First Claim
Patent Images

1. method that reduces the spatial domain noise of image comprises:

  • Obtain an object pixel and set up an operational block according to this;

    The pixel value of this object pixel in this operational block and a plurality of neighborhood pixels is carried out computing and obtain a variance that should operational block;

    Judge according to this variance whether this object pixel has feature;

    If this object pixel does not have feature, then those pixels in this operational block are carried out a filtering operation and obtain an adjustment pixel value;

    AndThe pixel value that upgrades this object pixel is this adjustment pixel value.
