Solution Overview

Problem

Existing image special effect processing methods fail to achieve good results when applied to whole images, leading to undesirable outcomes.

Innovation Solution

An image special effect processing method that determines a target display region, either foreground or background, and displays a part of the special effect object within that region to enhance the processing result.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If special effect processing is applied to the whole image, then the processing is simple and fast, but the result is poor and looks strange

Engineering Contradiction:
Improveimage processing qualityVSAvoidprocessing complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The image is segmented into foreground region and background region based on depth information. Different special effect objects are selectively applied to different regions, allowing high-quality localized processing without requiring complex processing of the entire image, thus resolving the contradiction between processing quality and complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different display regions (foreground and background) are assigned different special effect objects based on their depth characteristics. This local differentiation approach improves image processing quality by applying appropriate effects to appropriate regions without requiring complex global processing.

Inventive Principle:
Principle #3Local quality

2Manufacturing precision

If special effect object is displayed on the whole image, then the coverage is complete, but the visual effect is poor and strange

Engineering Contradiction:
Improvevisual effect qualityVSAvoiddisplay region area
Core Design Contradiction:
Manufacturing precisionVSArea of stationary object

Solution Approach 1:

The display region is segmented into foreground and background areas using depth information. Special effect objects are selectively displayed in appropriate regions rather than covering the entire image, which improves visual effect quality while maintaining reasonable display coverage.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the image are assigned different display characteristics based on depth information. Foreground regions receive different treatment than background regions, creating superior visual effects without requiring full-image coverage of special effect objects.

Inventive Principle:
Principle #3Local quality

AI summary

The present disclosure discloses an image special effect processing method and apparatus, an electronic device and a computer-readable storage medium. The method includes: in response to an instruction for adding a special effect object on an initial image, determining a target display region of the special effect object on the initial image, where the target display region is a foreground region or a background region of the initial image, the foreground region is an image region where a target object is located in the initial image, and the background region is an image region other than the foreground region in the initial image; and displaying a part of the special effect object located in the target display region on the initial image to obtain a target image. In embodiments of the present disclosure, through determination of a target display region of a special effect object on an initial image, and displaying of the special effect object located in the target display region on the initial image, the special effect object can be displayed differently, thereby achieving a better result.
