Performance of a Robust Filter-based Approach for Contour Detection in Wireless Sensor Networks
—A robust filter-based approach is proposed for wireless sensor networks for detecting contours of a signal distribution over a 2-dimensional region. The motivation for contour d...

Contour Detection by Multiresolution Surround Inhibition
In natural images, luminance changes occur both on object contours and on textures. Often, the latter are stronger than the former, thus standard edge detectors fail in isolating ...

Spatio-Temporal Continuous Wavelet Transforms for Motion-Based Segmentation in Real Image Sequences
The purpose of this paper is to develop a motionbased segmentation for digital image sequences that is based on continuous wavelet transform. Continuous wavelet transform allows e...

Color and Scale: The Spatial Structure of Color Images
Abstract. For grey-value images, it is well accepted that the neighborhood rather than the pixel carries the geometrical interpretation. Interestingly the spatial configuration of ...

On the use of discrete Pascal transform in hiding data in images
The Discrete Pascal Transform (DPT) has been proved remarkably useful for edge detection, filter design, discrete-time signal interpolation and data hiding. In the present work a n...
