OpenCV Error: cv2.minMaxLoc Unsupported Data Type (23) - Solution Guide

The error message "cv2.minMaxLoc src data type = 23 is not supported" suggests that the source data type used in the cv2.minMaxLoc function is not supported. In OpenCV, the cv2.minMaxLoc function is used to find the minimum and maximum values and their locations in an image. However, it is important to note that this function supports only certain data types, such as 8-bit unsigned integers (CV_8U), 32-bit floating-point numbers (CV_32F), and 64-bit floating-point numbers (CV_64F). Data type 23 is not one of the supported types, hence the error message. To resolve this issue, you need to ensure that the source data type used in the cv2.minMaxLoc function is one of the supported types.
