  • Its performance exceeds that of other well-known computer vision and image processing libraries, including OpenCV, to deliver typical speeds 11X and 7X faster than that of OpenCV on GPUs and CPUs respectively.
  • Along with this, you filter photographs and draw contour lines on them.
  • They support displaying attributes as a standalone image and as an overlay layer on the original image.
  • In Aurora Vision Library careful design of algorithms goes hand in hand with extensive
    hardware optimizations, resulting in performance that puts the library among the fastest in the world.
  • To understand why, just imagine each image as a large matrix of dots, each of which has its own set of attributes, including color, size, and position in relation to the surrounding dots.
  • Optimized VPI algorithms include background subtraction, perspective warp, temporal noise reduction, histogram equalization, and lens distortion.

As an extension of a PyTorch library, TorchVision contains the most common image transformations for computer vision. It also contains datasets and model architectures for computer vision neural networks. One of the main goals of TorchVision is to provide a natural way of using computer vision image transformations with PyTorch models without converting them into a NumPy array and back.

Deploy ready-to-use, domain-specific, high-performance functions for image, video, and signal processing. Deploy the trained model to hardware to monitor and detect the next time Fido leaves the house using an installed camera. Detection involves locating and localizing an object or multiple objects within an image or a video frame.

The solution is to use unsupervised deep learning mode that
detects any significant variations from what the tool has seen and
learned in the training phase. Typical
applications require between 20 and 50 images for training. The more the
better, but our software internally learns key characteristics from a
limited training set and then generates thousands of new artificial
samples for effective training. The documentation includes a guide through library design, architecture, installation process, examples, and API reference. The library contains attribute methods at the level of the entire model, at the level of a single layer, and the deep feature factorization method.
