The Uyghur language is a kind of the right to left and concatenate writing language,the connection and the deformation between the characters make the segmentation difficult,the accuracy of the segmentation of the characters is crucial to the recognition.Experiment a Uyghur characters segmentation method which based on the projection histogram of the pixels,including the use of the horizontal projection to separate the line of the text,separate the word and the character without adhesion in the word through the vertical projection,detailed a set of segmentation rules of the conjoined characters according to the information of the horizontal and the vertical projection,in addition the distance of the adjacent valleys of the projection,the width of the characters and the value of the pixel on the baseline,etc.Experimental results show that the method can segment the printed Uyghur text into characters effectively which provide a basis for the recognition of the OCR system.
