Images become numerical arrays that encode pixels or other representations. A model learns patterns useful for its objective, but those patterns can include accidental correlations. A classifier may rely on a background rather than the object a developer intended it to recognize. Define the output precisely. Classification assigns labels to an image; detection locates object instances; segmentation labels pixels or regions. A model that identifies an object category may still fail to locate its boundary or distinguish several overlapping instances. Evaluate on realistic cameras, lighting, resolutions, viewpoints, and environments. Keep related images from the same scene or recording together when splitting data to avoid overly optimistic results. Inspect uncommon conditions and the cost of different mistakes. The application must also handle image quality, permissions, uncertainty, and downstream actions. A confident label is not proof that a scene is safe or that an inferred attribute is appropriate to use. Preserve the source image and meaningful review information when people need to check a result.
