Content-aware video resizing using discontinuous seam carving

摘要

A video is resized while preserving salient regions within the video. The dimensions of the video are reduced by selectively removing unimportant, or less salient, pixels from the video in a manner that diminishes any resulting spatial and temporal artifacts. More specifically, “seams” of pixels are selectively removed from frames of the video, where a “seam” is a horizontal or vertical chain of pixels through a frame. A seam can be selected from among all possible pixels in a row or column, thereby allowing discontinuous seams. Seams are selected using a technique that encourages the seam to pass through less-salient regions of the frame, and that reduces spatial artifacts when the video is played.
