Despite its significant advancements, computer vision continues to face several challenges that hinder its widespread adoption and effectiveness. One of the primary obstacles is data quality and annotation. High-quality labeled datasets are crucial for training AI models, yet they are expensive and time-consuming to create. Many computer vision applications require extensive datasets to achieve high accuracy, but issues such as bias in the data, poor labeling, and lack of diversity can lead to unreliable results. Ensuring that training datasets are comprehensive and representative of real-world scenarios remains a major concern, as biased models can produce inaccurate predictions and reinforce existing disparities in applications like facial recognition and medical diagnostics.

Another challenge is generalization across domains. Computer vision models often struggle when applied to environments different from those in which they were trained. Factors such as lighting conditions, background changes, and object variations can significantly impact model performance. For instance, an AI system trained on urban road images may fail to recognize objects in rural settings. Researchers are continuously working on improving domain adaptation techniques and developing more robust architectures that can perform consistently across diverse conditions without requiring extensive retraining. The ability to generalize well across different contexts is essential for deploying computer vision systems in dynamic real-world applications, such as autonomous driving and industrial automation.

Real-time processing is another significant hurdle, particularly for applications that require instant decision-making, such as robotics, video surveillance, and augmented reality.
