Revolutionizing Image Search: Introducing Zero-shot Composed Image Retrieval for Enhanced Precision and Versatility

As Seen On

In recent years, the significance of image retrieval has cemented its place in the digital landscape, marking a considerable shift in the way we search and interpret content online. Predominantly, text-based search engines reigned supreme, but they tend to falter in the context of complex items such as fashion apparel where a picture is worth a thousand words. Enter Composed Image Retrieval (CIR), an innovative approach that intelligently amalgamates the power of image and text to retrieve the most accurate and desired items.

CIR has rapidly gained traction for its instrumental service in aiding users to retrieve complex items meticulously, enhancing the user’s experience and interaction with search engines. However, as captivating as it may be, it isn’t devoid of hitches. An enormous downside lies in the critical necessity for labeled data, the accumulation of which can be expensive and challenging, especially in extensive quantities. Additionally, conventional CIR methodologies are frequently optimized for specialized use cases, attenuating their efficiency when grappling with different datasets. Consequently, it opens a new avenue to introduce a more versatile, cost-effective solution – Zero-shot Composed Image Retrieval (ZS-CIR).

Unlike its predecessor, ZS-CIR doesn’t necessitate labeled triplet data but brilliantly functions across a spectrum of tasks, including object composition, attribute editing, or domain conversion. The collection of large-scale image-caption pairs and unlabeled images becomes an effortless chore, enhancing its adaptability.

Taking the lead in pioneering advances for ZS-CIR is the proposed task ‘Pic2Word’, which ingeniously maps pictures to words. Herein, a retrieval model is trained, harnessing large-scale image-caption pairs and unlabeled images. Additionally, the code for this task has been made available, fostering a collaborative environment to stimulate progress in this domain.

Diving into the methodological overview, the contrastive language-image pre-trained model (CLIP) plays a cardinal role, particularly via its Language Encoder. A standout feature is a lightweight mapping sub-module nested within CLIP, engineered to map an input picture from the image embedding space to a word token in the textual input space. Through rigorous optimization, the model’s network is tuned to ensure a close alignment between the visual and text embedding spaces. Ultimately, this advanced system treats the query image as a word, enabling a flexible and seamless composition, bringing the future of image search into the present.

In summary, the revolutionary Zero-shot Composed Image Retrieval not only improves the precision in retrieving complex images but stands as a beacon for future advancements in image search engines. By eliminating the need for labeled triplet data and introducing a flexible model with varying applications, ZS-CIR heralds an era where image search is no longer confined by the limitations of text-based tools. Undoubtedly, the realm of image retrieval just got a whole lot more versatile and efficient.

Up until working with Casey, we had only had poor to mediocre experiences outsourcing work to agencies. Casey & the team at CJ&CO are the exception to the rule.

Communication was beyond great, his understanding of our vision was phenomenal, and instead of needing babysitting like the other agencies we worked with, he was not only completely dependable but also gave us sound suggestions on how to get better results, at the risk of us not needing him for the initial job we requested (absolute gem).

This has truly been the first time we worked with someone outside of our business that quickly grasped our vision, and that I could completely forget about and would still deliver above expectations.

I honestly can't wait to work in many more projects together!
