The principle of fusing an image into a seamless whole

Edge blending is a technique used to combine multiple image sources into a single cohesive image. This technique is often employed when projecting images onto large screens or walls to achieve a larger image size without visible seams between individual sources. Edge blending also helps eliminate unwanted shading between projectors.

Projection on Large Screens

It involves the digital manipulation of image data to ensure that the projected image accurately matches the specific surface or shape of the projection.

In general, edge blending is used when there is a need to display a relatively wide image over a large area. The video or graphic content of the image must be presented on a continuous surface so that viewers do not see the edges of individual projections.
