Hey xue looking to your problem I think you should use SketchFilter or Thresholdsketchfilter and play with values to get your desired output, but as you are asking for masking , I'm attaching a code, where I'm using Dissolve to blend two images.

func addColorBlending(withImage : UIImage) {

        let blendImageFilter = DissolveBlend()
        blendImageFilter.mix = 0.3

        let blendImage = PictureInput(image: withImage)
        blendImage.processImage()
        blendImage.addTarget(blendImageFilter)

        let imageToBlendOn = PictureInput(image: self.processingModel.pencileDefaultImage)
        imageToBlendOn.processImage()
        imageToBlendOn.addTarget(blendImageFilter)

        let pictureOutput = PictureOutput()
        pictureOutput.imageAvailableCallback = { imageData in

            DispatchQueue.main.async {
                self.handAndFootImageView.image = imageData
                self.processingModel.blendedImage = imageData
            }
        }

        blendImageFilter.addTarget(pictureOutput)

    }

Here you can tweak blendImageFitler.mix property to get your desired output. Hope it Helps you.
