On the app that you and your friends often share to each other, on the virtual museums that you have usually visited, on the website that you have always loved to wander around their online stores, etc., the AR filters are now everywhere on many digital platforms and even offline performances. However, whether they are created for different purposes, AR filters are sorted in 4 main types with different benefits, they are:

1. Marker-based AR filters: Marker-based augmented reality is a technology that uses a physical marker or image as a reference point to overlay digital content on top of the real-world environment. It works by detecting the marker using a camera and using it as a reference to determine the position and orientation of the virtual content. This allows users to interact with the digital content by moving the marker or their device, creating an augmented reality experience.
2. Markerless AR filters: Markerless augmented reality is a type of AR technology that doesn't require a physical marker or image to overlay digital content on top of the real-world environment. Instead, it uses computer vision algorithms and sensors to detect and track real-world objects and surfaces, and overlays digital content on top of them. This allows users to interact with virtual content in a more natural and intuitive way, without the need for a physical marker.
3. Superimposition-based AR filters: Superimposition-based augmented reality is a type of AR technology that overlays digital content directly on top of the real-world environment, without changing or modifying it. This is done by using a transparent display, such as a heads-up display (HUD), to superimpose digital content onto the user's field of view, making it appear as if it's part of the real world. The digital content is typically anchored to a fixed point in the user's view, such as a physical object or location, and can include text, images, or 3D models. Superimposition-based AR is commonly used in applications such as navigation, where digital directions are overlaid on the real-world environment, or in industrial applications, where workers can see important information overlaid on machinery or equipment while they work.
4. Projection-based AR filters: Projection-based augmented reality is a type of AR technology that projects digital content onto real-world objects or surfaces. This is typically done using a projector, which is used to project images, videos, or other types of digital content onto a physical surface, such as a wall or table. The projected content is then aligned and adjusted to fit the surface, creating a realistic and immersive AR experience. Projection-based AR is commonly used in applications such as advertising, where companies can project interactive ads onto the sides of buildings or other surfaces, or in entertainment, where users can play games or watch videos on large projected surfaces.
