Overlay is a technique used in digital image processing where multiple images or video streams are combined or superimposed on top of each other to create a composite image. It is widely used in various applications such as computer graphics, video editing, virtual reality, and augmented reality.

There are several ways to achieve overlaying in image processing. One common method is to use a binary mask, also known as an alpha mask, to specify which parts of the Overlay image should be visible or transparent. The mask contains information about the opacity or transparency of each pixel in the overlay image, allowing the underlying image to show through.

Overlaying can be used to add visual effects or enhance the appearance of an image. For example, in video editing, overlaying can be used to add titles, captions, or graphics on top of a video stream. In computer graphics, overlaying can be used to combine multiple layers of images or textures to create a more complex and visually appealing final image.

Overlaying is also a key component in augmented reality (AR) systems. AR Overlays digital information or virtual objects onto the real world in real time. For example, a user wearing AR glasses can see virtual objects superimposed on their view of the physical world. Overlaying techniques are used to align and blend the virtual objects seamlessly with the real environment.

In recent years, overlaying has become increasingly important in the field of virtual reality (VR). VR systems use overlaying to combine virtual images with the user's view of the real world, creating an immersive and interactive experience. For example, in a VR game, overlaying can be used to display a virtual scoreboard or health bar within the user's field of view.

Overlaying can also be used to create composite images by blending multiple images or video streams together. This can be done using different blending modes such as additive, subtractive, or multiplicative blending. Each blending mode has its own mathematical formula that determines how the pixels from the overlay image are combined with the pixels from the underlying image.

In addition to blending, overlaying can also involve other image processing operations such as color correction, edge detection, or image warping. These operations can be applied to either the overlay image or the underlying image before they are combined together.

Overall, overlaying is a powerful technique in digital image processing that allows for the creation of visually appealing and interactive images or videos. It has a wide range of applications in various fields such as computer graphics, video editing, virtual reality, and augmented reality. As technology continues to advance, the use of overlaying is likely to become even more prevalent in the future.
