More precision in visual search through targeted image sections: segmentation models in e-commerce
Visual search is no longer just a nice add-on, but is increasingly becoming an essential component of modern e-commerce platforms. Customers expect an uncomplicated yet precise way to search for products visually. This is not just about quickly identifying an item, but also about highlighting specific details in the images. This is exactly where segmentation models come into play, taking visual search to the next level.
Why segmentation in visual search?
Traditionally, visual product searches are often based on the entire image. However, this approach has a decisive disadvantage: a photo often contains several products, backgrounds, accessories or decorative elements that are irrelevant for the actual search. This leads to blurred search results or even “false positives”.
With segmentation models, a special application of artificial intelligence (AI) in the field of computer vision, individual objects or specific image areas can be automatically marked and separated from one another. Segmentation enables the user to click directly on an interesting image section and thus refine the search in a targeted manner – without being distracted by irrelevant image elements.
How do segmentation models work?
Segmentation models are based on advanced deep learning architectures that analyze images down to the pixel. The aim is to assign each pixel to a specific class, such as “handbag”, “shoe”, “background” or “decorative element”. The common methods can be divided into three broad categories:
1. Semantic segmentation:
Here, each pixel is assigned a category (class) without distinguishing between individual objects of the same class. Example: All pixels in an image that belong to a shoe are marked as such, but no distinction is made between two similar shoes in the image.
2. Instance segmentation:
This method goes one step further. In addition to identifying the category, each object is recognized individually. For example, two shoes of the same model in the image can be recognized and marked as separate instances. This is particularly interesting if customers want to target a specific example of a product in an image.
3. Panoptic segmentation:
A new approach that combines semantic and instance-based segmentation. All pixels are classified and the individual instances are worked out at the same time. The result is a complete understanding of the image scene.
Practical example: Interactive visual search in e-commerce
Let’s imagine a customer sees various products in a mood image of a fashion campaign: A bag, shoes, a dress and accessories. However, the customer is only interested in the bag. With the help of a segmentation model, the user can simply click on the bag in the image with the cursor. The system automatically recognizes the outline and “segments” the object in order to search for similar products exclusively on the basis of this area.
The result: instead of an imprecise search that also includes clothes, shoes or background objects in the results, the user is only presented with matching, visually similar bags. This leads to an enormous improvement in the user experience – the results are more relevant, the product selection is more accurate and the customer finds what he is looking for more quickly.
Advantages for online retailers
The integration of segmentation models into visual search has many advantages for e-commerce companies:
✓ Higher conversion rate: the improved relevance of search results increases the likelihood that users will discover and purchase their desired product more quickly.
✓ Reduced bounce rates: Frustrating, irrelevant search results are a common reason why customers leave the store. More precise results keep customers on the website for longer.
✓ mproving the customer experience: An intuitive search function that “intelligently” adapts to the user’s needs strengthens trust in the store and increases brand loyalty.
✓ Data-based recommendation management: The information gained from segmentation can also be used for personalized recommendations. Similar products can be suggested precisely based on the detail focused on by the customer.
Technical implementation
In the field, modern deep learning frameworks such as TensorFlow or PyTorch and pre-trained models such as Mask R-CNN, U-Net, SAM or DETR are used. The challenges here lie in the quality of the training data and the performance of the system. A segmentation model must be able to analyze images in real time or at least very quickly in order to guarantee an appealing user experience.
Optimizations such as transfer learning, GPU or TPU acceleration, efficient data transformation pipelines and continuous improvement through active learning processes are helpful here. In addition, e-commerce operators should prepare their catalog images in such a way that the models can be trained as easily as possible. Uniform backgrounds, clear product presentation and high-quality images significantly increase recognition performance.
Conclusion
Segmentation models as a game changer in visual product search
Image segmentation is a real game changer for visual search in e-commerce. Instead of settling for complete image sections, we give users the opportunity to determine for themselves which part of the image should be analyzed. This leads to more relevant recommendations, an improved customer experience and ultimately more sales.
Our company specializes in AI-based e-commerce solutions and supports retailers in integrating innovative visual search features with the help of segmentation models. Together, we create a shopping experience that delights customers and secures competitive advantages in the long term.
