In recent years, the integration of Machine Vision Systems (MVS) has brought about a new era of efficiency and quality assurance in the food business. This article explores the many uses of MVS in food identification, highlighting its historical development, examining real-world applications, and envisioning potential future developments. 

The exploration of real-world applications of MVS in the food industry highlights examples where these systems enhance speed, accuracy, and safety in food processing - such as the FEROX Project. This article aims to provide a clear picture of the present situation and promising future developments for machine vision systems in the food industry. 

The Evolution of machine vision systems

The capability of machine vision systems has advanced significantly since its inception. MVS has evolved from simple image processing to a complex artificial intelligence subset able to perform detailed visual analysis.  

The initial stages saw the creation of the basic algorithms that established the opportunity for further developments in food identification. These discoveries made it possible to incorporate machine vision into the complex process of food manufacturing, where accuracy and precision are crucial. 

Today, its applications in a variety of sectors, particularly food technology, are setting new standards of accuracy and dependability. MVS applications have an immediate impact on the agriculture industry.  

MVS are playing an important function in crop monitoring, disease detection, and yield prediction when paired with advanced algorithms. This integration makes precision agriculture attainable, allowing farmers to make data-driven decisions for efficient crop management. 

Current Food Detection Applications 

1. Quality Control and Inspection

In the agricultural sector, ensuring the quality of products is essential - especially food products. MVS excels in this area by carrying out thorough quality control checks. It can identify flaws such as discolouration, odd shapes, or foreign particles, guaranteeing that only items that meet the highest standards reach customers. 

MVS are increasing their influence on agriculture beyond traditional quality control by revolutionising crop assessment and monitoring. Advanced systems may analyse crop health and quality using comprehensive picture analysis, resulting in more informed agricultural operations. 

2. Sorting and Grading 

Another important use of MVS is the automated sorting and grading of food items. These devices improve efficiency and reduce mistakes associated with human inspections by analysing criteria such as size, colour, and texture. 

MVS has grown their capabilities in the agricultural area to automated sorting and grading of harvested crops. The technique enables the classification of fruits and vegetables based on size, maturity, and quality, simplifying post-harvest operations and optimising agricultural produce distribution. 

3. Detection of Contaminants 

One of the main objectives of utilising MVS for agricultural food detection is ensuring the safety of food products. MVS equipped with powerful algorithms that detect pollutants quickly, assisting in the manufacturing of safer food products. This ability is critical in fulfilling regulatory requirements and establishing customer confidence. 

By extending its reach into the field of agriculture, MVS helps identify plant illnesses and crop contamination early on. The technology detects crop health irregularities using high-resolution images and powerful algorithms, allowing for quick action to prevent extensive harm. 

4. Agriculture Using 3D Machine Vision 

The opportunities created by MVS are further enhanced by the incorporation of 3D Machine Vision in agriculture. Farmers can now evaluate and manage crops more precisely and effectively because of this technology, which automates the whole growth process from planting to harvesting.  

The use of multiple dimensions improves the accuracy of activities like planting, watering, and harvesting. Consequently, this accuracy results in higher yields and more efficient use of resources. 

Revolutionising Food Detection with FEROX Machine Learning 

The goal of the FEROX project is to assist labourers who gather wild berries and mushrooms in secluded and wild regions of the Nordic nations. The project's solution will make use of the most recent developments in robotics, data, and artificial intelligence (AI) technology.  

There is a great demand for a solution that enhances the human experience. Access to wild berries and mushrooms is quite difficult since they grow in woods. The plucking is often done manually by enthusiasts and foreign labourers. 

It calls for both physical stamina and endurance in the summer's variable weather. Furthermore, some of the foreign workers may have anxiety about becoming injured or lost in the forests, since they are unfamiliar with the work environments and the local language. 

The Objectives of the Ferox Project 

The Ferox project has several objectives. Most notably, in terms of applying Machine Vision System in food detection: 

1. The creation of a novel solution built on the combination of artificial intelligence, computer vision, and drones to monitor harvesting operations, enhance berry pickers' working conditions, and reduce risks and threats to their safety while doing so. 

2. Verify the engineering and design methods in two stages, concentrating on (i) physical assistance and logistics optimisation; and (ii) monitoring, navigation, and locating.  

3. Evaluate the impact of the FEROX use cases on workers, measuring improvements in workers' health, considering first aid and anomaly detection times. 

The project also aims to train machine vision systems to detect and categorise plant types utilising above-canopy pictures, including hyperspectral images and point clouds. Furthermore, FEROX will divide aerial photos into areas that are most likely to have berries in them. In order to identify the kind of vegetation that is best for the growth of berries and mushrooms, deep learning classification models will be trained for berry detection. 

The detections produced by each of the machine vision models will be combined to create a distinct and integrated model representation. Agricultural leaders and workers will be able to forecast the growth and yield of berries and mushrooms by using such models.  

Additionally, new data can be added to the models on an ongoing basis. Both the identification of individual berries and a general estimation of the quantity of berries will be provided by AI. 

 Final Thoughts on Machine Vision System in Food Detection 

The application of Machine Vision Systems is revolutionising the food industry, particularly in the sectors of food processing and identification. In order to enable their current in-depth visual analysis, MVS first developed from simple image processing to a complex subset of artificial intelligence.  

This development resulted in the possibility of its implementation into food production, where accuracy is an essential element. Nowadays, MVS is essential to agriculture for yield prediction, disease detection, and crop monitoring, supporting precision farming and knowledgeable crop management. 

Quality control and inspection, where MVS finds product faults and guarantees that only high-standard items reach customers, are key uses of MVS in food detection. It also improves agricultural operations by revolutionising crop evaluation and monitoring.  

The FEROX project, which aims to improve the collection of wild berries and mushrooms in Nordic nations, is a significant accomplishment in this industry. This initiative aims to enhance the safety and working conditions for harvesters by utilising drones, computer vision, and artificial intelligence.  

FEROX is dedicated to developing solutions for effective monitoring and navigation, logistics optimisation, and onsite assistance. In addition, the project uses aerial photos to train machine vision systems for the identification and classification of different plant types.  

 
This helps estimate the development and harvest of berries and mushrooms. By combining these models, berry and mushroom farming may be better understood, leading to improved agricultural methods and insights. 

The application of Machine Vision Systems has the potential to revolutionise the food business even more as it develops, enhancing global food security and promoting sustainable practices in food detection.
