Rate-dependent seam carving and its application to content-aware image coding
Content-aware image resizing (CAIR) is desired because it preserves prominent regions in a resized image. However, CAIR requires high computational complexity to perform in mobile devices, though it is desired for these displays. Moreover, transmitting the side information for CAIR from the encoder is a problem since it usually requires high bitrates compared with those for image data. In this ...
متن کاملSeam Carving for Content Aware Video Compression
Seam-carving has achieved the most widespread use with the blossom of content-aware resizing methods. This paper proposes the video retargeting method where the aspect ratio and the size of the video are reduced. It deals with the spatial and temporal coherence for the purpose of resizing videos. The proposed algorithm is mainly based on matching-area-based temporal energy adjustment. Each fram...
متن کاملContent Aware Media Retargeting for still images using Seam Carving
ABSTRACT When changing height and width of image traditional techniques for image resizing are oblivious to the content of image. A simple operator seam carving is used for image and video retargeting. This seam carving operator is used for content aware image resizing to reduce or expand image size. According to seam carving method every object in the image must be scaled down proportionally. ...
متن کاملSeam Carving for semantic video coding
Compression standards such as H.264/AVC encode video sequences to maximize fidelity at a given bitrate. However, semantic-oriented and content-aware compression remains a challenge. In this paper, we propose a semantic video compression method using seam carving. Seam carving changes the dimension of an image/video with a non-uniform resampling of each row and column while keeping the rectangul...
متن کاملImproved seam carving for semantic video coding
Traditional video codecs like H.264/AVC encode video sequences to minimize the Mean Squared Error (MSE) at a given bitrate. Seam carving is a content-aware resizing method. In this paper, we propose a semantic video compression scheme based on seam carving. Its principle is to suppress non salient parts of the video by seam carving. The reduced sequence is then encoded with H.264/AVC and the se...
