Title: Interfaces and Algorithms for Manipulating Visual Imagery
ABSTRACT: Digital cameras have made it very easy and cheap to capture the world around us. Yet, the images our cameras record often do not match our experience of a particular scene, or our communicative intent. The best visual depictions usually require extensive editing of the raw imagery. Today, photographers primarily use low-level image- and video-processing tools (e.g. Photoshop, GIMP, Picasa, Premiere, iMovie etc.) for editing. While these tools provide extensive control over the final image, they usually force users to manipulate individual pixels. Casual users rarely have the skills or the patience to work at such a low level. In this talk I'll present a number of interfaces and algorithms we have developed to allow users to manipulate visual imagery at a much higher level. Our interfaces let users focus on making design decisions about the final look of an image, while our algorithms handle the pixel-level details required to achieve the desired look. I'll demonstrate how our interfaces and algorithms work together to make it easy for users to composite, relight, warp and enhance digital photographs and video.
