A novel method based on lines clustering for extracting multi-ROI in images with simple background

Since application of target recognition is mostly used in multi-object images, extracting interested objects efficiently is much necessary. Taking account of non-curve but regular-shaped objects on simple background, the authors have proposed a novel method based on lines clustering for extracting multi-ROI. Steps of the method have been demonstrated in the article. Experimental data have also given and proved the method effective and practical.
