| Objective To explore efficient denoise method based on curvelet transfer for medical ultrasonic images. Methods Curvelet denoise method and hidden Markov tree based wavelet method were applied to the ultrasonic images respectively, and fuzzy partition based pixel fusion was applied to the result images. Results A pixel fusion based curvelet denoise approach for medical ultrasonic images was proposed. Conclusion Simulation results of the approach applied to medical ultrasonic images demonstrate that the algorithm improves the visual quality of result images efficiently and suppresses the artifacts in result images evidently. |
