Hi Scott san, Thank you for your comment and clarification.
In that sense, would JIRA be the better place to gather pieces of information for discussion? I have a few more ideas of enhancement for 2D input; local inhibition, boosting,... ,etc. (from software perspective) Best Regards, 2013/8/14 Scott Purdy <[email protected]> > You are correct that a separate scalar encoder for each pixel would not be > a good method.
