@brief Computes the Enhanced Correlation Coefficient (ECC) value between two images @brief Computes the Enhanced Correlation Coefficient (ECC) value between two images
The Enhanced Correlation Coefficient (ECC) is a normalized measure of similarity between two images. The Enhanced Correlation Coefficient (ECC) is a normalized measure of similarity between two images @cite EP08.
The result lies in the range [-1, 1], where 1 corresponds to perfect similarity (modulo affine shift and scale), The result lies in the range [-1, 1], where 1 corresponds to perfect similarity (modulo affine shift and scale),
0 indicates no correlation, and -1 indicates perfect negative correlation. 0 indicates no correlation, and -1 indicates perfect negative correlation.
