Abstract

Hybrid image processing has been described for adaptive binarization by efficiently combining optical analog and digital image processing techniques. A defocused image obtained by an optical system served as the 2-D variable contrast threshold for adaptive binarization in the digital processing. Experimental results show that the method of hybrid image processing is effective for adaptive binarization for simplicity of data handling and economy of computer time.
