CV_FM_8POINT for an 8-point algorithm. N≥8
CV_FM_RANSAC for the RANSAC algorithm. N≥8
CV_FM_LMEDS for the LMedS algorithm. N≥8

but parameters should be:
FM_7POINT for a 7-point algorithm. N=7
FM_8POINT for an 8-point algorithm. N≥8
FM_RANSAC for the RANSAC algorithm. N≥8
FM_LMEDS for the LMedS algorithm. N≥8

System information (version)

• OpenCV => 4.5.0-dev

Detailed description

Docs could be further described as un-descriptive. If anyone has links or description for the different methods I could include them in the fix.
