A Morphological expanding of Harris Corners Scattered within Baseline Area for Localization of Uyghur Text Regions in Image Sequences
Gulxax Halelbe · Jiguang zazhi · 2015
To solve the problem of detecting the Uyghur text regions in image sequences,this paper proposed a new method based on combining Harris corners and baseline characteristics of Uyghur text: Firstly,make the conversion to input color image into gray scale,then detect the Harris corners,and then determine the baseline of the probable text area according to the distribution of Harris corners,then carry on morphological expanding operations to the corners within the baseline zone. Finally,the locations of the target text regions are obtained. The experimental results of the tests on a relatively large amount of image sequences show that the practicability and the effectiveness of the proposed method are good enough compared to other similar algorithms.
