Wavelet Based Authentication/Secret Transmission Through Image Resizing(WASTIR)
The paper is aimed for a wavelet based steganographic/watermarking technique in frequency domain termed as WASTIR for secret message/image transmission or image authentication. Number system conversion of the secret image by changing radix form decimal to quaternary is the pre-processing of the technique. Cover image scaling through inverse discrete wavelet transformation with false Horizontal ...
متن کاملContent-based Image Resizing on Mobile Devices
Content-aware image resizing are effective algorithms that allow to take into account the visual content of images during the resizing process. Despite the technological advances in the context of mobile devices, content-aware image resizing algorithms are still far to be used on a hand held device due to the computational resources needed during the resizing. In this paper we afford this probl...
متن کاملHigh quality image resizing
An increasing amount of display devices with fixed sizes call for an adaptive strategy for optimal display. For this purpose, content aware image resizing techniques are developed. Previous works mainly lay their attention on the shrinkage operation of the examined image. Less efforts are paid on the expansion manipulation. Though some literatures claim an extension of their shrinkage operation...
متن کاملAutomatic Image Resizing
Today’s digital content is displayed on a diverse set of devices, ranging from large monitors of various aspect ratios, to small screens of cell phones or handheld devices. Existing display standards, such as HTML, support the ability to dynamically resize the composition of the page to enable viewing on different display sizes. During this resizing process, images always remain fixed in size. ...
متن کاملContent-Aware Geometry Image Resizing
Polygonal meshes are widely used to represent the shape of 3D objects and the generation of multi-resolution models has been a significant research topic in computer graphics. In this paper, we demonstrate how to generate multi-resolution models through 2D image processing techniques. The goal of generating multi-resolution models is accomplished by resizing the corresponding geometry images of...
