A portable image enhancement device comprising an optical image sensor, a rangefinder, a parametric control, a central processing unit (CPU), and a user interface. The sensor receives image data for a target object in a tactical scene. The rangefinder continually measures distance from the device to the target object, which may be in motion relative to each other. The parametric control tunes a parametric variable (e.g., spatial frequency, filter shape, orientation) that the CPU uses, along with the potentially-changing target distance, to create custom spatial filters and apply them to create a filtered scene from the tactical scene. Each spatial filter is of a two-dimensional (2D) Fourier-domain type (e.g., high-pass, low-pass, band-pass, band-stop, orientation). A spatial filter, target distance, and parametric variable combination may be stored as a preset filter for subsequent retrieval and application to a newly-input tactical scene. The user interface displays dynamically-tunable filtered scene(s).
