Efficient Computation of Morse-Smale Complexes for Three-dimensional Scalar Functions
The Morse-Smale complex is an efficient representation of the gradient behavior of a scalar function, and critical points paired by the complex identify topological features and th...

Key-dependency for a wavelet-based blind watermarking algorithm
When a host image is watermarked multiple times by the same algorithm collisions can occur. This makes it difficult for an image to host multiple watermarks. But this hosting is n...
