This is similar to issue #18095. ## Affected Code ```cpp MORPH_OPEN = 2, //!< \f[\texttt{dst} = \mathrm{open} ( \texttt{src} , \texttt{element} )...\f] MORPH_CLOSE = 3, //!< \f[\texttt{dst} = \mathrm{close} ( \texttt{src} , \texttt{element} )...\f] MORPH_GRADIENT = 4, //!< \f[\texttt{dst} = \mathrm{morph\_grad} ( \texttt{src} , \texttt{element} )...\f] MORPH_TOPHAT = 5, //!< \f[\texttt{dst} = \mathrm{tophat} ( \texttt{src} , \texttt{element} )...\f] MORPH_BLACKHAT = 6, //!< \f[\texttt{dst} = \mathrm{blackhat} ( \texttt{src} , \texttt{element} )...\f] ``` ## Expected `\texttt{element}` should be `\texttt{kernel}` to match the `morphologyEx()` function signature: ```cpp CV_EXPORTS_W void morphologyEx( InputArray src, OutputArray dst, int op, InputArray kernel, ...); ``` I'll take this issue.
