Abstract
The methods of image processing and edge detection by wavelet transfor m were introduced into chemistry for determining potentiometric titrat ion end-points. This method was used to deal with the experiment data derectly without introducing artificial error factors in calculation. The accuracy of calculation results can get to the experiment limit au tomatically, and the titration end-points can be determined easily by this method. Very satisfactory results were obtained in the calculatio n.
