Solution Overview

Problem

Existing visual search technologies face challenges in efficiently segmenting regions of interest in digital images, particularly in large-scale e-commerce contexts where product images vary significantly in pose and background, making off-the-shelf automated segmentation routines ineffective.

Innovation Solution

A supervised learning-based system that predicts a sequence of image processing steps to identify the region of interest, using a classifier trained on images with known optimal processing steps, and applies these steps to segment images in a content-based retrieval system, allowing for offline processing and efficient query-time searches.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If fully automated segmentation approaches are used, then productivity is improved, but segmentation quality deteriorates due to inability to handle diverse product appearances

Engineering Contradiction:
Improveautomation levelVSAvoidsegmentation quality
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The system performs preliminary clustering of images based on layout similarity before segmentation. By grouping images with similar layouts together and pre-determining segmentation parameters for each cluster, the system prepares segmentation strategies in advance, enabling both high automation and high quality segmentation for diverse product appearances

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system automatically adjusts segmentation parameters based on the detected layout type. Different layout clusters receive different segmentation parameter settings, allowing the automated system to adapt to various product presentations (e.g., product-only images vs. product-with-model images) while maintaining high segmentation quality across diverse appearances

Inventive Principle:
Principle #35Parameter changes

2Manufacturing precision

If interactive segmentation methods are used, then segmentation quality is improved, but productivity deteriorates due to manual overhead

Engineering Contradiction:
Improvesegmentation qualityVSAvoidprocessing speed
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The system performs self-service by automatically determining segmentation parameters through layout-based clustering without requiring manual user input. The algorithm autonomously groups images by layout similarity and selects appropriate segmentation strategies for each group, achieving both high quality and high productivity for large-scale image processing

Inventive Principle:
Principle #25Self-service

3Manufacturing precision

If domain-specific appearance models are used, then segmentation quality is improved, but adaptability deteriorates when handling products outside training data

Engineering Contradiction:
Improvesegmentation qualityVSAvoidgeneralization capability
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The system segments the image collection into multiple layout-based clusters, where each cluster represents a different product presentation style. By dividing the diverse set of product images into manageable layout groups, the system can apply appropriate segmentation strategies to each cluster while maintaining the ability to handle novel product appearances through the generalizable layout-based grouping mechanism

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The layout-based clustering approach serves multiple functions: it groups images by visual structure, determines segmentation parameters, and enables generalization to new product types. This universal method works across different product categories and presentation styles without requiring category-specific training data, thereby improving both segmentation quality and adaptability

Inventive Principle:
Principle #6Universality (Multi-functionality)

4Adaptability or versatility

If implicit transductive inference is used, then adaptability is improved, but measurement precision deteriorates for complex layouts

Engineering Contradiction:
Improvescaling capabilityVSAvoidlayout classification accuracy
Core Design Contradiction:
Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The system incorporates feedback mechanisms where segmentation results are evaluated and used to refine layout cluster assignments and parameter selections. This iterative feedback process improves layout classification accuracy for complex layouts while maintaining the adaptability benefits of transductive inference across large image collections

Inventive Principle:
Principle #23Feedback

AI summary

A system for extracting one or more regions of interest from a plurality of images to retrieve images based on visual similarity to a query image. Sequences of image processing associated with a segmentation strategy selected by user are performed on a set of training images to identify the region of interests. The segmentation strategy and the regions of interest are stored, as well as a visual signature of the image that captures the global layout of the image. New images are processed for which no segmentation strategy had previously been defined. A search is made through the layout signatures collected from the set of training images to identify images with similar layouts. Given a query and its visual characteristics, the system finds images stored in the database with visually similar regions of interest.
