Speckle filtering in image processing

A method comprising:

• determining, with one or more processors and for each of a plurality of columns in a window centered on a subject pixel in an image, one or more partial speckle regions;
• determining, with the one or more processors and based on the one or more partial speckle regions for each of the plurality of columns, a speckle size of the subject pixel;
• determining, with the one or more processors and based on the speckle size of the subject pixel, to remove noise associated with the subject pixel from the image;
• and
• removing, with the one or more processors, the noise associated with the subject pixel from the image.

A computer-readable storage medium storing instructions thereon that when executed cause one or more processors to:

• determine, for each of a plurality of columns in a window centered on a subject pixel in an image, one or more partial speckle regions;
• determine, based on the one or more partial speckle regions for each of the plurality of columns, a speckle size of the subject pixel;
• determine, based on the speckle size of the subject pixel, to remove noise associated with the subject pixel from the image;
• and
• remove the noise associated with the subject pixel from the image.
