MarsSeed [1] filed a deletion request for perl-image-objectdetect [2]: Broken Perl module, abandoned by upstream since 2010 (14 years ago). [a] Has been reported failing to build 12 years ago. [b] And it cannot be built now as well. It seems it is no longer compatible with the current opencv library.
