Mixed quality of algorithms but all in all becoming a de facto standard **Rating:** 3.0/5.0 stars **Reviewed by:** Verified User in Industrial Automation | Enterprise (> 1000 emp.) **Reviewed Date:** December 12, 2017 **What do you like best about OpenCV?** A lot of high quality algorithms are available and due to the vast amount of users, it's easy to get help and find information, e.g. on stackoverflow **What do you dislike about OpenCV?** The quality and style of the included algorithms varies quite a lot depending on original author. A more uniform "look and feel" and stricter rules about documentation for accepted algorithms would be appreciated. **What problems is OpenCV solving and how is that benefiting you?** Image filters, fourier transformation, SIFT ### 2. Open Cv **Rating:** 3.0/5.0 stars **Reviewed by:** Verified User in E-Learning | Small-Business (50 or fewer emp.) **Reviewed Date:** December 12, 2017 **What do you like best about OpenCV?** the new feature of dynamic dispatching is good, also it can now be built as C++ 11 library using the flag ENABLE_CXX11. Provides good support for basic shape detection e.g Circle,rectangle etc.The relative upgrade in OpenCV helps speed improvement in our core & imgproc perf tests. **What do you dislike about OpenCV?** For images where lighting condition are not very good it may not work perfectly. POC for Text recognition ,result use to vary as per the picture quality and lighting condition. **What problems is OpenCV solving and how is that benefiting you?** As of it surely contributes to the project based needs. ## OpenCV Discussions - [What is OpenCV used for?](https://www.g2.com/discussions/opencv-what-is-opencv-used-for) - 1 comment - [What algorithm does OpenCV use?](https://www.g2.com/discussions/what-algorithm-does-opencv-use) - 1 comment - [View OpenCV pricing details and edition comparison](https://www.g2.com/products/opencv/reviews?filters%5Bnps_score%5D%5B%5D=3§ion=pricing&secure%5Bexpires_at%5D=2026-08-12+17%3A45%3A20+-0500&secure%5Bsession_id%5D=119dba9f-ba11-44ed-aa72-c983580e0655&secure%5Btoken%5D=f45520f9bb6170501429dfe8c09018b2655160141036ce911a41426024dff557&format=llm_user) ## OpenCV Features **Additional Functionality** - Tagging - Natural Language Processing - Data Extraction - Multi-Language - Predictive Analytics - Drag & Drop - Speech Recognition - Reporting/Analytics - Data Storage Management - Virtual Personal Assistant (VPA) - AI Copilot - Customer Segmentation - Collaboration Tools - Data Import/Export - Generative AI - For eCommerce - Role-Based Permissions - Customizable Branding - Search/Filter - Monitoring - Document Management - API - Data Visualization - Trend Analysis - Machine Learning - Access Controls/Permissions - Alerts/Escalation - Performance Metrics - Real-Time Data - Third-Party Integrations - Mobile App - Multiple Data Sources - For Sales Teams/Organizations - Sentiment Analysis - Activity Dashboard - Chatbot - Workflow Automation **Additional Functionality** - No-Code - Search/Filter - Data Import/Export - Data Visualization - Activity Dashboard - Workflow Management - Quality Control - Third-Party Integrations - Model Training - Multi-Language - Data Profiling - Visualization - Data Capture and Transfer - Predictive Analytics - Performance Metrics - Image Recognition - Version Control - Neural Network Modeling - Generative AI - Synchronous Learning - Natural Language Processing - Monitoring - Data Transformation - Customizable Reports - Voice Recognition - Performance Management - Compliance Management - Troubleshooting - Content Management - Asynchronous Learning - Real-Time Reporting - API - Artificial Neural Networks - AI Copilot - ML Algorithm Library - Real-Time Data - Collaboration Tools - Self-paced Learning - Data Extraction - Configuration Management - Data Security - Visual Analytics - Activity Tracking - Continuous Delivery - Document Classification - Image Analysis - Progress Tracking - Reporting & Statistics - Real-Time Monitoring **Recognition Type** - Emotion Detection - Object Detection - Text Detection - Motion Analysis - Scene Reconstruction - Logo Detection - Explicit Content Detection - Video Detection - Multiple Data Sources - Analytics **Facial Recognition** - Facial Analysis - Face Comparison **Labeling** - Model Training - Bounding Boxes - Custom Image Detection - Reverse Image Search **Deployment** - Integrations **Additional Functionality** - Image Classification - Image Segmentation - Generative AI - Optical Character Recognition - Barcode Recognition - Catalog Management - Workflow Management - Natural Language Processing - Data Management - Video Search - Text Extraction - Content Import/Export - Facial Recognition - API - Product Search - Product Recommendations - Automated Image & Video Editing - Dashboard - AI Copilot - Image Query - Pose Estimation - Image Tagging - Annotations - Intellectual Property Protection - Photo Capture - AI/Machine Learning - Mobile App - Data Retrieval - Search/Filter - Image Recognition - Customer Activity Tracking ## Top OpenCV Alternatives - [Google Cloud Vision API](https://www.g2.com/products/google-cloud-vision-api/reviews) - 4.4/5.0 (98 reviews) - [Microsoft Computer Vision API](https://www.g2.com/products/microsoft-computer-vision-api/reviews) - 4.1/5.0 (49 reviews) - [Amazon Rekognition](https://www.g2.com/products/amazon-rekognition/reviews) - 4.3/5.0 (28 reviews)
