The correct choice is Object detection. It both finds where animals appear in each photo and assigns labels to each instance so EcoVision Labs can automatically tag and organize the large trail-camera image library without human review.

Object detection models analyze image regions and return category labels along with bounding box coordinates for every detected instance which supports counting animals and creating searchable metadata for the dataset.

Named entity recognition works on text to extract people and place names and other entities so it cannot locate or label animals in images.

Image inpainting restores or fills missing or corrupted pixels so it is used for image repair rather than detecting or labeling objects.

Anomaly detection highlights unusual or outlier samples which can flag rare images but it does not provide per-object labels or locations needed to identify animals in photos.
