Script determination of mixed Chinese/English document images using Kolmogorov complexity measure
In this paper, we propose an approach based on Kolmogorov Complexity (KC) measuie for determining script classes in mixed Chinese (complex characters)/English document images. This approach, which mainly consists of two steps: document image preprocessing and KC measure, can successfully separate Chinese text lines from English ones. Our approach is robust and reliable in handling document images of different appearances and densities, and various fonts, sizes and styles of characters used in documents. Experimental results on a set of 40 text line images (20 English text lines and 20 Complex Chinese text lines) from various document images show that 100% correct classification rate can be achieved.
