It allows you to naturally add any object to any video scene, such as inserting a car in a video of walking on the street or adding a chair to an indoor video.
And ensure that the position, lighting effect and overall style of the added objects are perfectly integrated with the original video, just as if they were there.
Main features:
1. Accurate placement of objects: Ensure that the position of newly inserted objects in the video looks natural and reasonable, and is consistent with other elements and spatial layout of the video scene.
2. Real simulation of lighting and shadows: By analyzing and simulating the lighting conditions in the video and their impact on objects, generate natural-looking shadows and lighting effects to enhance the integration of objects and the environment.
3. Style consistency: Apply style conversion technology to adjust and optimize the visual effects of the video, so that the inserted objects are consistent with the background video in terms of color, texture, etc., further improving the realism and quality of the entire video.
Working principle:
1. Geometric positioning and object placement:
First, the technology uses advanced object recognition and scene understanding algorithms to analyze the environment in the video, including identifying spatial layout, object location and scene depth information in the video.
It then calculates the best position for the new object in the scene, ensuring that it is correctly aligned with other objects and terrain in the environment to maintain geometric consistency.
2. Illumination estimation and simulation:
By analyzing the lighting conditions in the video, including the direction, intensity of the light source, and the reflection and scattering effects of light on different surfaces, this technology can accurately estimate the lighting environment of the scene.
It then simulates how to apply the same lighting effects to newly added objects, including generating realistic shadows to ensure that the objects appear to blend naturally into the lighting environment in which they are located.
3. Style conversion and visual consistency:
Use style conversion technology to adjust the visual attributes of the inserted object, such as texture, color, and contrast, to align it with the style of the surrounding environment.
In this way, not only do the geometry and lighting effects of the object match with the original video, but its visual style is also integrated with the background scene, improving overall visual coordination.
4.Dynamic Media Processing Service:
In order to maintain the stability and consistency of objects in consecutive video frames, the technology uses dynamic tracking and video stabilization technology to ensure that as the scene changes, inserted objects can naturally move and adapt to new perspectives and positions.
This includes handling changes in perspective caused by camera motion to ensure that objects remain in the correct position and orientation throughout the video sequence.
