29. Object Detection Using Machine Learning
• ImageAI library
• Tensorflow based
• Need Image Model Library
detector = ObjectDetection()
detector.setModelTypeAsRetinaNet()
detector.setModelPath( os.path.join(execution_path , "resnet50_coco_best_v2.0.1.h5"))
detector.loadModel()
detections = detector.detectObjectsFromImage(input_image=os.path.join(execution_path , "berwickontweed.jpg"),
output_image_path=os.path.join(execution_path , "resnet.jpg"))
resnet=plt.imread('resnet.jpg')

50. Train Your Model
Precision: How often Model’s
predictions were correct. In this case
1/6 is a false positive
Recall: How often model found
known objects. 1/6 is a missed
prediction.
