Retail marketers connect with customers through powerful images. But creating hyper-relevant, high-quality, on-brand visuals has historically been challenging, primarily because it required an expensive photoshoot for every new initiative.
Latent Bridge Matching (LBM)—a breakthrough innovation by Jasper’s Paris Research Lab—is changing that. LBM is unlocking unprecedented new potential for visual content creation. For retailers, it enables scalable image editing, transforming visuals into reusable, campaign-specific assets personalized for each audience.
Whether it’s relighting a product photo to match a new background, removing unwanted objects from a shot, generating shadows, or restoring degraded images, LBM offers the advanced editing techniques marketers need to produce high-volume, hyper-targeted content without big budgets or time-intensive production efforts.
Let’s take a deeper dive into how LBM is changing visual marketing in retail spaces.
What is latent bridge matching (LBM)?
Latent bridge matching is Jasper’s pioneering technique for rapid, high-fidelity image-to-image translation. Rather than relying on dozens of slow, compute-heavy diffusion steps, LBM completes the transformation in a single step within a compressed latent space, delivering exceptional quality at unmatched speed.
In short: LBM never manipulates raw pixels. It operates on a compact latent representation, precisely mapping source and target distributions in one seamless pass. For instance, the source distribution could be a set of images with poor lighting, and the target distribution could be a set of images with exceptional lighting. LBM will be able to “translate” any poorly lit image into a beautiful, perfectly lit one, as if it were shot in an expensive photo studio.
The key innovation is the use of a stochastic interpolant that models the transition from the original image to the desired result. Think of it as building a bridge between two points—the source and target images—while cutting down on unnecessary steps. This single-step inference approach makes LBM incredibly fast compared to conventional models. LBM is able to edit images in one second instead of 5 seconds. This is a big improvement to the quality of the user experience, and also to reduce the number of GPUs needed to serve the algorithm at scale.
In practice, this means LBM can take an input image, transform it in just one step, and produce a high-quality, realistic output. For retailers, that one-step workflow can relight thousands of furniture shots, for example, or strip backgrounds from an apparel catalog in seconds. It makes keeping pace with seasonal launches and campaign rollouts cost-effective and efficient.
How does it work? The technology behind LBM
What sets latent bridge matching apart isn’t just its speed, but the way it fundamentally rethinks image transformation. Instead of manipulating images directly, LBM works within a compressed representation called latent space.
This approach makes processing faster and guarantees high-quality results without sacrificing image accuracy. Let’s break down how it works:
- Encoding to latent space: The input image is first transformed into a latent representation using a variational autoencoder (VAE). This step compresses the image data while retaining essential features.
- Bridge matching with a stochastic interpolant: The model constructs a bridge between the source and target representations using a stochastic interpolant. This bridge effectively maps how the image should transform from its current state to the desired output.
- Sub-second inference & rapid training: At inference after mapping inputs with the latent encoder, the SDE solver produces the final image in less than a second. In addition to being fast, the full model reliably trains to convergence in just a few hours on standard GPUs—no days-long runs or unstable tuning required.
- Decoding to image space: The latent result is decoded back to the image space, delivering a high-quality output that aligns with the specified transformation.
This architecture is both versatile and robust. By leveraging the power of stochastic modeling within the latent space, LBM outperforms diffusion models that require multiple iterative steps to converge on a result. The combination of precision and speed makes it uniquely suited for real-world marketing applications.
Real-world use cases for marketers
LBM’s capabilities open up a range of exciting possibilities for marketers who rely on compelling visuals to engage their audience. These are some of the most impactful use cases that illustrate how marketers can leverage this technology to elevate their content strategy.
1. Dynamic product relighting
Marketers often need product images that maintain the same high quality under different lighting conditions. LBM makes this easy by allowing rapid relighting of products to match diverse environments, whether that’s outdoor sunlight or a sleek studio setup. With just one inference step, marketers can update lighting without the need for reshooting or manual editing.
2. Realistic shadow generation
Shadows add depth and realism to product photos. LBM generates controllable shadows that accurately reflect the lighting conditions of the scene. This makes product images look authentic and professional. The precision of shadow generation means marketers can adapt images to various contexts without sacrificing quality or realism.
3. Image restoration and enhancement
LBM can breathe new life into old, degraded, or low-quality images. It can restore details and adjust lighting to make visuals look polished and fresh without requiring time-consuming manual edits. This is particularly valuable for brands looking to repurpose archival content or enhance user-generated images.
4. Object removal
Sometimes, an otherwise perfect shot is ruined by an unwanted element like a stray object, a distracting background detail, or a misplaced prop. LBM can seamlessly remove these types of intrusions while preserving the natural look of the image.
LBM in the future
Latent bridge matching offers a new way of approaching visual content creation. As brands push for richer and more dynamic storytelling, the demand for fast, scalable, and high-quality visual transformations will only grow. LBM meets this need head-on, helping marketers craft compelling content without compromising on speed or precision.
As LBM gains traction, we’ll likely see new creative possibilities emerge, from real-time visual customization to more adaptive and context-aware marketing assets. This is just the beginning of how Jasper AI’s innovative vision will help shape the next generation of marketing visuals.
