  • Techniques to improve contrast enhancement
    Patent number: 8606037
    Abstract: An apparatus, system, method, and article for enhancing video sharpness are described. The apparatus may include a media processing node to receive an input image having a first level of contrast, and create an output image having a second level of contrast using a scaled luminance transfer function. Other embodiments are described and claimed.

  • Selective local transient improvement and peaking for video sharpness enhancement
    Publication number: 20060285766
    Abstract: A method of selectively sharpening an image may include, for at least some pixels in the image, determining a frequency content associated with a pixel value in the image. The pixel may be linearly sharpened if the frequency content exceeds a threshold. The pixel may be non-linearly sharpened if the frequency content does not exceed the threshold. In some implementations, the non-linear sharpening may include wavelet decomposition of the image and enhancement of decomposed components.
