Nonlocal means method using weight refining for despeckling of ultrasound images
An extension of nonlocal means method to ultrasonic speckle reduction. Weight refining scheme in a lower dimensional PCA subspace. Automatic termination of weight refining scheme using mean absolute error based on an estimated fully formed speckle region. Superior restoration performance compared with existing ultrasound image despeckling methods. Great potential applications to medical ultrasound imaging.
