Interactive Contrast enhancement by Histogram Warping

  title={Interactive Contrast enhancement by Histogram Warping},
  author={Mark Grundland and Neil A. Dodgson},
We present an interactive contrast enhancement technique for the global histogram modification of images. Through direct manipulation, the user adjusts contrast by clicking on the image. Contrast around different key tones can be adjusted simultaneously and independently without altering their luminance. Histogram warping by monotonic splines performs the gray level mapping. User interfaces for contrast correction find application in digital photography, remote sensing, medical imaging, and… CONTINUE READING
