J joneden Active Member Licensed User Longtime User May 2, 2014 #1 Hi All, I'm converting an application that I have for Windows to run on an industrial PC running Android. I have used Aforge to take the webcam input and do some analysis looking for blobs of specific colours. Now I need to do this on Android. Is anyone aware of any library that will look at an image and then indicate if there is the presence of a certain colour. The analysis would need to work for the colour +/- a certain range and also to have a minimum blob size to ensure that single pixel detection doesn't fire an affirmative hit. I'm hoping that there is something out there as I dread having to write my own code for this! Thanks in advance for any pointers. Regards Jon

J joneden Active Member Licensed User Longtime User May 6, 2014 #3 Hi Erel, Yes was wanting to do it in real time. My main issue is that I have potentially multiple colours that I am watching out for so have to check one at a time. I'm thinking at the moment that I need to look into the OpenCV Java code and strip that back for my purposes. Assuming that no better solutions are available. Regards Jon Upvote 0
