transformation techniques, it serves as the foundation for other techniques: as will be seen in the upcoming subsections, it serves as the foundation for most of thespatial domaintechniques, such as pixel-value differencing (PVD), least significant bit matching (LSBM) and other spatial domain ...
Recent advancements in tissue imaging techniques have facilitated the visualization and identification of various cell types within physiological and pathological contexts. Despite the emergence of cell-cell interaction studies, there is a lack of methods for evaluating individual spatial interactions. In thi...
The method presented gradually spreads the watermark information over a region of pixels as implemented by the transform domain techniques. Thus the method is designed to deliver the two essential features required of watermarking systems namely, high image quality and high robustness to attacks. Also...
Time-domain analog calculations process pulse signals from limited input ports6,7. In stark contrast, spatial analog computing modulates incident wavefronts in real space, enabling massive and high-throughput parallel operations for required signal-processing tasks such as spatial differentiation8,9,10,...
