In this paper, we present an advanced variational formulation based on distance regularized level set evolution(DRLSE)that forces the level set function to be close to a signed distance function, and therefore not only completely eliminates the need of the costly re-initialization procedure, but also allows more efficient numerical scheme than DRLSE and(More)
In current wavelet-based still image compression, the choice of wavelet filter is of great importance, and many issues relating to it remain unresolved. This paper presents a method on linear-regression model based wavelet filter evaluation for image compression. This method analyses several factors (including image’s brightness, image’s(More)
