In this paper, a bilingual script recognition system is developed to identify and separate out texts written in Devnagari and Gurumukhi scripts. It is observed that vertical half strokes and horizontal strokes are predominantly used in Gurumukhi script compared to Devnagari. On the basis of this observation, we develop a morphological image processing based scheme to extract vertical and horizontal...
Steganography is the art and science of covered or hidden writing. The purpose of steganography is covert communication to hide the existence of a message from an intermediary. Digital Steganography algorithms have been developed by using texts, images and audio etc as the cover media. This paper presents a new approach on text steganography through Indian Languages. Considering the properties of...
Vision-based hand gesture recognition is a popular research topic for human-machine interaction (HMI). We have earlier developed a model-based method for tracking hand motion in complex scene by using Hausdorff tracker. In this paper, we now propose to extract certain features from the gesture trajectory so as to identify the form of the trajectory. Thus, these features can be efficiently used for...
