On-Camera Image Processing Improves System Performance

Facebook X LinkedIn Email
Dr. Joost Van Kuijk, Adimec

An explanation of performance and tips on reducing system costs using cameras with image processing capabilities. Perfect image sensors or lenses do not exist; all have artifacts, introduce noise and distort the “real” image. Even high-quality CCD and CMOS image sensors produce artifacts. In many machine vision OEM instruments, the industrial camera is a critical component, and these artifacts should be eliminated or corrected. Image correction functions can be implemented in the camera, performed by frame grabbers or via software in PC systems such as advanced...Read full article

    binning
    Combining adjacent pixels into one larger pixel, resulting in increased sensitivity and lower resolution, or, in image analysis, excluding objects based on shape, position or area.
    machine vision
    Machine vision, also known as computer vision or computer sight, refers to the technology that enables machines, typically computers, to interpret and understand visual information from the world, much like the human visual system. It involves the development and application of algorithms and systems that allow machines to acquire, process, analyze, and make decisions based on visual data. Key aspects of machine vision include: Image acquisition: Machine vision systems use various...
    noise
    The unwanted and unpredictable fluctuations that distort a received signal and hence tend to obscure the desired message. Noise disturbances, which may be generated in the devices of a communications system or which may enter the system from the outside, limit the range of the system and place requirements on the signal power necessary to ensure good reception.
