Insertion of Irregular-shaped Logos in the Compressed Dct Domain
نویسندگان
چکیده
This paper addresses the problem of the insertion of irregular-shaped objects, such as logos or subtitles, in video signals in the compressed DCT domain. To achieve this objective, a different approach from the usual pixel domain compositing operation is adopted, in order to avoid the presence of undesired semi-transparent regions around the inserted objects. The transposition of this technique to the frequency domain is presented, as well as the inclusion of a logo insertion module in the architecture of a compressed domain video transcoder.

Fast transcoding architectures for insertion of non-regular shaped objects in the compressed DCT-domain
This paper addresses the problem concerned with the insertion of non-regular shaped objects, such as logos or subtitles, in compressed video signals. To achieve this objective, a different approach from the usual pixel-domain compositing operation is adopted, in order to avoid the presence of undesired semi-transparent rectangular regions around the inserted objects. The transposition of this t...
متن کاملMulti-Focus Image Fusion in DCT Domain using Variance and Energy of Laplacian and Correlation Coefficient for Visual Sensor Networks
The purpose of multi-focus image fusion is gathering the essential information and the focused parts from the input multi-focus images into a single image. These multi-focus images are captured with different depths of focus of cameras. A lot of multi-focus image fusion techniques have been introduced using considering the focus measurement in the spatial domain. However, the multi-focus image ...
متن کاملCompressed Domain Implementation of Fuzzy Rule-Based Contrast Enhancement
Since the resolution of images increased in the past few years, the requirements for large storage space and fast process, directly in the compressed domain, becomes essential. Fuzzy rule-based contrast enhancement, is a well-known rather simple approach with good visual results, but as any fuzzy algorithm, it is by default nonlinear, thus not straightforward applicable on the JPEG bitstream (z...
متن کاملA New Approach to Decoding and Compositing Motion- Compensated DCT-Based Images
Multi-point network video services require compositing several video sources into a single displayed video stream. Compositing video directly in the compressed domain can save computations by processing less data and avoiding the conversion process back and forth between the compressed and uncompressed data formats. Earlier work has demonstrated the computational speedup of compositing DCT-comp...
متن کاملVideo Abstraction in H.264/AVC Compressed Domain
Video abstraction allows searching, browsing and evaluating videos only by accessing the useful contents. Most of the studies are using pixel domain, which requires the decoding process and needs more time and process consuming than compressed domain video abstraction. In this paper, we present a new video abstraction method in H.264/AVC compressed domain, AVAIF. The method is based on the norm...
