Binarisation

Binarization aims at setting an object apart from its background thus making the interesting characteristics of the object more apparent.

Cos4 Vignetting

All lenses can potentially suffer from what is called Cos4 vignetting, when the light entering from the extremities of the image strikes the sensor at a shallow angle.

Macro Lenses

Macro lenses are specifically designed for small fields of view (FOV), which are approximately equal to the camera's sensor size.

Aberration

Confer: Spherical Aberration

The images produced from a spherical lens will be subject to increasing amounts of blur towards the edges.

Acquisition

All acquisition signal types transmit image data from the camera to the host system. Each technology has its own strengths and weaknesses and not all mechanisms are suitable for every application.

Analyse Blob

The purpose of a blob tool (sometimes called a connectivity tool) is to measure the parameters of discrete objects within an image.

Aperture

Confer: F-number (F-stop)

The F-number, also known as F-stop or numerical aperture, defines the amount of light that can pass through any lens setup.

Confer: Objectif asphérique

Objectif pourvu de lentilles asphériques.
