Currently, labeling of various enzymes was the mainly strategy for signal amplification, unfavorably, this method usually suffered inferior stability.
Non-destructive methods usually suffer from uncertainty factors, but may provide global information on subsurface damage distribution.
Despite the progresses in tongue body segmentation, the existing methods usually suffer from some limitations and cannot meet the performance requirements of a practical computational tongue diagnosis system.
And traditional active and passive cooling methods usually suffer from the disadvantages of external energy consumption, uneven temperature distribution and low thermal conductivity of phase change materials (PCMs).
The bottom-up methods usually suffer from complex processes, or expensive starting materials and severe synthetic conditions, which are unlikely to be extended significantly in the near future [23].
Conventional localization methods usually suffer from different limitations, such as low accuracy and blind areas for Global Positioning System (GPS), high cost for Inertial Navigation System (INS), and low robustness for vision Simultaneously Localization and Mapping (vSLAM).
However, these methods usually suffer from either destructive molding operations or cell loss and non-uniform cell distribution among the wells due to two-step molding and cell seeding.
In Fig. 11, the first image is of non-uniform blur with slight roll rotations, from which one can see that GAC can achieve more visually plausible deblurring results, such as the statue's face is recovered more clearly, while the uniform deblurring methods usually suffer from ringing artifacts.
In addition, large-scale experimental methods usually suffer from high rates of both false positives and false negatives [ 12, 15– 20].
Water injection, the most commonly used method of IOR, usually suffers from reduced efficiency due to reservoir heterogeneity and increased cost associated with water recycling and handling.
