  1. DeFusionNET: Defocus Blur Detection via Recurrently Fusing and Refining Multi-Scale Deep Features. CVPR After that, the fused shallow features are propagated to top layers for refining the fine details of detected defocus blur regions, and the fused semantic features are propagated to bottom layers to assist in better locating the defocus regions.
  2. Standardized defocus curve measurements offer an accurate method to determine visual acuity differences between IOLs at each defocus level. 23,24 A strong understanding of the defocus curves of presbyopia-correcting IOLs helps the surgeon select from a range of IOL options to meet the patient’s preferred visual acuity needs at specific distances.
  3. Run by Clair Poulton (ex-Clear, ex-Rephlex) with CiM, Plus One, Aphelion, John Tejada, Tim Koch, Esem & Lackluster. No longer active, although some old deFocus releases are available in MP3 format from Bleep. Early in its life the label was known as Focus Records .
  4. Defocus definition, to cause loss of focus of: The slightest movement will defocus the microscope. See more.
  5. Hyperopic defocus. Starting at 12 days of age, birds received either 2 daily hours or 6 daily hours of hyperopic defocus induced by the wearing of a monocular −10 D lens at one of the following times of day for 5 days: “morning”: – (n=13) or – (n=6); “mid-day”: – (n=20) or – (n=8) or “evening”: – (n=12) or – (n.
  6. higher-quality “defocus” results than other stereo algo-rithms while also being 10 faster than comparable techniques. 1. Introduction Expensive DSLR cameras are capable of producing shallow-depth-of-field images — objects at a certain dis-tance from the camera are in focus, while nearer or farther objects are out of focus.

  8. Jun 06,  · Defocus blur is very common in images of three-dimensional scenes, especially when the aperture of the camera or the depth range of the scene is large. The defocus amount is often spatially-varying as the depth of the scene usually varies spatially. Therefore, the defocus amount can be used as a cue of depth estimation.
  9. Deconvolution: diffraction and defocus noise free. MIT / Optics 12/12/05 wka Noisy raw image SNR= MIT / Optics 12/12/05 wka Deconvolution using Wiener filter (i.e. Tikhonov with µ=1/SNR) Noise is destructive away from focus (4DOFs).
