1 The slightest movement will defocus the microscope.

2 It used shape from defocus technique with diffusion.

3 Defocus is one of the most familiar reason inducing image degradation.

4 Digital image processing is applied to measure the defocus of linear scan CCD with push broom for space remote-sensing camera.

5 A new method to measure the optical defocus of a passive imaging system ( ODPIS ) is proposed.

6 The both methods could adapt well to the defocus and the motion blur simultaneously.

7 A new method for depth measurement based on defocus images was proposed.

8 Integrated filter to defocus the selection mask,[] to avoid problems with noise or grain.

9 Images acquired by the micro-vision system are usually defocus blurred images in micromanipulation.

10 Point spread function (PSF) and Strehl ratio (SR) are used to evaluate the imaging quality of the system with different defocus parameters.

11 A new method for depth measurement of mobile object based on defocus images was proposed.

12 Intensity of Gaussian distribution impacts significantly the sensing signal of the defocus phase, in which the error percentage achieves 25%, but for other phase profile, the effect is ignorable.

13 From analyzing the data of the slope and ET, he speculated that the sensory system in LOM subjects might be less sensitive to defocus than that of emmetropic subjects.

14 The lens may take a variety of shapes, including Fresnel features, and may focus, collimate, or defocus the ultrasonic energy.

15 Our results on experimentation and simulation show that virtual microassembly approach helps to avoid the defocus problem under the microscope and also to make the operation feasible and easier.

16 Moreover, the welding speed effects on the fish-scale spacing and the defocus distance on the weld bead penetration and weld width mainly.

17 It is also shown that only when the gratings are cylinder or plane ones, the second order sagittal anastigmatic circular field and meridional non defocus flat field spectral images can be formed.
