Step-by-step explanation:
Search images are achieved by visually identifying what safe-to-eat food looks like. The visual appeal of food, such as color and appearance, is an important factor in determining its safety. When determining if food is safe to eat, we often rely on visual cues. For example, fresh fruits and vegetables should appear vibrant and free from blemishes. If a food item appears spoiled, discolored, or has an off smell, it is an indication that it may not be safe to consume.
For instance, if you are looking at a tomato, you would expect it to have a bright red color and smooth skin. If the tomato is discolored, mushy, or has mold, it is a sign that it is not safe to eat. By visually assessing these characteristics, we can determine if the food is safe to consume.
