Assignee: TEXAS INSTRUMENTS INCORPORATED
Field: Computer technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 0:
1. A method comprising:
receiving, by a processor, pixel data from an unprotected memory, the pixel data having a level of corruptibility such that failure of any of the pixel data corresponds to corruption of an output data set that is less than or equal to a threshold amount of corruption;
selecting, by the processor, a pixel from the pixel data for filtering, wherein the pixel is associated with a pixel value;
filtering the pixel, by the processor, wherein the filtering includes:
determining, by the processor, a neighbor array of neighboring pixels for the pixel, wherein each of the neighboring pixels have respective pixel values;
determining, by the processor, a minimum value and a maximum value of the respective pixel values of the neighboring pixels in the neighbor array;
comparing, by the processor, the pixel value with the maximum value;
in response to the pixel value being greater than the maximum value, replacing, by the processor, the pixel value with the maximum value representing a first new pixel value of the pixel;
comparing, by the processor, the pixel value with the minimum value; and
in response to the pixel value being less than the minimum value, replacing, by the processor, the pixel value with the minimum value representing a second new pixel value of the pixel; and

outputting, by the processor, one of the pixel value, the first new pixel value, and the second new pixel value, depending on results of the comparing operations, to a memory.
