Basbild

Basbild is a term used in some Scandinavian language contexts to denote a base image. In image processing, basbild refers to the primary reference image that serves as a frame for analysis, alignment, or compositing. It is often the image from which features are extracted or to which subsequent images are registered, aligned, or subtracted. In video surveillance and computer vision, the basbild can function as the background model against which foreground objects are detected, or as the first frame in a sequence used for motion estimation.

In photography and digital art pipelines, the basbild can be the original photograph used as the starting point for edits, layering, color grading, or transformations. When multiple images are combined, the basbild is typically designated as the anchor image to preserve color space, perspective, or exposure reference.

Etymology and usage: basbild is a compound of bas (base) and bild (image) in several Germanic languages. Cognates include basisbild in German and basbild in other Nordic contexts, though exact usage varies by field and language. The concept is broadly equivalent to terms like reference image, base image, or background image in English.
