Solution Overview

Problem

Current video fusion technologies require the construction of green screens, leading to high thresholds for implementation and poor user experience due to unrealistic fusion effects, as they often result in images that are predominantly green and differ significantly from actual images.

Innovation Solution

A method for video fusion that involves receiving foreground and background video frames, determining fusion parameters such as color temperature, and processing the foreground video frame based on these parameters to achieve realistic fusion without the need for green screen construction, using modules for video frame reception, fusion parameter determination, object determination, and video fusion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If green screen cutout technology is used for video fusion, then video fusion can be achieved, but the implementation threshold becomes high and the fusion effect becomes unrealistic

Engineering Contradiction:
Improvevideo fusion effectVSAvoidimplementation threshold
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent extracts the background video frame information and uses it to determine fusion parameters (color temperature, brightness, contrast) that are then applied to process the foreground video frame. This eliminates the need for green screen construction by directly extracting and utilizing background scene characteristics for realistic fusion.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent changes the color temperature, brightness, and contrast parameters of the foreground video frame based on the background video frame's fusion parameters. This parameter adjustment approach enables realistic fusion effects without requiring green screen technology, thereby lowering the implementation threshold.

Inventive Principle:

2Reliability

If green screen cutout technology is used for video fusion, then video fusion can be achieved, but the resulting images are predominantly green and differ significantly from actual images

Engineering Contradiction:
Improvevideo fusion effectVSAvoidgreen color distortion
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent determines fusion parameters including color temperature from the background video frame and applies these parameters to process the foreground video frame. This parameter adjustment eliminates green color distortion by matching the foreground's color characteristics to the background's natural color profile, producing realistic fusion results.

3Reliability

If green screen construction is required for video fusion, then fusion can be performed, but the device complexity and construction requirements increase

Engineering Contradiction:
