Computer vision, a branch of AI, enables machines to interpret and understand visual information just like humans do but faster and with higher capacity. Computer vision models can recognize objects, detect and track people, and analyze images and videos, this greatly expands the area of possible automation. Computer vision development services is a rapidly growing field that has the potential to revolutionize various industries. 

As retail becomes increasingly data-driven, the demand for computer vision technology is growing. Gartner identifies computer vision as the only AI-based technology that is months away from its peak productivity and is ready for wide-range adoption. Surprisingly, only 4% of retailers [1] are currently using computer vision in retail, despite the fact that most of them have expressed a strong interest in integrating it into their business operations.

Computer vision provides many advantages and is currently not well-represented in the market. Given the maturity of the technology and the significant benefits it brings, it is an excellent opportunity to gain competitive advantages. 

Let’s explore the applications, benefits, and prospects of computer vision in retail.

In-store computer vision 

Until 15 years ago, people were irreplaceable for anything related to visual comprehension. With computer vision, more processes can become fully automated and thus perfected. Delegating tasks from employees to specialized algorithms almost always improves productivity by optimizing processes, reducing errors, cutting costs, and enabling humans to concentrate on higher-value tasks. Here is a list of use cases of computer vision in retail that are looking to transform the industry: 

Cashierless checkout

One of the most remarkable and innovative uses of computer vision in the retail industry is cashierless checkout. When customers are faced with a frustratingly long queue due to the slow nature of the checkout process, it can considerably affect their shopping experience and lead them to abandon their purchase. Extended waiting times harm the store's reputation and cause customers to seek out alternative shopping locations.

Chashierless checkout technologies enable customers to shop and pay for their items without the need for traditional checkout processes or cashiers. It uses computer vision algorithms to track and identify products selected by a customer as they shop. It allows customers to simply pick up the items they want and then automatically charges their account as they leave the store, eliminating the need for physical cashiers, checkout lines, or self-checkout machines.

Retail giants like Amazon and Aldi have already embraced cashierless checkout technology. Amazon Go and Amazon Fresh convenience stores leverage computer vision in retail to offer a seamless shopping experience, while Aldi has piloted its Shop&Go checkout-free concept in selected stores. 

Loss prevention and security

Shoplifting has been a persistent issue for all retailers, which has been particularly distressing in the last five years. According to the BRC Crime Survey, £953M ($1.2B) was lost to shoplifting in the UK in 2022. Many businesses have recognized the need for an effective way to prevent thieves from leaving the store. Computer vision is one powerful technology that can greatly enhance store security.

Computer vision-based security systems use the same technology as cashierless checkout systems to link a customer to their shopping cart. Unlike a human security guard who can get distracted, a vision system does not face such problems and stays alert 24/7. These systems can identify suspicious behaviors and detect potential theft or fraud incidents. When combined with cashierless checkout, it becomes impossible to take advantage of a distracted guard and shoplift.

Another way this technology aids loss prevention is the detection of sweethearting, a technique where cashiers intentionally fail to scan products or manipulate prices. Sweathearting can also be directed at oneself as self-checkout stations are mostly based on trust which leads to millions in losses for the business. Computer vision systems recognize every item in the checkout area, correlate it with the transaction, identify instances of sweethearting, and prevent employee theft.

Computer vision systems can also detect unusual crowd movements, unauthorized access, and other security breaches. These proactive security measures enhance store safety and protect both customers and employees. This is particularly important for retailers whose greatest security concerns are not limited to shoplifting. 

Collecting analytics 

Computer vision technology, through the analysis of visual data, offers valuable insights into customer behavior and helps retailers improve customers’ experience. By integrating AI algorithms with the production environment, retailers can track customer movements and gain real-time insights into customer interactions with products and displays. The type of clear and easily available information that was previously collected only online can also be available for physical outlets. 

Heat map technology, which utilizes real-time movement detection and assigns colors based on traffic volume, plays a crucial role in visualizing customer behavior and making data-driven decisions about store layouts. Previously, retailers could only make educated guesses about these analytics. With data at hand, retailers can make data-driven decisions to optimize store layouts, improve product placement, and enhance the overall shopping experience for their customers.

Another thing that computer vision in retail can provide insight into is the demand for staff and the optimal shift assignments. Without real data on the peak hours and customer’s need for assistance, this would have to be decided in the dark.

Understanding customer behavior and analyzing shopping patterns are also fundamental for retailers looking to improve their operations and marketing strategies. They offer valuable information for measuring the effectiveness of marketing campaigns, assessing store layout performance, and identifying areas for improvement. Retailers can also use this data to understand peak shopping times, optimize staffing levels, and allocate resources more effectively, ultimately leading to an enhanced customer experience and increased overall sales.

Quality control

In retail, especially when dealing with fashion, electronics, or any products with visual characteristics, maintaining quality is crucial. Computer vision can be employed for visual inspection of products at manufacturing, distribution, and in-store.

Computer vision algorithms detect defects or imperfections in products. They compare the product to a standard and check if it meets design criteria, including size, color, and quality standards. Ensuring that products meet quality standards consistently leads to higher customer satisfaction, lower return rates, and increased trust in the brand.

Computer vision in inventory management

Maintaining optimal inventory levels is crucial for retailers to meet customer demand and maximize sales. Computer vision technology integrated with inventory management systems allows retailers to analyze visual data from cameras mounted on shelves, detecting low inventory levels and notifying store staff when action is needed. 

This approach enables retailers to provide a seamless shopping experience and avoid missed sales opportunities. By automating the inventory management process, retailers can streamline replenishment procedures and ensure that popular products are always available to customers.

Let’s look at how N-iX has implemented a computer vision solution coupled with a modernization of a warehouse management system to see how this technology can benefit businesses in practice.
