Abstract :
A post-processing detector for Atomic Decomposition in order to evaluate the quality of the extracted signal components is presented. It improves the signal representation and can work in a noisy environment. Its advantages over High Resolution Pursuit are investigated along with its application to the combination of two types of dictionaries to achieve high detection performance and high resolution.
