Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The process of selecting suitable somatic embryos for germination in conifer tissue culture is labor-intensive and prone to subjective errors, as it relies on visual evaluation of morphological features, which can be clone-specific and difficult to automate, especially when dealing with large-scale production of millions of plants.
Innovation Solution
The use of near-infrared (NIR) imaging systems and methods to classify plant embryos by developing classification models based on reflectance spectral data acquired from multiple positions along the embryo, allowing for the differentiation of embryo types and suitability for germination through wavelength-by-position analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If visual evaluation methods are used to select somatic embryos for germination, then subjective assessment of morphological features can be performed, but the process becomes labor-intensive and time-consuming
Solution Approach 1:
The patent replaces the manual visual evaluation system with an automated image analysis system using machine vision and computer algorithms. The system captures images of somatic embryos and automatically analyzes morphological features such as axial symmetry, cotyledon development, surface texture, and color, eliminating the need for manual inspection while maintaining assessment accuracy.
Solution Approach 2:
The patent creates digital copies (images) of the somatic embryos and performs analysis on these copies rather than examining the physical embryos directly. This allows multiple measurements and analyses to be performed on the digital representations without handling or disturbing the actual embryos, significantly reducing time and labor while preserving measurement precision.
2Reliability
If manual selection of somatic embryos is performed, then skilled evaluation can be applied, but it poses a major production bottleneck for large-scale plant production
Solution Approach 1:
The patent replaces the human expert evaluation system with an automated image analysis system that uses computer vision and pattern recognition algorithms. The system reliably assesses morphological features consistent with expert judgment while operating continuously at high speed, thereby maintaining selection reliability while eliminating the production bottleneck caused by manual processing limitations.
Solution Approach 2:
The patent transforms the selection process from manual visual assessment to automated digital image analysis, changing the fundamental parameters of the system. The image analysis system processes multiple embryos simultaneously and can evaluate numerous morphological parameters objectively, increasing productivity while maintaining or improving reliability through consistent application of evaluation criteria.
3Extent of automation
If instrumental image analysis is used to replace visual evaluation, then automation can be achieved, but considerable pre-judgment of morphological features and development of mathematical extraction methods are required
Solution Approach 1:
The patent develops a universal image analysis system that can evaluate multiple morphological features (axial symmetry, cotyledon development, surface texture, color) using a single integrated platform. The system uses general-purpose image processing algorithms that can be applied to various somatic embryo types, reducing the need for separate specialized systems while achieving high automation.
Solution Approach 2:
The patent implements an image analysis system that automatically identifies and extracts relevant morphological features without requiring extensive manual pre-programming of feature selection. The system self-adjusts to identify important characteristics based on the images provided, reducing the complexity of setup and adaptation while maintaining high automation levels.
4Quantity of substance
If traditional image analysis methods are used, then size and shape information can be extracted, but relatively little information from the image is actually utilized
Solution Approach 1:
The patent moves beyond traditional two-dimensional image analysis by incorporating spectral imaging in the near-infrared region. This adds a spectral dimension to the analysis, allowing extraction of chemical and physiological information from the embryos that is not visible in standard images. The system analyzes reflectance spectra at multiple wavelengths, dramatically increasing the volume of information extracted from each embryo image.
Solution Approach 2:
The patent changes the analysis parameters from basic geometric measurements to comprehensive spectral analysis. By examining reflectance properties across multiple near-infrared wavelengths, the system extracts detailed information about embryo composition, development stage, and germination potential, significantly increasing the quantity and quality of information obtained while maintaining processing efficiency through automated spectral analysis.
