What is the primary function of digital filters in DXR?

The primary function of digital filters in DXR is to enhance or suppress certain features in an image. This capability allows for improved visualization and analysis by manipulating specific aspects of the image data. Digital filters can adjust the contrast, emphasize edges, or reduce noise in an image, enabling clearer diagnostics and better interpretation of the visual information.

The other choices, while they describe processes involved in image processing, do not capture the essential role of digital filters. Reducing image file size can be a byproduct of other processes, but it is not the main function of filtering. Converting images to black and white is a form of image alteration but does not relate directly to feature enhancement or suppression. Eliminating motion blur is also a technique that may be employed in image processing, but it is specific to stabilization rather than enhancing or suppressing image features overall. Thus, the role of digital filters is squarely focused on modifying image characteristics to aid in analysis and interpretation, making enhancement or suppression of features their primary function.
