Which processing is performed after image data has been stored?

• A. Postprocessing
• B. Preprocessing
• C. Memory
• D. Thresholding

Answer: (A)

Postprocessing is the stage that applies after image data has been stored. Once the data is saved, you perform operations to enhance quality, reveal details, or extract useful information—things like adjusting contrast, filtering, sharpening, noise reduction, segmentation, or feature extraction. Preprocessing happens before analysis or storage to prepare the data, such as correcting acquisition artifacts or aligning images. Memory refers to storage, not processing. Thresholding is a specific technique that can be used within postprocessing, but the general category described here is postprocessing.
