Ideas in this flowchart

• Computer-vision systems prepare images before performing a task.
• Image preprocessing may occur before the task.
• The system may resize the image.
• The system may correct the image’s color representation.
• The system may remove noise from the image.
• The system may extract features from the image.
• Modern deep-learning models can learn useful features directly from training data.
• Preprocessing and calibration may still be important.
