Matching pursuit (MP) is a sparse approximation algorithm which finds the "best matching" projections of multidimensional data onto the span of an over-complete (i.e., redundant) dictionary $${\displaystyle D}$$. The basic idea is to approximately represent a signal $${\displaystyle f}$$ from … Pogledajte više • The algorithm converges (i.e. $${\displaystyle R_{n}\to 0}$$) for any $${\displaystyle f}$$ that is in the space spanned by the dictionary. • The error $${\displaystyle \ R_{n}\ }$$ decreases monotonically. Pogledajte više Matching pursuit has been applied to signal, image and video coding, shape representation and recognition, 3D objects coding, and in interdisciplinary applications like structural health monitoring. It has been shown that it performs better than DCT based … Pogledajte više A popular extension of Matching Pursuit (MP) is its orthogonal version: Orthogonal Matching Pursuit (OMP).
