Case Study

Challenge Safe autonomous vehicle navigation depends on the detailed annotation of road features like lane lines, road edges, and curbs and the ability of onboard mapping models to adapt to real-time road conditions and changes, like temporary lane lines or changes in road layout. The challenge lies in annotating road features in camera images using splines and polylines—annotations that underlie the base dataset for onboard mapping models. The better the annotations, the better the models can adapt to those changing conditions, which is why our client needed a workforce trained in precision spline annotations. DDD’s Solution DDD tackled the challenge by developing a specialized team of 50 annotators to annotate lane lines and road edges. We adopted new quality metrics, including points per line length, line continuity, and F1 scoring. In an ongoing engagement spanning more than two years, we now label more than 100,000 lines monthly and maintain more than 96% quality across all metrics. Empowering real-time road analyses through advanced spline annotation. Impact The precision and reliability of our team’s spline annotation work allowed our client to complete a successful test in the first city and expand into several others. The expansion speaks to our client’s confidence in our ability to deliver reliable, accurate data. Thanks to the DDD team, our client’s cloud-driven mapping model seamlessly adapts and makes real-time adjustments based on road changes

Challenge Although one of the more straightforward LiDAR data processing tasks, object boxing is still challenging. For applications like ADAS, the task requires extreme precision. Mislabeling or inaccuracies in object detection can lead to faulty interpretations and safety risks. Scaling LIDAR data annotation is another challenge, calling for a large workforce with specialized skills and advanced training. Further, while scaling is underway, labeling quality must also stay consistent. Faced with the daunting task of finding a team capable of meeting such stringent need our client turned to DDD. DDD’s Solution DDD performed extremely well and rapidly scaled the team from 20 to 1,000+ annotators in just a few months, providing comprehensive training on the client’s platform so our team could use LiDAR and camera images to make determinations. We leveraged an annotator / reviewer process to exceed 98% quality (F1 and IOU adherence). By expanding the team, we now process more than 10,000K scenes per year, showcasing our ability to scale without compromising annotation quality. Mastering object boxing for enhanced object tracking Impact DDD’s proficiency in LiDAR object boxing enhanced the precision of our client’s object detection capabilities, making its autonomous driving systems safer and more reliable. Today, those systems can identify and respond to a broader range of road objects, reducing the risk of accidents and improving autonomous vehicle safety.

Challenge For autonomous vehicles to navigate safely, models must recognize standard road features and rare objects—emergency vehicles, animals, roadblocks, and unusual pedestrian scenarios, such as a person in a wheelchair. These rare objects cause problems because they appear infrequently but complicate the road environment. Our client needed its dataset to include rare objects, but labeling them called for a sophisticated ontology and a team skilled in rare object annotation. DDD’s Solution We quickly scaled up a team of 50 annotators and led them through an intensive multi-week training program to familiarize them with an extensive ontology of hundreds of rare objects. Today, our team processes 50K+ images each month, of which approximately 20K are rare objects. Given that rare objects appear infrequently and their nature varies depending on geography and environment, we chose an inter-annotator agreement approach to ensure consistency and accuracy in labeling. Excelling in complex ontology and precision annotation for enhanced vehicle safety. Impact The result is 99.5% quality in identifying scenes with rare objects and 98% label accuracy. The precision and reliability of our team’s spline annotation work allowed our client to complete a successful test in the first city and expand into several others. The expansion speaks to our client’s confidence in our ability to deliver reliable, accurate data. Our client’s cloud-driven mapping model seamlessly adapts and makes real-time adjustments based on road changes.

Challenge Our Agtech client relied on visible signs to spot plant diseases, due to which, yields were lost, and treatments were less effective. Their crop protection practices sprayed entire fields, wasting resources, increasing costs, and harming the environment. A smarter solution was needed to detect problems early, before symptoms appeared, and to use robotics and precision spraying to intervene only where it was truly needed. DDD’s Solution At Digital Divide Data (DDD), we produced high-quality annotated images across diverse crops, marking diseased areas and tiny insects that threatened plant health. Each annotation became vital training data that helped AI detect issues earlier and guide smarter interventions. Our HITL-based Agtech model training allowed spotting of crops before symptoms were visible, guided robots to only affected areas, reduced chemical costs, mapped harmful insects, and enabled stronger, more scalable agtech models. “Driving higher yields with smarter and sustainable farming solutions.” Impact The work we did for this customer goes beyond annotation; it laid the foundation for a smarter, more resilient agricultural ecosystem. By building precise, large-scale datasets, we made it possible to: ● Auto-annotate crop images with accuracy, reducing the reliance on manual labor. ● Lower operational costs by automating scouting and monitoring tasks. ● Apply crop protection with pinpoint precision, minimizing costs and environmental impact. ● Adapt solutions across different crops and regions, making the technology globally relevant. ● Protect food security by detecting problems earlier and reducing both yield losses and post-harvest waste.  

