The correction of digital images obtained by means of low quality scanner using FIR filter generated by a neural network in opposition to the digital images obtained by means of model scanner

Dynamic development of the image acquisition equipment, which bases on CCD matrice, that has occurred in recent years was the cause of the abundance of those devices in household usage. However, this equipment has many disadvantages caused mainly by the quality of the CCD matrice and electronics used to build it. Professional equipment that has high quality parameters and truly mapps an image is still expensive and is owned mainly by professional companies that deal with digital image processing. The aim of this article is to present the possibilities of improvement the quality of images acquired by low class devices, so that their quality is comparable to images acquired by high class devices.

Dynamiczny rozwój sprzętu akwizycji obrazów opartego na matrycach CCD (Charge Coupled Device) doprowadził do tego, że stał się on obecny niemal w każdym domu. Jakość obrazów pozyskanych za pomocą takiego sprzętu w dużym stopniu zależy od jakości zastosowanej matrycy. Celem artykułu jest zaprezentowanie sposobu poprawy jakości obrazów cyfrowych pozyskanych skanerem o niskich parametrach tak, aby ich jakość zbliżyła się do obrazów pozyskanych przy pomocy skanera wysokiej klasy.
