Swift 3 + iOS 10 or Swift 4 + macOS 10.13

Mainly working on desktop

For the Cocoa experiment, please refer to Photo Factory folder

• Exposure,
• Shadow & highlight
• Saturation
• Contrast
• HSL for Orange

iOS 11 adaptation will be done before March.

• Real-Time Rendering via MTKView
  • Adapted aspect radio
  • Lowest CPU cost with fewest data type conversion

This way is much more faster than DispatchQueue method.

• Gamma Correction
• Gaussian Blur
• 2D FFT in Metal by a Iterative Way
  • 1st: Rearrangement of element
  • 2nd: Calculate FFT by rows
  • 3rd: Calculate FFT to final stage. (50%)

Thanks to Core Image, you can test these filters by images supported by it. Output is available.

All Kernels locate in CustomKernel functions from CustomFilter.swift, you can also find them in Kernels.cikernel for Core Image Kernel with comments under the iOS directory.

The Metal Kernel is located in macOS folder.

FFT kernel can be found in Computekernel.metal.

This is a final project of the course named Software Engineering. It has friendly UI, and real-time rendering for input image or RAW file. More features are included at report.PDF file in that folder.
