Abstract. The design of critical embedded real-time systems requires high confidence in the architecture and the implemented functionalities. Classically, such functions are suppor...
In this paper, watermarking for still image is proposed. Image watermarking is performed in spatial domain that not only easy but also good result. A watermark image as binary ima...
We present a simple and scalable graph clustering method called power iteration clustering (PIC). PIC finds a very low-dimensional embedding of a dataset using truncated power ite...
Watermark perceptibility and robustness must be ensured in order to enhance the practicality of digital watermarking. Taking human visual system characteristics into account fully...
This paper presents a fast method to compute homeomorphisms between 2D lattices and shapes found in binary images. Unlike many other methods, this mapping is not restricted to sim...
