Is there a way to repeatedly filter images?

[Topwiz]

func filterimage(insertImage: UIImage) -> UIImage {
let toonFilter = SmoothToonFilter()
let testImage = insertImage
let pictureInput = PictureInput(image:testImage)
let pictureOutput = PictureOutput()
pictureOutput.imageAvailableCallback = {image in
    // Do something with image
}
pictureInput --> toonFilter --> pictureOutput
pictureInput.processImage(synchronously:true)
}

I'm using this codes to filter still image but the problem is when I filter one image it is ok. But when I filter image repeatedly the pictureOutput has the before filtered image in it.

For example.

let filteredImage1 = filterimage(insertImage: PicOne)
let filteredImage2 = filterimage(insertImage: PicTwo)

When I do this, filteredImage2 has the same image of filteredImage1.

and when I input the third image like this, let filteredImage3 = filterimage(insertImage: PicThree)

this filteredImage3 has the image of filteredImage2

So I tried to use removeAllTargets(), pictureOutput.removeSourceAtIndex(0) after filtering one image but it has no change.

Can anyone help me..

Did you find the decision of the problem?

Yep. But it's a half answer. I was using a live View on the RenderView and changed a little code in gpuimage to get a full size of the .Photo preset. When I use the default func to capture photo it gets 750*1000 size. Using capturePhoto I got a Original image. and I got that image and rendered it again for the filtered image.

But the problem was. I was using camera --> filter --> renderView and getting a live filtered image on the view. But I called inputPhoto --> filter --> outputPhoto. But when I call that I think it crashes with the renderView that is in live. So I just made another renderview in hidden and I put camera --> filter --> renderView2 than I filtered image will live video is going on in renderView1 and it works.

But the problem is as I am using 2 renderView in live it takes ram × 2 ..

I think its not that good way to do this but it works..
