Would GPUImage framework allow me to do High-pass filter? If not can I do High pass filter using some other filter provided by ur framework Thanks for advises

Brad Larson's GPUImage framework, which this is based off of, did have a high-pass filter implemented that I have yet to port over. If you are looking for a simple sharpening filter, SharpenFilter.java will work. If you are looking for a high-pass filter for the difference between two video frames (which is what Brad Larson's GPUImage framework high-pass filter is doing) or you need a true high-pass filter, it is possible to do it with this framework, but it has not been written yet.

Thank you for your response. I have a function that removes the skin blemishes are developing. High-pass filter is a very, very important resource. I get help if you are willing to pay (using PayPal)

Do you have an email address where you can contact us directly?

If you are just trying to apply a inverted high-pass filter to a masked area and real-time image processing is not imperative, I would recommend looking into OpenCV and/or its java counter part (JavaCV). It has been ported to android and it does have a high-pass filter already implemented. If you have any further questions, I can be reached at cwbatt@gmail.com

Hello, thanks for your great framework.

I would like to use LowPassFilter and HighPassFilter. Would you please let me know how to get them?

Thanks!
