Gray-level mapping is also called what
WebCT Definition: (Merills) Process of creating a cross-sectional tomographic plane of any part of the body. CT Definition: (Bontragers) CT uses a complex computer and mechanical imaging system to provide sectional anatomic images in the axial, sagittal and coronal planes. A patient is scanned by an x-ray tube ____ around the body part being examined. WebExplanation: In general, grey-level slicing includes the following two types of approaches: The first one includes assigning all grey levels of a specific range high value and a low value to all other grey levels. However, the second approach not only brightens the relevant grey-level pixel value but also preserves the background.

The notational … WebIt also advocates the use of turbo codes and LDPC codes in BICM together with Gray mapping to approach the Shannon limit of the underlying constellation. Numerical results based on turbo codes [72] and irregular LDPC codes [65] actually exhibit near-Shannon limit performance as in the case of binary signaling, and verify this view.
