The Nonphotorealistic Camera 233

Posted by timothy from the cleverness-applied dept.
An anonymous reader writes "This article on Photo.Net describes a new type of imaging technique that finds depth discontinuities in real-world scenes with multiple flashes added to ordinary digital cameras. As depth discontinuities correspond to real 3D object boundaries, the resulting images look like line drawings. The same technique was used at this year's SIGGRAPH to create a live A-ha 'Take On Me' demo."

    It's interesting to see that people finally wanted to try to obtain from their hardware what they'd usually expect Photoshop filters to do.
    I am for example very happy with my Motorola v550 cell phone camera which takes the trashiest but also most colorful nunrealistic photos.

      I think this is a quantum level above the Photoshop filters on an ordinary photo.

      In a standard photo, where is light and where is dark is only an approximation to 3D properties from a specific angle

      The use of multiple flashes gives a much more complete picture of depth.

      The real question is what is the cost of this process, and how does it compare with laser modeling techniques?

      If the cost and ease of use is not very low, i would say most of the uses of this technology would be better served by the capability of laser scanners to produce a high resolution digital 3D model of an object, rather than a 2D representation of a 3D object.

      • The cost should be minimal. Using a digital camera, a tripod, and just walking around with a remote flash, you should be able to achieve the same results. The hard part is the image processing software that turns the differences in shadow between the images into the outline image. And, while it may help make 3d models you will still need multiple images. I'm not sure this buys you anything over making images of something at specified levels of rotation, and picking common points on the views.

      This technology is a long way from 3-D. First, this camera can only estimate relative depth not absolute depth. Thus, it might determine that the foreground object is half the distance to the camera as the background object, but have no estimate of the numerical distance of either object - the foreground could be 3 feet from the camera and the background would be 6 feet or the foreground could be 5 feet from the camera and the background would be at 10 feet.

      Furthermore, this technology only sees edge discontinuities where a foreground object sits in front of a background object. Thus it cannot tell the difference between a circular disk in the foreground or a sphere in the foreground. Actually it is worse than that because the rounded edge of the sphere will cause errors in the estimation of the relative depth of the sphere vs. the background.

      Even with these limitations, the technology could be quite useful in robotics. Combining multiple edge images using optical flow and knowledge of the robot's motion would yield a more accurate 3-D depth map at least for the purposes of navigation.

      As for extending the technology, a second camera would do wonders for pinning down the distances to each observed edge. The system would still need separate software magic for mapping the front surfaces of objects (e.g. discerning the difference between a 3-D sphere and a 2-D disk).

If these were outside the visible spectrum, then they would not be distracting to humans (as multiple flashes would be), and could be used to build an object-overlay. By using the flashes intermittently, the robot could subtract the ambient image from the flash image to remove the effects of other robots' flashes.

        Well, technically, red eye is avoided with two flashes. One flash surprises the eye and reflects light off it before the pupil has a chance to shrink. Red-eye removal basically takes a "pre-flash" to prepare onlookers for the real picture.

        Sure, and they usually also have some sort of diffuser or umbrella with their flash. Or they'll bounce their flash off the ceiling for the same effect. Or multiple flashes are set up so that each one fills in the shadows
  • This method replaces value-based edge detection with depth-based edge detection, but to get a "proper" line drawing, you'd want to combine the two. That's because line art usually draws both kinds of discontinuities. i.e. We draw a line at the outer edge of an object, regardless of value/color change (which is what this technique does), but we also draw a line between the red and green stripes on an ugly Christmas sweater, despite the fact that there's no depth difference (what traditional edge detection

    This story made me revisit some old bookmarks.

    One of them is Canesta [canesta.com] that makes a photo sensors that can make pictures that include deep maps.

    To my surprise I see that they are running a contest were your can win 10000 $.

    But I don't have time to participate myself, because I am writing on my masters. So enjoy the contest [canesta.com].

    With this, why have only one object in focus? Here's what I mean;

    If autofocus (or any other method) from differnet angles allows for this enhancement, this technique can be used to 'cut' the image into different focus layers.

    Piece the layers together, and you get a photo that has depth of field and is much sharper at each level.

    The layer information could be stored seperately for later processing or combined with only a little fudging to give a weighted blur to the non-primary layer(s). Keeping the layers seperate and doing a comparison would also allow editing tricks such as cutting out objects at a specific depth or performing color enhancements on each level.

  • This technique makes outlines for real-life objects, thus providing the an inportant step for turning real-life objects into cartoons.
  • My degree was in Technical Illustration. I knew then, (15 years ago), that it was inevitable that computers were going to make the field obsolete. (which this technology appears to *finally* achieve to a large degree). So I got into computers.

    However, I *do* believe that this statement:
