What are some common tools used for computer vision?

Computer vision (CV) uses a mix of **image-processing libraries, machine-learning frameworks, pretrained models, and annotation tools**. Some of the most common are: - **OpenCV** - A general-purpose computer vision library for image/video processing, feature detection, object tracking, camera calibration, and more. It supports Python, C++, Java, and other languages. [About - OpenCV](https://opencv.org/about/?utm_source=chatgpt.com) - **PyTorch + Torchvision** - Widely used for training and deploying deep-learning vision models. Torchvision provides datasets, image transformations, pretrained models, object detection, segmentation, keypoint detection, and optical-flow functionality. [torchvision - Torchvision 0.28 documentation](https://docs.pytorch.org/vision/stable/?utm_source=chatgpt.com) - **TensorFlow + Keras/KerasCV** - Another major deep-learning ecosystem. It provides tools for image classification, object detection, segmentation, augmentation, and image preprocessing. [Computer vision with TensorFlow | TensorFlow Core](https://www.tensorflow.org/tutorials/images?utm_source=chatgpt.com) - **scikit-image** - A Python library focused on traditional image processing, such as filtering, edge detection, segmentation, morphology, and image transformations. [scikit-image: Image processing in Python - scikit-image](https://scikit-image.org/index.html?utm_source=chatgpt.com) - **Pillow (PIL)** - Useful for basic image loading, resizing, cropping, format conversion, and manipulation; it is also commonly used alongside deep-learning libraries. - **NumPy** - Frequently used underneath CV pipelines to represent and manipulate images as multidimensional arrays. - **YOLO** - A family of real-time object-detection models commonly used to identify and locate objects in images and video. - **ONNX** - A model format/ecosystem that helps move trained models between different machine-learning frameworks and inference environments. - **Labeling/annotation tools** - Tools such as Label Studio and CVAT are used to create bounding boxes, segmentation masks, keypoints, and other training labels. ### A typical CV stack For example, an object-detection project might use: **OpenCV → image/video capture and preprocessing** **NumPy → numerical image manipulation** **PyTorch/Torchvision → model training** **YOLO or another detector → object detection** **CVAT/Label Studio → training-data annotation** If you're **just starting with computer vision**, I'd recommend learning **Python + NumPy + OpenCV**, then adding **PyTorch/Torchvision** for deep learning.
