Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems face challenges in identifying and processing noisy samples, such as document images and user-generated content, due to variations like noise, resolution changes, and unauthorized copyrighted content, which hinder effective comparison and classification.
Innovation Solution
A system that minimizes noise-induced variance by generalizing samples and exemplars using a moving average filter, allowing for effective comparison and identification of document types and copyrighted content, and contextualizing noisy samples to facilitate processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If direct content comparison techniques are used to identify copyrighted content in user-generated content, then the identification process is straightforward, but noise from variations (resolution, sampling rate, unauthorized content) renders the technique ineffective
Solution Approach 1:
The patent segments the content comparison process into multiple stages: initial direct comparison, noise detection, selective filtering of variations, and iterative refinement. This segmentation allows the system to handle different types of noise (resolution, sampling rate, unauthorized content) at appropriate stages rather than attempting single-pass comparison.
Solution Approach 2:
The system performs preliminary actions by pre-processing user-generated content to detect and flag variations before comparison. It prepares reference content with expected variation patterns and pre-establishes filtering criteria, enabling more accurate subsequent comparisons despite noise.
2Productivity
If pixel and location checking techniques are used to compare document images with templates, then the comparison process is simple, but noise from user additions (handwritten information, stamps, annotations) renders the technique ineffective
Solution Approach 1:
The patent applies local quality by treating different regions of the document image differently. It identifies stable regions (form fields, printed text) versus variable regions (handwritten areas, stamp locations) and applies appropriate comparison strategies to each, allowing automated processing of stable regions while flagging variable regions for selective handling.
Solution Approach 2:
The system dynamically adjusts its comparison approach based on detected content types. It transitions from rigid pixel-matching for printed regions to more flexible pattern recognition and contextual analysis for handwritten or annotated regions, maintaining productivity while accommodating noise.
3Reliability
If variations in user-generated content are allowed to maintain original quality, then the content authenticity is preserved, but the variations prevent correct identification of copyrighted content
Solution Approach 1:
The patent introduces an intermediary processing layer that mediates between preserving original content quality and enabling accurate identification. This intermediary system creates transformed representations of both reference and user-generated content that normalize variations while maintaining essential content characteristics, allowing accurate comparison without degrading original authenticity.
Solution Approach 2:
The system changes comparison parameters dynamically - adjusting resolution tolerance, sampling rate thresholds, and similarity criteria based on the type of variation detected. This allows the system to maintain sensitivity to authentic content while becoming tolerant of expected variations in resolution and sampling.
4Measurement precision
If manual identification and classification of received forms is performed, then accurate classification is achieved, but the processing time and labor costs increase significantly
Solution Approach 1:
The patent applies partial action by performing automated comparison and classification only for portions of forms that are stable and machine-readable. It processes high-confidence regions automatically while flagging ambiguous regions for manual review, achieving high overall accuracy without requiring complete manual processing of every form.
Solution Approach 2:
The system incorporates feedback mechanisms where manual corrections and classifications are fed back into the system to refine its comparison algorithms and update reference templates. This continuous learning improves automated classification accuracy over time, reducing the proportion of forms requiring manual processing.

AI summary
A system for contextualizing noisy samples by substantially minimizing noise induced variance may include a memory, an interface, and a processor. The memory is operative to store exemplars. The processor is operative to receive, via the interface, a sample which includes exemplar content corresponding to one of the exemplars, and noise. Variance induced by the noise may differentiate the sample from one or more of the exemplars. The processor may generalize the sample and the exemplars in order to substantially minimize the variance. The processor may compare the generalized sample to the generalized exemplars to identify the exemplar corresponding to the exemplar content of the sample. The processor may contextualize the sample based on a document type of the identified exemplar. The processor may present the contextualized sample to a user to facilitate interpretation thereof, and in response thereto, receive data representative of a user determination associated with the noise.
