Improving mask edges
Hi everyone 👋, amazing framework GPUImage!
I am very new to image processing, sorry if I mix up things.
I am working on a segmentation problem for macOS, I get a mask of size 320x320 that I need to scale up to the original image size then I can applied the mask against it.
The problem I am facing is when scaling up using Lanczos resampling I get very smooth edges in the scaled mask, then when getting the segmented image I can see the background, (this is very noticeable in the hair).
Original image | Segmented image | Small mask | LanczosResampling |
---|---|---|---|
For masking I am just doing:
let maskedImageRef = originalImageCGImage.masking(cgImageMask)
let maskedImage = NSImage(cgImage: maskedImageRef, size: size)
return maskedImage.drawImage()
Any advice on how can I improve make the edges?
Thank you! ❤️
