<p>Video/image analysis and compression systems are described, that can be used in conjunction with image, video, and/or sound files. A master image can be created from a series of images. The difference between the next image and the master image is compared and is placed in a key frame located within a video file. Areas of the next image that differ from the master image are cropped and the XY anchor positions of the cropped area in relation to the master image are recorded. These areas are then placed in the next sequential key frame. The master image would underlie the sequential cropped areas. Optionally, transparent alpha channels can be applied to the areas that are different from the master image within the cropped areas. The new image is then stored. This procedure would be repeated until no further images from the image series are present.</p> |
