Low-complexity bilateral filter (bf) implementation in a data processing device

A data processing device comprising:

• a memory;
• and
• a processor communicatively coupled to the memory, the processor being configured to execute instructions to:
• implement a BF comprising a spatial filter component and a range filter component,
• implement the spatial filter component with an appropriate function having reduced complexity compared to a Gaussian function to allow for focus on the range filter component,
• determine filter tap value(s) related to the range filter component as a function of radiometric distance between a pixel of at least one of a video frame and an image and other pixels thereof based on a pre-computed corpus of data related to execution of an application in accordance with a filtering requirement of the pixel by the application, and
• constrain the filter tap value(s) to a form i×base to further reduce complexity of filtering of the pixel based on the BF implementation, i being an integer and base being a floating point base.
