System object: vision.MedianFilter
Perform median filtering on input image
I2 = step(H,I1)
I2 = step(H,I1,PVAL)
I2 = step(H,I1) performs median filtering on the input image I1 and returns the filtered image I2.
I2 = step(H,I1,PVAL) performs median filtering on input image I1, using PVAL for the padding value. This option applies when you set the OutputSize property to Same as input size, the PaddingChoice property to Constant, and the PaddingValueSource property to Input port.
Note: The object performs an initialization the first time the step method is executed. This initialization locks nontunable properties and input specifications, such as dimensions, complexity, and data type of the input data. If you change a nontunable property or an input specification, the System object™ issues an error. To change nontunable properties or inputs, you must first call the release method to unlock the object.
