Abstract: A method of video evaluation for a video comprising successive video frames comprises the steps of, for successive video frame images: generating a perceptual hash of at least a first portion of a respective image, comparing the generated perceptual hash of a current video frame image with a corresponding perceptual hash of at least one preceding video frame image, and if a difference between the compared perceptual hashes exceeds a predetermined threshold, then identify the one preceding video frame as the boundary of a scene cut within the video.

Abstract: A method of video evaluation includes: for a current video frame, generating two or more metrics from the list consisting of an interframe greyscale delta sum of absolute differences between the current and immediately preceding frame, a first interframe colour delta sum of absolute differences for at least a first colour channel between the current and immediately preceding frame, a second interframe colour delta sum of absolute differences for at least a second colour channel different to the first colour channel between the current and immediately preceding frame, for a first colour channel of the current video frame, a delta between mean and current measurements of a property of the first colour channel, the mean being derived over a predetermined period of time, and for a second colour channel of the current video frame, a delta between mean and current measurements of a property of the second colour channel, the mean being derived over a similar predetermined period of time; generating respective z-scores of the generated metrics; summing the z-scores to generate a frame score for the frame; generating a rolling mean of the frame score over a plurality of frames; and identifying the current video frame for further processing if the frame score for the current frame exceeds the rolling mean for a predetermined number of preceding frames.

Abstract: A method of detecting significant footage for recording from a videogame comprises obtaining position information for a target object within a virtual environment of the videogame, obtaining depth buffer information for a current position of a virtual camera used to generate a current image of the virtual environment for display by the videogame, calculating a first distance along a line between the current position of the virtual camera and the obtained position of the target object, detecting whether a depth buffer value along the line corresponds to at least a threshold distance from the virtual camera, the threshold distance being based upon the calculated first distance, and if so, associating the current image with an indicator that the image is significant for the purposes of recording footage from the videogame.

Abstract: A method of video evaluation for a video comprising successive video frames comprises the steps of generating optical flow vectors for at least a subset of corresponding pixels between frame pairs, calculating a difference between corresponding optical flow vectors of successive frame pairs, and evaluating the resulting differences with respect to a predetermined criterion, to identify respective frame pairs for further processing.

Abstract: An image-based program state analysis method comprises the steps of, for a given image generated by a program, identifying at least a first location within the image occupied by a respective user interface element; identifying in the image a predetermined point on the respective user interface element; identifying the information conveyed by the respective user interface element, with reference to the predetermined point; and outputting the information for subsequent analysis.
