Thinning is an essential step in many character recognition techniques. Thinning is a process, used at a pre-processing stage for recognizing character. In this paper Z.-Suen and H-W-Lui algorithms are enhanced to Sindhi Optical Character Recognition (OCR). Using aforementioned algorithms the thinning of 4704 Sindhi characters is analyzed. The four thinning algorithm are selected and applied on Sindhi characters data set. The obtained results are analyzed based on the shape and text connectivity. The performance is measure on the basis of text connectivity, and calculating the processing time.
