Abstract: A method and apparatus with image enhancement using a base image are provided. The method includes: extracting, by a spatial feature extractor, intra-image spatial feature representations from respective image frames of a burst image set; generating inter-image temporal feature representations based on a local similarity between the spatial feature representations; determining temporal-spatial feature representations of the respective image frames by fusing the spatial feature representations with the temporal feature representations; selecting a base image frame from among the image frames based on the temporal-spatial feature representations; and generating an enhanced image by performing an image enhancement operation on the burst image set based on the base image frame.

Abstract: An electronic device using a spatio-temporal self-similarity (STSS) and a method of operating the electronic device are disclosed. The electronic device may generate an STSS tensor including a spatial self-similarity map and spatial cross-similarity maps for each position of a video feature map corresponding to an input video based on a temporal offset and a spatial offset. STSS feature vectors may be generated from the STSS tensor by decreasing a dimension of the spatial offset and maintaining a dimension of the temporal offset for each position of the STSS tensor. An STSS feature map may be generated by integrating the dimension of the temporal offset for each position of the STSS feature vectors. An inference on the input video may be based on a result of adding the STSS feature map to the video feature map.
