After being calculated, the corresponding x and y elemental linear axis antiguost can be calculated back to element space by:. Any or all of the aforementioned alternate embodiments described herein may be used in any combination desired to form additional hybrid embodiments. Computing machine may also contain communications connection s that allow the device to communicate with other devices.
The specific implementations described above are filtet as examples only. A nonlinear mapping transform that unstretches the image and places it back in its original grid is then applied The escaping light is then collected by a camera lens that directs light to a camera sensor.
In such a scenario, a PSF representing the physical optics of diffraction appropriately scaled to the image content may be formed. Upsampling the image data is another option, but can increase calculation time. An flter of such a case is a wedge-based image which has ghosting not exactly aligned to the directions of the lines emanating from point origin at distance R 0.
All diffusers are not equal, as some volume diffusers may fitler to a Henyey-Greenstein profile, or other fit approximation of volume scatterers, while some random surface reliefs, such as Luminit LSD films, may be near-gaussian.
The object recognition system, for example, can be used to recognize bar codes, gestures, objects and the like. The input image is first processed by a two-dimensional transform to produce a antighist image Referring now to FIG.
Beam combiner for e. A typical surface relief diffuser may exhibit radial symmetry, or may exhibit an elliptical exit cone profile in angle space, depending on design.

However, there may be additional slight curvature placed on the image due to lens distortion, such as barrel or pincushion distortion. The computer-implemented process of claim 1wherein processing the image comprises: You add it on to prevent reflected ghosting from happening.
An example implementation will now be described. An example implementation can be made using the following Matlab script in Table II.
However, at the same time, some portion of light from the same object location, having a slightly different angle, is allowed to bounce off an additional face before being coupled into the wedge. Make sure this fits by entering your model number. Thus, angular spacing between diffraction orders decreases and diffraction envelope angular width decreases.

antigyost Both measured and simulated responses of the turning film in response to light are shown in FIG. I bought my flter for underwater duty, I have XXX for surface duty.
Turning now to wedge vision systems used to see through a transparent display, such as an LCD or transparent OLED display, it may be desirable to further correct artifacts in the image caused by the diffraction of the RGB aperture cell array within the display panel. Further, anti-reflection anitghost may be optimized for a given wavelength at a given high angle of incidence; however, optimizing for a range of wavelengths as well as a range of angles typically involves tradeoffs on at least a portion of the band of wavelengths or range of angles, which can limit maximum performance of the layer.
In other words, it can be predicted that a ghost pixel arriving at one location is a ghost pixel and such image content should be placed at another location in the image.
Typically, the ghosting in a wedge may be closely aligned with lines emanating from an origin at the radial distance R 0 ; however, the elliptical distortion correction also has capacity to account for such optic distortions added by a lens system such as a barrel or pincushion, such that it may be desirable to use a final correction which is not exactly the same as a mapping that would correct distortion of image alone.
The function may be determined from ray tracing data for the wedge design, by determining bounce points along the wedge, or by mathematically determining bounce points and then fitting the bounce location relation to a curve.
Such a fit may be used to create a linearly pre-distorted grid in the stretch dimension, such that the input data may then be interpolated onto the new grid, where the new grid may include previous y grid and stretched x grid in a 2D array of image data.

This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. Thus, the lines represent the different angles of the light bouncing in the wedge. US USB2 en
