Abstract:

Image processing algorithms always affect the quality of the image to which they are applied. Traditionally, the effects of these algorithms are determined using broad image quality measurements such as PSNR, SSIM, VIF and MSE. These quantitative measures, however, do not provide a functional assessment of the image processing algorithms. In this paper, we propose and introduce the use of facial detection as such a functional measurement of image quality after performing image processing transformations on the image. To assess this, we downsampled images containing a combined 953 faces, then upsampled the images using five different image processing operations including interpolation and filtering with different parameters. This process resulted in the misdetection of 12-20 images (and a 14-21% increase in error rate) in comparison to the original set, illustrating the deleterious effect of downsampling and subsequent upsampling on the images.

  • For more than 30 years, IS&T's series of digital printing conferences have been the leading forum for discussion of advances and new directions in 2D and 3D printing technologies. A comprehensive, industry-wide conference that brings together industry and academia, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems?particularly those involved with additive manufacturing and fabrication?including bio-printing, printed electronics, page-wide, drop-on-demand, desktop and continuous ink jet, toner-based systems, and production digital printing, as well as the engineering capability, optimization, and science involved in these fields. In 2016, the conference changed its name formally to Printing for Fabrication to better reflect the content of the meeting and the evolving technology of printing.
