+# PR Summary: Enhanced OpenCV CUDA Build with GitHub Workflow
+
+## Overview
+
+This PR creates a new GitHub workflow and updates the OpenCV build process based on improvements identified in the super-resolution functionality (similar to PR #198) and incorporates the enhanced build script from the updated documentation.
+
+## Changes Made
+
+### 1. New GitHub Workflow (`.github/workflows/opencv-cuda-build.yaml`)
+
+- **Docker-based automated building** using `livepeer/comfyui-base` as foundation
+- **Artifact generation** for distribution and deployment
+- **Configurable parameters** for OpenCV version and CUDA architecture
+- **Self-hosted GPU runner** support for optimal build environment
+- **Release automation** for tagged versions
+
+#### Key Features:
+- **Dockerfile-based builds** for better maintainability
+- Triggers on changes to build-related files
+- Manual dispatch with customizable options
+- Produces downloadable artifacts with 30-day retention
+- Creates GitHub releases for tagged versions
+- **Modular script architecture** separated from workflow logic
+- Comprehensive build verification
+
+### 2. Docker-based Build System
+
+#### New Dockerfile (`docker/Dockerfile.opencv-cuda`)
+- **Uses `livepeer/comfyui-base`** as the foundation image
+- **Modular script execution** for better maintainability
+- **Configurable build arguments** for OpenCV version and CUDA architecture
+- **Multi-stage verification** throughout the build process
+
+#### Modular Build Scripts
+1. **`scripts/opencv-cuda-deps.sh`** - Comprehensive dependency installation
+2. **`scripts/opencv-build.sh`** - Core OpenCV compilation (updated from documentation)
+3. **`scripts/opencv-package.sh`** - Artifact creation with installation script
+
+#### Improvements from Documentation:
+- Updated to OpenCV 4.11.0 by default
+- **Modular architecture** instead of monolithic scripts
+- Better handling of CUDA architectures
+- Improved library path management
+- Enhanced error handling and verification
+- **Docker layer optimization** for faster rebuilds
+
+### 3. Enhanced Entrypoint Script (`docker/entrypoint.sh`)
+
+Updated the existing OpenCV installation process to:
+
+- **Attempt prebuilt download first** (maintaining backward compatibility)
+- **Fallback to source build** using the new script if download fails
+- **Better error handling** and user feedback
+- **Automatic verification** of installation success
+- **Flexible package location detection**
+
+## Connection to Previous Work
+
+This builds upon the super-resolution support added in commit `9ff4b39` (which appears to be related to PR #198) by:
+
+1. **Improving the build process** that was initially introduced for super-resolution functionality
+2. **Adding automation** through GitHub workflows to generate reliable artifacts
+3. **Incorporating best practices** from the updated documentation
+4. **Maintaining backward compatibility** with existing systems
+
+## Benefits
+
+### For Development:
+- **Reliable builds** through automated workflows
+- **Consistent artifacts** across different environments
+- **Easier testing** of OpenCV CUDA functionality
+- **Better debugging** with comprehensive logging
+
+### For Deployment:
+- **Faster installation** with prebuilt artifacts
+- **Fallback mechanism** ensures installation always succeeds
+- **Verification steps** confirm CUDA functionality
+- **Easy distribution** through GitHub releases
+
+### For Super-Resolution Nodes:
+- **Enhanced performance** with optimized OpenCV builds
+- **Better CUDA utilization** through updated architecture support
+- **Improved reliability** with verified installations
+- **Easier troubleshooting** with better error messages
+
+## Verification
+
+The workflow includes automatic verification that:
+- OpenCV compiles successfully with CUDA support
+- Python can import cv2 module
+- CUDA device count is detected correctly
+- All required libraries are properly linked
+
+## Backward Compatibility
+
+All changes maintain full backward compatibility:
+- Existing Docker builds continue to work unchanged
+- Current installation paths are preserved
+- Fallback mechanisms ensure no breaking changes
+- API remains identical for end users
+
+## Files Changed
+
+- ✅ `.github/workflows/opencv-cuda-build.yaml` (new)
+- ✅ `docker/Dockerfile.opencv-cuda` (new)
+- ✅ `scripts/opencv-cuda-deps.sh` (new)
+- ✅ `scripts/opencv-build.sh` (new)
+- ✅ `scripts/opencv-package.sh` (new)
+- ✅ `docker/entrypoint.sh` (updated)
+- ✅ `docs/opencv-cuda-build.md` (new documentation)
+
+## Testing
+
+The workflow can be tested by:
+1. Triggering manual dispatch from GitHub Actions
+2. Making a test commit to trigger automatic build
+3. Verifying artifacts are generated correctly
+4. Testing installation in a clean environment
+
+This enhancement significantly improves the reliability and maintainability of the OpenCV CUDA build process while providing better automation and distribution mechanisms.
