Optimization of Matching Pursuit Encoder Based on Analytical Approximation of Matching Pursuit Distortion [PDF]
2006 IEEE International Conference on Multimedia and Expo, 2006 Distortion of matching pursuit is calculated in terms of matching pursuit encoder parameters for uniformly distributed signals and dictionaries. Then, the MP encoder is optimized using the analytically derived approximation for MP distortion. Our simulation results show that this optimized MP encoder exhibits optimum performance for nonuniform signal ...
