The Resolution Synthesis algorithm (ResSynth or RS) is an image interpolation algorithm which computes the minimum mean-squared error estimate of the high-resolution image, given the low-resolution image. ResSynth produces sharper images than the commonly used Bilinear and Bicubic interpolation; and it is computationally efficient. However, the original ResSynth algorithm has some deficiencies, which are: 1) it tends to aggravate noise and JPEG artifacts in the image; 2) it produces halos around strong edges in the image; 3) it occasionally generates “color sprinkles” - pixel errors around the edges. To overcome these problems, we developed the New ResSynth algorithm based on the original algorithm. New ResSynth significantly improves the quality of the interpolated images.

  • For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.

    Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
