Images play a vital role in steganography, as cover media to hide secret messages. Retargeting becomes mandatory while transmitting image in a heterogeneous network because sender and recipient may not have display devices of same resolution. Resizing images by scaling or cropping also lead to loss of visually important features. In steganography, resizing, compressing, and changing the color o...

It is well known that multi-chart parameterization methods introduce seams over the object being parameterized. This causes serious problems for several applications, like texture filtering and simulations in texture domain (e.g. fluid simulations). In this paper we present a set of two techniques, collectively known as ’Continuity Mapping’, that when used together make a multi-chart parameteri...

Texture synthesis through so-called ‘smart copying’ requires a seamless meshing of texture subparts. Current systems first select subparts that seem to globally fit well and then optimise the cut between them on a rather local scale. This order of first selecting patches and then caring about the seamless meshing reduces one’s leeway in the choice of seamless cuts to a small zone of overlap bet...

Gigapixel panoramas are an increasingly popular digital image application. They are often created as a mosaic of smaller images composited into a larger single image. The mosaic acquisition can occur over many hours causing the individual images to differ in exposure and lighting conditions. Therefore, to give the appearance of a single seamless image a blending operation is necessary. The qual...

We present a framework for automatic inspection of welding seams based on specular reflections. To this end, we make use of a feature set – called specularity features (SPECs) – that describes statistical properties of specular reflections. For the classification we use a one-class support-vector approach. We show that the SPECs significantly outperform other approaches since they capture more ...
