What technique should be used to identify the location of a bear within a photo?

1. Optical character recognition (OCR)

2. Image classification

3. Object detection

4. Semantic segmentation

The correct answer is: Object detection

Object detection is the appropriate technique for identifying the location of a bear within a photo because it not only recognizes the presence of an object (in this case, the bear) but also provides the specific location within the image by bounding boxes. This method is designed to locate and classify multiple objects in an image, which is essential when you need to pinpoint the exact area where the object appears. In contrast, image classification would only provide a label for the entire image rather than identifying locations of specific objects within it. Optical character recognition focuses on detecting and converting text within images, which is irrelevant for identifying animals. Semantic segmentation divides the image into segments, classifying pixels into different categories, but does not create bounding boxes or explicitly highlight objects' locations, making it less suitable for this specific task.
