Using drones to identify the growth of weeds in crop fields is an example of which type of computer vision?

1. Facial recognition

2. Image classification

3. Object detection

4. Optical character recognition (OCR)

The correct answer is: Object detection

Using drones to identify the growth of weeds in crop fields exemplifies object detection in computer vision. Object detection is a process that involves identifying and locating objects within an image or video. In this context, the goal is to differentiate between crops and weeds, which means the system must not only recognize these entities but also determine their locations within the field as captured by the drone's cameras. This process enables farmers to monitor weed infestation accurately and make informed decisions regarding the application of herbicides, leading to more efficient and sustainable agricultural practices. The technology can analyze visual data from the drone, identify multiple types of plants, and provide insights into their sizes and distributions across the landscape. In contrast, the other types of computer vision mentioned are not applicable here. Facial recognition focuses specifically on identifying human faces; image classification involves categorizing images into predefined classes without locating specific instances; and optical character recognition (OCR) deals with recognizing and converting different types of text into readable formats. These definitions illustrate why the correct choice is indeed object detection, as it encompasses the essential elements required to address the task of identifying and locating weeds in crop fields.
