Comparison of performance between the fully affine invariant group and the CLAHE-based conventional group. A, The CLAHE adjusted FOV image of each session from A5 (upper row) and A6 (lower row). CLAHE, contrast limited adaptive histogram equalization. The correlation between $ROI{s}_{Mask}{\hspace{0.17em}}_{template}^{common}$ and the registered $ROI{s}_{Mask}{\hspace{0.17em}}_n^{common},n\in \left(S08,S09,S10,S11,S12,S16,S17\right)$ of different methods for area A5 (B) and A6 (C). The correlation coefficients of the fully affine invariant group and the unregistered pairs of $\left\{ROI{s}_{Mask}{\hspace{0.17em}}_n^{common},ROI{s}_{Mask}{\hspace{0.17em}}_{template}^{common}\right\}$ are represented by black dashed lines and black solid lines, respectively. The results of LK-CLAHE, ECC-CLAHE, MOCO-CLAHE, TurboReg-CLAHE, and NoRMCorre-CLAHE were shown in dark red, dashed gray, purple, dashed yellow, and blue color, respectively.
