Abstract
A method of identifying a representative image of a video stream is provided. Similarity between video frames of a primary video stream relative to video frames of a different secondary video stream having similar content is evaluated and a video frame from the primary video stream having a greatest extent of similarity relative to a video frame of the secondary video stream is identified. The identified video frame is selected as an image representative of the primary video stream and may be used as an informative thumbnail image for the primary video stream. A video processing electronic device and at least one non-transitory computer readable storage medium having computer program instructions stored thereon for performing the method are also provided.
