Question 88

Which computer vision task identifies the exact location of objects within an image?

A) Object detection
B) Image classification
C) OCR
D) Semantic segmentation

Answer: A) Object detection

Explanation:

Object detection is a core technique within computer vision that focuses on identifying and locating objects within an image. Unlike simpler image analysis methods, object detection not only recognizes what objects are present but also determines their precise positions by drawing bounding boxes around each detected item. This dual functionality—classification combined with localization—makes object detection a powerful tool for applications that require understanding both the presence and spatial context of objects within visual data. Its ability to provide detailed information about multiple objects in a single image differentiates it from other computer vision techniques, which may focus solely on recognition or textual extraction.

For instance, image classification is another widely used computer vision method, but it operates differently. Instead of identifying where objects are in an image, image classification assigns a single label to the entire image based on the predominant content. While this approach is effective for categorizing images into broad classes—such as labeling an image as “cat” or “dog”—it lacks the spatial awareness provided by object detection. Image classification does not indicate the number of objects or their locations, making it unsuitable for applications where precise positioning is critical.

Optical Character Recognition, or OCR, is another computer vision technique, but its purpose is different. OCR focuses on reading and extracting text from images, such as scanned documents, invoices, or street signs. While OCR is highly effective at converting printed or handwritten text into machine-readable formats, it does not provide information about the objects themselves or their positions within the visual scene.

Semantic segmentation offers a more granular approach compared to object detection. Instead of just drawing bounding boxes, semantic segmentation assigns a label to every pixel in an image. This allows for detailed understanding of object shapes, boundaries, and overlapping regions. While semantic segmentation provides greater precision, it also requires more computational resources and complexity to implement, and it may be overkill for applications that only need object locations and classifications rather than full pixel-level detail.

Object detection has practical applications across a wide range of industries. In retail, it is used to track inventory, analyze shelf arrangements, and monitor customer behavior. In security, object detection supports surveillance systems by identifying potential threats or intruders in real time. Autonomous vehicles rely heavily on object detection to recognize pedestrians, vehicles, road signs, and obstacles, enabling safe navigation in dynamic environments. Its versatility, efficiency, and ability to combine recognition with localization make object detection a critical technology for modern AI-driven solutions that require a comprehensive understanding of visual scenes.

object detection is a specialized computer vision technique that identifies objects and determines their positions within an image using bounding boxes. Unlike image classification, which labels entire images, OCR, which extracts text, or semantic segmentation, which provides pixel-level detail, object detection balances precision and efficiency. Its applications span retail, security, and autonomous systems, making it an essential tool for interpreting and interacting with visual data in real-world scenarios.

Explainable AI techniques, interpretable models, and clear documentation help stakeholders understand the logic behind AI-driven outcomes. Transparency not only fosters trust but also enables accountability by allowing organizations to demonstrate compliance with regulatory standards and ethical guidelines.

Accountability ensures that individuals or organizations remain responsible for the AI systems they create and deploy. This includes monitoring system behavior, responding to errors, and taking corrective action when unintended consequences occur. Establishing clear lines of responsibility and governance frameworks is essential to prevent misuse and maintain public confidence in AI technologies.

Safety and reliability are also fundamental to Responsible AI. Systems must operate robustly under a variety of conditions, minimizing risks of harmful or unexpected behavior. This requires rigorous testing, validation, and continuous monitoring of deployed models to ensure consistent performance. Privacy protection is closely tied to safety, as AI systems often process sensitive personal data. Responsible AI mandates adherence to data protection regulations, secure storage, and ethical handling of personal information to safeguard user privacy.

It is important to distinguish Responsible AI from standard machine learning tasks. Techniques such as clustering, which groups similar items; classification, which predicts categorical outcomes; and regression, which predicts numerical values, focus on analyzing data and generating predictions. While these methods are essential to AI functionality, they do not inherently address the ethical, social, or legal considerations associated with deploying AI systems. Responsible AI complements these technical approaches by embedding principles of fairness, transparency, accountability, safety, and privacy throughout the AI lifecycle.

Responsible AI is a critical framework that ensures AI technologies are trustworthy, ethical, and compliant with societal expectations.
