processor. In some aspects, the apparatus may receive a video stream including a plurality of frames, each of the plurality of frames including luminance information. The apparatus may also perform a histogram analysis on the luminance information for each of the plurality of frames. Additionally, the apparatus may determine whether a difference between the luminance information for each of the plurality of frames and a current luminance distribution is greater than a perceptual threshold. The apparatus may also calculate an updated tone mapping configuration based on the luminance information for a frame when the difference between the luminance information for the frame and the current luminance distribution is greater than the perceptual threshold.
