Why is image preprocessing required?

Image preprocessing is required to enhance the quality of input data and ensure consistency for machine learning models. Preprocessing steps like resizing, normalization, and noise reduction improve the model’s ability to learn meaningful patterns. For instance, resizing standardizes image dimensions, while normalization scales pixel values to a uniform range, preventing numerical instability during training. Removing noise and applying filters help focus on relevant features, improving accuracy. Preprocessing ensures that the input data is clean, uniform, and optimized for reliable and efficient model performance.
