What algorithm is used for object recognition?
Popular algorithms used to perform object detection include convolutional neural networks (R-CNN, Region-Based Convolutional Neural Networks), Fast R-CNN, and YOLO (You Only Look Once). The R-CNNs are in the R-CNN family, while YOLO is part of the single-shot detector family.
What algorithm does OpenCV use for object detection?
Haar cascade:
Basically, the Haar cascade technique is an approach based on machine learning where we use a lot of positive and negative images to train the classifier to classify between the images. Haar cascade classifiers are considered as the effective way to do object detection with the OpenCV library.
What is the most accurate object detection algorithm?
Name | Best for | mAP (Accuracy) |
YOLO | Real-time object tracking | 57.9% |
EfficientDet | Mobile and embedded devices | 54.3% |
RetinaNet | Security systems | 57.5% |
Faster R-CNN | Detailed image analysis | 60-70% |
