This would save a few function calls.\r\n\r\nIf we are computing in the frequency domain we are recomputing fourier transforms of data unnecessarily. I suspect this is not the case.\r\n\r\nIf we are in spatial domain, it is possible that some \"housekeeping\" tasks are being repeated unnecessarily for each new feature map, e.g. if implemented by partitioning data then this is being done repeatedly. Note the dot prod calculations would remain same.\r\n"},"comment":{"url":"https://api.github.com/repos/jfrancis71/Machine-Vision/issues/comments/152143993","html_url":"https://github.com/jfrancis71/Machine-Vision/issues/9#issuecomment-152143993","issue_url":"https://api.github.com/repos/jfrancis71/Machine-Vision/issues/9","id":152143993,"user":{"login":"jfrancis71","id":8302110,"avatar_url":"https://avatars.githubusercontent.com/u/8302110?v=3","gravatar_id":"","url":"https://api.github.com/users/jfrancis71","html_url":"https://github.com/jfrancis71","followers_url":"https://api.github.com/users/jfrancis71/followers","following_url":"https://api.github.com/users/jfrancis71/following{/other_user}","gists_url":"https://api.github.com/users/jfrancis71/gists{/gist_id}","starred_url":"https://api.github.com/users/jfrancis71/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/jfrancis71/subscriptions","organizations_url":"https://api.github.com/users/jfrancis71/orgs","repos_url":"https://api.github.com/users/jfrancis71/repos","events_url":"https://api.github.com/users/jfrancis71/events{/privacy}","received_events_url":"https://api.github.com/users/jfrancis71/received_events","type":"User","site_admin":false},"created_at":"2015-10-29T10:44:16Z","updated_at":"2015-10-29T10:44:16Z","body":"Possible interesting paper on frequency domain convolution:\r\nhttp://bmvc2015.swansea.ac.uk/proceedings/papers/paper160/paper160.pdf"}}
