The new intelligent i-CS lens directly exchanges information such, as geometrical distortion and the exact position of its zoom, focus and iris opening.
At various times Bouska, Link, Ashbrook, and Soulsby all reported the umbra to be wider east-west than it ought to be, even allowing for Earth's slight spread at the equator and the geometrical distortion in a converging light cone at the Moon's distance.
But the scheme is less effective to other types of geometrical distortion such as local warping due to the interpolation and quantization effect of inverse DFT transform.
The number of connected objects is invariable to the geometrical distortion of an image from a theoretical point of view, unless the image is torn up.
The robustness of the proposed scheme is demonstrated under both geometrical distortion and common image processing operations.
Improved ABBYY Camera OCR technology enables FlexiCapture Engine 10 to achieve better results from photos through enhanced removal of motion blurs, noise in color photos, and geometrical distortion from an image.
Small Shelf Dimensions: Automatically loaded lyophilizers tend to have a relatively large number of relatively small shelves so that the tolerances of individual vials do not build up to cause geometrical distortion to the pack of vials during its transfer onto the shelf.
This is manifest not only as changes in length (linear expansion) but also due to the geometrical distortions caused by the combined effects of temperature, vacuum and pressure over the course of the cycle.
Cooled CCD cameras have several advantages for digital imaging over unintensified and intensified video detectors, including dynamic range, linearity, low noise, and little geometrical distortion.
