    Study Notes

    Object Detection Fundamentals

    • The standard approach to object detection involves identifying the location and class of objects within an image.

    Classification in Object Detection

    • The focus of classification in object detection is to determine the class or category of the object, rather than just its presence or absence.

    Classification vs Detection

    • The main difference between classification and detection is that classification involves assigning a single label to an entire image, whereas detection involves locating and classifying objects within an image.

    Region-Based CNNs

    • The method that implements object detection using region-based CNNs is referred to as Faster R-CNN (Region-based Convolutional Neural Networks).

    Design Issues and Trade-Offs

    • Building object detection methods involves design issues and trade-offs, such as:
      • Balancing accuracy and speed
      • Choosing between precision and recall
      • Handling class imbalance and occlusion
      • Addressing computational resources and memory constraints
