| Abstract: | The flows of traditional form frame line removal morphology algorithm are analyzed in detail in this paper: the selection of structuring elements and the speed problem.A form frame line removal morphology algorithm based on adaptive structuring elements is proposed.A threshold based on a simple image statistics is used for binarization processing firstly.Then frame lines and characters are efficiently and accurately extracted based on the hit miss transform of adaptive structuring elements.The parsed exampl... |
