Skew Detection from Natrual Scene Images: A Review
نویسندگان
چکیده
Natural scene images are generally captured with portable devices such as mobile phone cameras. Scene images contains text information as part of captured scene. Scene image text poses difficultly in processing as compared to document text due to complexity of scene and open environment conditions. Scene images usually suffer from skew deformation due to inherent nature of portable capturing device and 3D scene. The scene text images must be checked for skew and necessary skew correction has to be applied in order to improve the results of character segmentation and recognition. In this paper, various existing techniques for skew detection of scene images have been discussed. The study cover skew detection techniques for scene images for various scripts with major emphasis on Indian scripts. Keywords-Natural scene images; Skew Detection; scene text extraction; Indian Script __________________________________________________*****_________________________________________________

متن کاملPreference for luminance histogram regularities in natural scenes
Natural scene luminance distributions typically have positive skew, and for single objects, there is evidence that higher skew is a correlate (but not a guarantee) of glossiness. Skewness is also relevant to aesthetics: preference for glossy single objects (with high skew) has been shown even in infants, and skewness is a good predictor of fruit freshness. Given that primate vision appears to e...
متن کاملEfficient Character Skew Rectification in Scene Text Images
We present an efficient method for character skew rectification in scene text images. The method is based on a novel skew estimators, which exploit intuitive glyph properties and which can be efficiently computed in a linear time. The estimators are evaluated on a synthetically generated data (including Latin, Cyrillic, Greek, Runic scripts) and real scene text images, where the skew rectificat...

Today, many automobile companies and researchers have developed various safety systems to reduce fatalities by traffic accidents[1, 2]. In order to prevent traffic accidents by distracted driving, therefore, the proposed system presents the vehicle and pedestrian detection using a novel image representation called equi-height mosaicking system[3]. Furthermore, the proposed system additionally s...
