Image Background Replacement Using Location Metadata
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face challenges in replacing the background of images with visually appealing alternatives, as they often lack information about the geographic location of the original image and struggle to find suitable replacement images that match the original's parameters, leading to undesirable results.
Innovation Solution
The system uses image-processing algorithms to identify the object and background of an image, determine the geographic location, and retrieve matching images from a database, selecting one based on parameters like size, orientation, and lighting conditions to generate a new image with a realistic appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If users manually search for replacement images without location information, then they can find images, but the process is time-consuming and results in undesirable appearances
Solution Approach 1:
The system performs preliminary actions by automatically determining the geographic location of the original image using image processing algorithms and metadata extraction before the user needs to find a replacement image. This pre-computed location information enables rapid retrieval of suitable replacement images from databases, eliminating manual search while ensuring visual realism through location-based filtering.
Solution Approach 2:
The patent introduces an intermediary system that bridges the original image and potential replacement images through geographic location metadata. This intermediary layer of location information allows the system to automatically match and retrieve visually appropriate replacement images based on spatial correspondence, resolving the contradiction between quick retrieval and visual quality.
2Ease of operation
If users replace background without matching parameters, then the process is simple, but the resulting image has undesirable appearance
Solution Approach 1:
The system automatically extracts and compares multiple visual parameters including geographic location, lighting conditions, time of day, weather, and compositional elements. By changing and matching these parameters between the original and replacement images, the system maintains visual realism while keeping the user interface simple. The parameter matching happens automatically in the background, requiring minimal user input.
Solution Approach 2:
The system performs self-service by automatically analyzing the original image's parameters and autonomously selecting the most suitable replacement image without requiring extensive user input or manual adjustment. The algorithm independently evaluates multiple images against extracted parameters and presents the best match, maintaining ease of operation while ensuring high visual matching quality.
3Productivity
If the system retrieves images without considering multiple parameters, then the process is efficient, but the selected image does not match the original
Solution Approach 1:
The patent segments the image analysis process into distinct parameter categories: geographic location, temporal information (time of day, season), environmental conditions (weather, lighting), and compositional elements. By segmenting these dimensions, the system can efficiently retrieve images matching each parameter independently using database indexing, then combine results to achieve high overall matching accuracy without sacrificing speed.
Solution Approach 2:
The system performs preliminary extraction and indexing of multiple parameters from original images during the upload phase. This pre-processing creates ready-to-query data structures that enable rapid retrieval operations. When a background replacement is needed, the pre-extracted parameters allow the system to quickly filter and rank candidate images without real-time analysis, maintaining both speed and precision.

AI summary
Systems and methods are described for replacing a background portion of an image. An illustrative method includes receiving a first image, identifying a background portion of the first image and a subject portion of the first image, retrieving metadata associated with the first image, determining, based on the metadata, a geographic location where the first image was captured, retrieving a plurality of other images captured at the geographic location, selecting a second image from the plurality of other images, wherein the second image is associated with metadata indicating that the second image was captured during a predetermined time period, and generating for display a third image comprising the subject portion of the first image placed over the second image.
