From Training to Real-Time Inference: How to Solve Computer Vision Challenges in Healthcare | Wallaroo.AI blog

Implementing CV in healthcare involves significant challenges during the inference phase—when models are used to make predictions on new data. These challenges are crucial to address to ensure CV models are effective and reliable in clinical settings. Wallaroo.AI unified inference platform is  a powerful solution to address these challenges, providing high-performance real-time inference at scale.

Inference Difficulties in Computer Vision for Healthcare

Implementing CV in healthcare involves significant challenges during the inference phase—when models are used to make predictions on new data.  In this phase, the models are used to make predictions on new data, which is crucial for accurate diagnoses and treatment recommendations. However, there are several obstacles that need to be addressed to ensure the success of CV models in clinical settings.

Low Latency Requirements

In critical healthcare applications, such as emergency diagnostics and surgical assistance, CV models must provide real-time or near-real-time predictions. High latency can delay decision-making, adversely affecting patient outcomes.

Solutions:

  • Model Optimization: Techniques such as quantization and pruning can reduce model size and improve inference speed.
  • Hardware Acceleration: Utilizing specialized hardware like GPUs, TPUs, or FPGAs to accelerate inference tasks. For edge deployments, devices like NVIDIA Jetson or Google Coral can provide the needed computational power.
  • Efficient Data Pipelines: Designing efficient data preprocessing and input pipelines to minimize overhead and latency.

Computational Constraints

Real-time inference often requires substantial computational resources, which can be limited in edge devices or older hospital IT infrastructure.

Solutions:

  • Edge and Cloud Hybrid Deployment: Implementing a hybrid architecture that balances tasks between edge devices (for low latency) and cloud (for higher computational power).
  • Resource Optimization: Using containerization and orchestration tools like Docker and Kubernetes to efficiently manage and allocate computational resources.

Model Generalization and Robustness

Variability in Data

Medical images can vary widely due to differences in imaging equipment, protocols, and patient demographics. CV models must generalize well across diverse datasets to be effective in real-world scenarios.

Solutions:

  • Data Augmentation: Applying extensive data augmentation techniques during training to simulate variability and improve model robustness.
  • Domain Adaptation: Employing domain adaptation techniques to ensure models generalize well across different imaging modalities and settings.

Handling Noise and Artifacts

Medical images can contain noise and artifacts that affect the accuracy of CV models. Ensuring models are robust to such variations is essential for reliable inference.

Solutions:

  • Adversarial Training: Incorporating adversarial examples during training to enhance model robustness against noise and artifacts.
  • Continuous Validation: Regularly validating CV models against new and diverse datasets to maintain robustness.

Scalability and Infrastructure

Scalable Inference Pipelines

Deploying CV models at scale requires robust infrastructure to handle high volumes of image data and concurrent inference requests, which can strain hospital IT systems.

Solutions:

  • Microservices Architecture: Using a microservices approach to deploy different components of the CV pipeline, enabling independent scaling and maintenance.
  • Autoscaling: Implementing autoscaling features to dynamically adjust resources based on demand.

Edge and Cloud Deployment

Balancing the trade-offs between edge (on-device) and cloud-based inference is crucial. Edge deployment offers low latency but limited computational power, while cloud-based solutions provide greater power but introduce latency and dependency on network connectivity.

Solutions:

  • Hybrid Deployment Strategies: Leveraging both edge and cloud resources to optimize performance and scalability.
  • Efficient Packaging: Quickly and efficiently packaging models and ML pipelines for edge deployment at scale.

Interpretability and Trust

Explainable AI

Clinicians need to understand the rationale behind CV model predictions to trust and act on them. Developing interpretable models that provide clear explanations for their outputs is critical.

Solutions:

  • Model Explainability Tools: Integrating tools such as LIME, SHAP, or Grad-CAM to provide visual and textual explanations for model predictions, helping clinicians understand and trust the outputs.
  • Iterative Feedback Loop: Establishing a feedback loop with clinicians to continuously improve model performance and interpretability based on real-world usage and feedback.

Integration with Clinical Workflows

CV models must seamlessly integrate into existing clinical workflows without adding complexity or requiring significant changes in how clinicians operate.

Solutions:

  • User-Centric Design: Collaborating with healthcare professionals to design user interfaces and integration points that align with clinical workflows, ensuring minimal disruption and ease of use.
  • Comprehensive MLOps Platform: Using a unified MLOps platform like Wallaroo.AI that supports deployment, serving, monitoring, and optimization of CV models to ensure smooth integration and operation.
