  • Integration of filters and phase unwrapping algorithms for removing noise in image reconstruction
    Patent number: 9020293
    Abstract: A method to detect and remove noise in image reconstruction. The method includes integration of filters and phase unwrapping algorithms for removing speckle noise, residual noise and noise at the lateral surface of height discontinuities. The method is used for generating a noise-free unwrapped phase map and hence, a successful image reconstruction of an object image.
