JPEG compressed image retrieval via statistical features
To improve e-ciency of compressed image retrieval, we propose a novel statistical feature extraction algorithm in this paper to characterize the image content directly in its compressed domain. The statistical feature extracted is mainly through computing a set of moments directly from DCT coe-cients without involving full decompression or inverse DCT. Following the algorithm design, a content-...
متن کاملTowards Automatic Construction of Diverse, High-quality Image Dataset
The availability of labeled image datasets has been shown critical for high-level image understanding, which continuously drives the progress of feature designing and models developing. However, constructing labeled image datasets is laborious and monotonous. To eliminate manual annotation, in this work, we propose a novel image dataset construction framework by employing multiple textual metad...
متن کاملTime-constrained Jpeg Image Transmission via Variable-quality Coding*
Real-time transmission of high-quality JPEG images is constrained by time, bandwidth, and transmission power in portable devices. To alleviate this problem, we designed, implemented, and evaluated a strategy that can adapt to different compression and transmission rates. (1) It gives important parts of an image higher priorities over unimportant parts. Therefore, the high-priority parts can ach...
متن کاملCompression detection, Image quality, JPEG
The paper presents two methods of prior JPEG-compression detection. In the first method the histogram of chrominance is analysed. In JPEGcompressed images the histogram contains significantly more local maxima than in uncompressed files. The second method is based on neighbouring pixel Ø value difference. In JPEG-compressed image the distribution of these values is different than the distributi...
متن کاملA Blind Steganalysis on JPEG Gray Level Image Based on Statistical Features and its Performance Analysis
This paper presents a blind steganalysis technique to effectively attack the JPEG steganographic schemes i.e. Jsteg, F5, Outguess and DWT Based. The proposed method exploits the correlations between block-DCTcoefficients from intra-block and inter-block relation and the statistical moments of characteristic functions of the test image is selected as features. The features are extracted from the...
