Area of Science:

Computer Vision
Food Science
Quality Control

Background:

Automated quality detection in food processing is crucial for safety and efficiency.
Traditional methods often struggle with complex visual tasks like defect identification in processed foods.
Frozen food production requires robust image segmentation for accurate quality assessment.

Purpose of the Study:

To develop an advanced image segmentation algorithm for detecting defects in frozen stuffed food.
To improve the accuracy and efficiency of quality control in food production lines.
To introduce an Optimized Small Neighborhood Clustering (OSNC) algorithm for enhanced food quality detection.

Main Methods:

Feature vectors were constructed using image attribute parameters.
A small neighborhood clustering algorithm was employed for image segmentation based on sample feature vectors.
Optimal segmentation parameters, including sampling rate and points, were determined using a search method and validity judgment function.

Main Results:

The Optimized Small Neighborhood Clustering (OSNC) algorithm achieved a defect detection accuracy of 95.9%.
OSNC demonstrated superior anti-interference capabilities compared to existing segmentation algorithms.
The algorithm exhibited faster segmentation speeds and better preservation of essential image information.

Conclusions:

The OSNC algorithm effectively addresses limitations of current image segmentation techniques in food quality detection.
This method significantly improves the qualified rate of food quality in frozen food processing.
OSNC offers a promising solution for automated, high-accuracy defect detection in the food industry.
