Learn more about machine vision! In our knowledge base we are explaining key technical terms about image processing. We give you an overview to topics like 3D machine vision or the established standards like CameraLink, GigE Vision or GenICam.
Image distortion can be caused by many factors such as lens distortion (see the optics section), or when the camera views a target at an angle to the image plane. Geometric correction is very processor intensive, but can be essential in some applications to obtain a usable image.
There are many arithmetic operations that can be performed on images. These work on a pixel-by-pixel basis; reading one or more pixel values, performing an arithmetic function on the pixel and exporting the result as an output image.
