In the reverse engineering of double JPEG compression in the presence of image resizing between the different compressions detectors. The approach is based on the fact that previously JPEG compressed images tend to have a near lattice distribution property (NLDP), and that this property is usually maintained after a simple image processing step and subsequent recompression. The proposed approac...

The contour tree file format has been used for a few years as a suitable storage format for most image types. The technique stores unique regions into a hierarchical data structure which defines the complete raster image. This data structure is called a contour tree. It compares very favourable with other lossless coding schemes on all image format types including, bi-level and reduced colour i...

The ability to read and write Javanese scripts is one of the most important competencies for students have in order preserve language as Indonesian cultures. In this study, we developed a predictive model 20 characters using random forest algorithm basis developing script learning media students. building model, used an extensive handwritten image dataset experimented with several different pre...

Dynamic link resizing is an attractive approach for resource management in virtual private networks (VPNs) serving modern real-time and multimedia traffic. In this paper, we assess the use of linear traffic predictors to dynamically resize the bandwidth of VPN links. We present the results of performance comparisons of three predictors: Gaussian, autoregressive moving average (ARMA) and fractio...

A graph theoretic approach is proposed to formulate communication graphs that enable ultrafast information distribution. In our earlier work, we reported that Borel Cayley graph (BCG) is potentially a good candidate as a logical topology for fast information distribution. However, the practical applications of BCG have been challenging because of its inflexible sizes. In this paper, we propose ...

Digital image data are now commonly used throughout the field of solar physics. Many steps of image data analysis, including image co-alignment, perspective reprojection of the solar surface, and compensation for solar rotation, require re-sampling original telescope image data under a distorting coordinate transformation. The most common image re-sampling methods introduce significant, unneces...

This is generally done due to the largely available contemporary editing software and superior digital cameras. Authenticity of images becomes a more im...

Problem statement: Fast and accurate interpolation and resizing of images and video frames is a much sought after research area in multimedia applications. The more accurate schemes are computationally expensive and require more time for execution. We proposed here Discrete Wavelet Transform (DWT) using lifting scheme as an accurate and computationally inexpensive interpolation technique for im...

Digital image processing heavily relies on the connectivity of pixels, as it is a vital component for accurate object identification and analysis within an image. Grouping together pixels with similar features such colour intensity, allows formation meaningful patterns or objects, which essential recognition segmentation. This approach particularly valuable in photogrammetric imaging, video sur...
