This algorithm reduces the radial gradient thus revealing the features in the sun's corona.
It reduces the dynamic range of the image by normalizing the pixel values at different scales (or standard deviation) using Gaussian kernels. It highlights the information embedded on the solar surface.
Designed to trace the magnetic field loops over the surface of the sun.
It helps in calculating the 2D velocity flow field between two images taken at some time instant apart from each other. An existing C code was wrapped using Cython to make it available to the Python API.
