CV-CUDA Python Package
CV-CUDA is an open-source library of GPU-accelerated computer vision algorithms designed for speed and scalability. It delivers high-throughput, low-latency image/video processing for AI pipelines across NVIDIA cloud, desktop, and edge platforms. CV-CUDA is built for performance and works seamlessly with C/C++ and Python frameworks.
For more information on available operators, API documentation, and getting started guides, refer to our online documentation.
Installation
pip install cvcuda-cu13
CV-CUDA in action
Fully GPU-accelerated image resizing with nvImageCodec and CV-CUDA.
import cvcuda
from nvidia import nvimgcodec
# Decode image directly to GPU
decoder = nvimgcodec.Decoder()
image = decoder.read("input.jpg")
# Convert to CV-CUDA tensor and process
cvcuda_tensor = cvcuda.as_tensor(image, "HWC")
resized = cvcuda.resize(cvcuda_tensor, (224, 224, 3), cvcuda.Interp.LINEAR)