Challenge A leading autonomous vehicle manufacturer sought to enhance the safety and accuracy of its Advanced Driver Assistance Systems (ADAS). Their existing perception models, responsible for object detection, lane keeping, and pedestrian recognition, were underperforming in complex urban and highway environments. The core issue stemmed from insufficiently labeled training data, particularly across varying camera perspectives, sensor modalities, and lighting conditions.

Cost Efficiency: By leveraging DDD’s hybrid delivery model, the client achieved a 30% reduction in per-frame annotation cost compared to in-house operations. The collaboration accelerated the client’s ADAS product release timeline and also set a new standard for data quality governance and process transparency in large-scale 2D/3D annotation programs.

Challenge Our client needed a highly skilled and rapidly scalable annotation team capable of segmenting and labeling massive LiDAR datasets with exceptional precision to ensure safe and reliable ADAS performance. They required a workforce that could maintain strict accuracy standards to prevent safety-critical misinterpretations, scale quickly to manage large and complex data volumes, and undergo specialized training to deliver consistent, high-quality annotations across all projects. DDD’s Solution DDD met these requirements by rapidly expanding its LiDAR segmentation team from 20 to over 500 trained annotators within just a few months, fully onboarded to the client’s platform. Led by experienced team leads and trainers, we have consistently labeled more than 10,000K scenes annually for over two years. Through our robust annotator-reviewer workflow, we’ve maintained over 97% per-object quality (F1/IOU), ensuring precision, consistency, and reliability at scale. Impact By rapidly expanding and training a specialized workforce, we have provided consistent, high-quality data labeling for over two years, powering model accuracy, reliability for product verification, and safety case. This ongoing collaboration showcases DDD’s capability to manage large, complex annotation pipelines while meeting stringent performance and quality benchmarks.

Challenge A leading enterprise faced significant obstacles with their large language models LLMs). The models frequently produced hallucinations, biased outputs, and incomplete responses, making them unreliable for real-world deployment. Internally, the client’s team wanted to prioritize scaling and training their core LLMs rather than diverting resources to prompt design, dataset creation, and benchmarking. They needed a partner with both technical expertise and domain knowledge to reduce errors, enforce safety guardrails, and align outputs with their business context. DDD’s Solution Digital Divide Data (DDD) deployed its Human-in-the-Loop Fine-Tuning services to address these challenges. Our subject matter experts curated task-specific datasets, ensuring they were accurate, privacy-safe, and aligned with the client’s industry needs. Using Supervised Fine-Tuning (SFT), we adapted strong base models to perform with greater precision and compliance. Our team also implemented prompt engineering strategies and scenario-based benchmarking to validate model improvements at each stage. Through red teaming and adversarial testing, we identified safety risks and biases, hardening the models against harmful outputs and ensuring consistent, context-aware responses. Impact We delivered a comprehensive set of prompts and responses crafted in the proper syntax and style for each domain, ensuring factual accuracy and alignment with the client’s context. These resources gave the client a structured way to verify, train, and tune their LLMs, streamlining the validation process and reducing the burden on internal teams. As a result, the models produced fewer hallucinations and biased outputs, while delivering more accurate, context-aware, and user-aligned responses. This translated into stronger model performance and a noticeably improved user experience.

Challenge A client working with large language models (LLMs) faced critical limitations in accuracy and trustworthiness. Their models often produced irrelevant, biased, or fabricated outputs, creating barriers to scaling into production. They needed a partner who could deliver domain-specific, structured training resources that would directly improve model quality and reduce risks. DDD’s Solution Digital Divide Data (DDD) applied its human-in-the-loop fine-tuning methodology to address these gaps. Our subject matter experts designed domain-aware prompts across the client’s areas of focus and paired them with fact-checked, context-rich responses. These were carefully structured into multiple task categories, including summarization, extraction, closed-form Q&A, ensuring the LLM could be tuned to handle both simple and complex workflows. In addition, DDD provided a framework for systematic validation and benchmarking, giving the client a clear process to measure improvements over time. Impact With these curated datasets and structured benchmarks, the client achieved more reliable, safer, and context-aware outputs from their LLMs. Hallucinations and biased responses were significantly reduced, while overall alignment with user intent improved. The combination of improved model performance and operational efficiency translated into a stronger user experience and accelerated path to eployment.
