| Abstract: | Image thresholding techniques are analyzed according to the most important part of them,the partial sum algorithm.With two examples,entropic thresholding methods and Otsu's thresholding methods,various partial sum algorithms are introduced from lower to higher dimensions.By their computation strategies,partial sum algorithms are classified to the static and dynamic versions,whose theoretical advances and shortcomings are mentioned.Finally,the key point of the relating problems is drawn up. |
